Re-Register vss in Server 2012

Hi Does anybody know how to re-register vss for server 2012 r2?

Hi,
My WSB backp is failing with:
The backup operation that started at '‎2014‎-‎08‎-‎20T19:42:59.275806600Z' has failed with following error code '0x80780102' (The system writer is not found in the backup.). Please review the event details for a solution, and then rerun the backup operation
once the issue is resolved.
vssadmin list writers confirms this.
Immediatley before the backup fails I get the following error
Cryptographic Services failed while processing the OnIdentity() call in the System Writer Object.
Details:
AddCoreCsiFiles : RtlConvertNtFilePathToWin32Path() failed.
System Error:
0xC0000039 (unresolvable).
My permissions on %windir%/winsxs\filemaps
are correct.
The Hotfix mentioned in the below link is not relevant for 2012R2

Any pointers would be greatly appreciated.

Upgrading from Trial to registered version of Server 2012 Essentials

I believe my Trial ran out.
Arrived in the morning to see my server rebooting right after attempting to scan the registry. During the scan, it reads 0% and erorrs to “If you’d really like to know, it is a registry error”.
I’m able to restart in Safe Mode w/ Network and it appears that the entire domain tree is unresponsive. All data is intact and I’m able to get out to the internet.
Tried to use the repair feature from CD but it states that C: is locked.
Also unable to reinstall due to the drive being locked.
Any suggestions would be greatly appreciated

Hi,
à
I’m able to restart in Safe Mode w/ Network and it appears that the entire domain tree is unresponsive.
I noticed that you can restart the server in Safe Mode. Just a confirmation, please check if be able to run
the server in normal mode again? Then check if can convert the server to full version. Or tell us why be unable to access normal mode?
Please refer to following article and check if can help you.

as a last resort before calling for Tech Support
By the way, did you find any error message when run

Server 2012 R2 - The system failed to register host (A or AAAA) resource records (RRs) for network adapter

We seem to be having an issue recently after introducing new Windows Server 2012 R2 servers where they fail to register DNS correctly. The Windows Firewall is off and the servers are on the same VLAN with no firewalls between them.
When I do an ipconfig /registerdns or wait 24 hours for the system to try we get the following error:
The system failed to register host (A or AAAA) resource records (RRs) for network adapter
with settings:
Adapter Name : {4A0ECF05-193F-4BEA-AA46-BEC593BA752B}
Host Name : SRV-DATA
Primary Domain Suffix : internal.local
DNS server list :
192.168.0.50, 192.168.0.42
Sent update to server : <?>
IP Address(es) :
192.168.0.99
The reason the system could not register these RRs was because the DNS server contacted refused the update request. The reasons for this might be (a) you are not allowed to update the specified DNS domain name, or (b) because the DNS server authoritative
for this name does not support the DNS dynamic update protocol.
To register the DNS host (A or AAAA) resource records using the specific DNS domain name and IP addresses for this adapter, contact your DNS server or network systems administrator.
On our DNS server we have set for the internal.local zone Secure Updates only so that looks good because it is Active Directory that should be handling this authentication to update the record I assume. Just to mention that when also doing an ipconfig /regsiterdns
the update fails within a few seconds.
Source: DNS Clients Events
Event ID: 8018
User: NETWORK SERVICE
This issue is only affecting Windows Server 2012 R2 clients and testing with Windows Server 2008 R2 clients works no issues. So is this a mis-configuration or a bug with Windows 2012 R2? I have checked all DNS settings on client / server which all look good
to me so reaching out now to see if anyone has any ideas?
Environment:
- Windows Server 2012 R2 Domain Controllers (Forest/Domain Levels 2012 R2)
- Windows Server 2012 R2 Client machines (Physical and Virtual)
- Windows Server 2008 R2 Client machines (Physical and Virtual)

The zone is configured as "Secure Only"
The PDC is the SOA for the zone
I dont have a packet capture from the DC, only the client.
The query you asked me to run is too long to paste in here, however this is the DNS zone it cannot update:

Windows Server 2012 VSS error "The system writer is missing"

Hello All,
I have a HP server that I have just installed Server 2012 standard, SQL Server 2012 and Sharepoint 2013.
When I try to take bare metal backup I get the error: "The system writer is missing", I have tried the backup as the local admin and domain admin.
The backup will only work if I decide to back up C:, once I select "Bare Metal" or "System State" the backup fails.
I have tried this solution: http://technet.microsoft.com/en-us/library/cc734021.aspx but have not had any luck yet.
When I run the command "vssadmin list writers" I can not see "System Writer" listed.
How can I add/turn on the System Writer?

Hi,
The system writer fails due to the fact that the trusted installer & system accounts are missing permissions to files in the directory %windir%\winsxs\filemaps\.
To resolve this issue, please run the following commands from an administrative elevated Command Window:
CD c:\windows\system32
Takeown /f %windir%\winsxs\filemaps\* /a
icacls %windir%\winsxs\filemaps\*.* /grant "NT AUTHORITY\SYSTEM:(RX)"
icacls %windir%\winsxs\filemaps\*.* /grant "NT Service\trustedinstaller:(F)"
icacls %windir%\winsxs\filemaps\*.* /grant "BUILTIN\Users:(RX)"

If I run 'vssadmin list writers' after the backup job completes, all writers report their state as stable with no errors.
I came across this error recently when trying to troubleshoot another issue, but looking back, I can see that these have been going on for a while. The first instance I see occurred in early March.
Any suggestions on what I can do to clear up this error?

Custom Data Provider Not Registered in Report Server (Sql Server 2012)

We have a simple test report project set up and can preview the reports with no errors or problems from the designer. We can deploy the report project, but when trying to view the reports from the browser, we get the following error:
An error as occurred during report processing, (rsProcessingAborted)
An attempt has been made to use a data extension 'LiMeDAS' that is either not registered for this report server or is not supported in this edition of Reporting Services. (rsDataExtensionNotFound)
I have followed this article that explained how to register a data provider extension:
https://msdn.microsoft.com/en-ca/library/bb326409.aspx
I have placed the assemblies in:
C:\Program Files\Microsoft SQL Server\MSRS11.LIMEDAS\Reporting Services\ReportServer\bin
Added the following line to the rsreportserver config file (inside the <extensions><data> tags)
<Extension Name="LiMeDAS" Type="Limedas.Data.Provider.LimedasConnection,Limedas.Data.Provider"/>
and finally added the following to the rssrvpolicy config file (inside the top level CodeGroup tag):
<CodeGroup class="UnionCodeGroup" version="1" PermissionSetName="FullTrust" Name="LiMeDASDataProviderCodeGroup" Description="Grants permission to the LiMeDAS data processing extension for reporting services.">
<IMembershipCondition class="UrlMembershipCondition" version="1" Url="C:\Program Files\Microsoft SQL Server\MSRS11.LIMEDAS\Reporting Services\ReportServer\bin\Limedas.Data.Provider.dll"
/>
</CodeGroup>
We have the data extension set up perfectly for the designer, because I can see it as a type of connection and the preview works in the designer.
But, for some reason it does not work in the server. They were set up the same way, but the server will not work. From the report manager page, when we try to add a data source, the only type option is Sql Server, none of the other extensions mentioned in
the config file. Does anyone know what else could cause this issue?

Hi Justin,
According to the error message and the issue can be caused by the edition of your SSRS is not support for the custom data provider. For example the express edition have limitation support on this:
Features Supported by the Editions of SQL Server 2012 .
If your edition is the supportted edition and the issue can be caused by the custom data provider do not necessarily support all the functionality supplied by Reporting Services data processing extensions. In addition, some OLE DB data providers and ODBC
drivers can be used to author and preview reports, but are not designed to support reports published on a report server. For example, the Microsoft OLE DB Provider for Jet is not supported on the report server. For more information, see
Data Processing Extensions and .NET Framework Data Providers (SSRS).
If you are running on a 32-bit platform, the data provider must be compiled for a 32-bit platform. If you are running on a 64-bit platform, the data provider must be compiled for the 64-bit platform. You cannot use a 32-bit data provider wrapped with 64-bit
interfaces on a 64 bit platform.
More details information:Data Sources Supported by Reporting Services (SSRS)
Similar thread for your reference：

Does DPM 2012 R2 still needs DataSourceGroups.xml and MaxAllowedParallelBackups key when using Hyper-V VSS Software Writer to backup Server 2012 R2 Cluster

Hi,
Does DPM 2012 R2 still needs DataSourceGroups.xml and MaxAllowedParallelBackups key when using Hyper-V VSS Software Writer to backup Server 2012 R2 Hyper-V Cluster with CSV's? Can't find a clear answer somewhere.
Thanx for helping me out.
DJITS.

Configure CSV backups
If you are running Hyper-V on Windows Server 2008 R2 and you’re backing up multiple clusters with DPM, you need to ensure that only one backup uses the same CSV at any one time. To do this, follow the instructions in
Serialize virtual machine backups.
If you’re using software VSS with Hyper-V on Windows Server 2008 R2, do the following
Serialize virtual machine backups per node
Serialize virtual machine backups per CSV LUN
Have a nice day !!!

VSS problems on Server 2012

We have a number of Server 2012 servers and two Server 2012 R2 servers. I use Windows Server Backup to back them up nightly to a remote share. This worked fine on them for several weeks. About two weeks ago, one of the Server 2012 servers
began to have the following problem:
- Backup failed saying the System Writer could not be found
- Listing writers showed it was not there
- A lot of stuff on the web talked about permissions issues but this did not seem to be the case.
- Just restarting the Cryptographic Services service fixes the problem for that day - I can backup multiple times in the same day. But overnight the problem recurs until I restart the Cryptographic Services service
A few days later one of my Server 2012 R2 servers had the problem. Restarting cryptsvc fixed it, and the problem did not recur for a few days. Then it did.
So right now:
- One Server 2012 server has to have the cryptsvc restarted daily
- One Server 2012 R2 server has to have it restarted occasionally - maybe once a week.
There has been no change - no new software, etc - in either server. The backups worked fine for weeks and then this problem happened.
The Server 2012 server is an admin server and has a lot of software installed; the other has the Pulse software installed and nothing else.
I have tried a number of recommended solutions off the web, all to no avail.
Any help would be appreciated.

Hello John,
System State backup using Windows Server Backup fails with error: System writer is not found in the backup
http://support.microsoft.com/default.aspx?scid=kb;en-US;2009272
The issue is caused by a permissions issues with the COM+ Event System Service.
Check for the existence of a GPO that is setting this permission or if this was not intended then you can simply reset the permissions for the Service Logon User. In this case that is the Local Service.
Checking for the GPO:
Start Group Policy Manager
Expand Policies then Windows Settings and then Security Settings
Under Security Settings locate System Services and click on it
Locate "COM+ Event System" in the list of services and confirm that both the "Startup" and "Permissions" columns are set to "Not Defined".
If these are settings are configured you will need to consult with the customer as to what purpose this serves in the environment before making any changes
NOTE: Making changes to a group policy can effect all computers in which the policy applies to. Take extra care to confirm that the changes you are making will not affect the environment negatively.

...that no computers are registered to receive updates (Server 2012) WSUS issue

Hi
Server 2012 64-bit WSUS install
I have trolled as many forum posts as possible but they seem to relate to older versions of Windows OS.
I have clicked the "To set up a client computer" and followed all the steps to create a GPO etc.
However the computers on the domain still look to the internet for their updates and not the WSUS server despite the policy in place.
WSUS is sync and I have 1987 security updates waiting, 626 critical updates waiting etc.
I have approved 562 updates and declined 1338 so far.
I have created 8 separate computer groups.
What can I do to get my domain computers looking to the WSUS server to receive their updates?
Many thanks
Leo

I would suggest starting with
Update and Configure the Automatic Updates Client Computer in the WSUS Deployment Guide, and the
Step-by-Step Guide to Understanding the Group Policy Feature Set.
The links provided point to solutions for much older OS. I am running a Windows 2012 Server environment with Windows 8 OS on client PC's. All the data provided on the link is for Server 2000/2003 and Windows XP. Must I assume that nothing has changed in terms
of registry values and methods of solution?
Very little has changed, the principles are the same, the Admin UI has evolved/modernised somewhat.
Windows8 does have a slightly changed auto-updating behaviour (relating to the post-install-restart behaviour) , but this is able to be modified with a GP setting.
The main settings for a client, continue to be controlled by the same registry settings (keys/values), and this can be configured by GP, and the resultant settings can be observed in the registry.
The applied settings, are consumed by the WUAgent and output to the windowsupdate.log, so it's easy to confirm if your GP settings are being applied correctly as expected.

SharePoint Foundation 2013 installed on Windows Server 2012 not sending out email notification

I have a server where i installed SP Foundation 2013 on top of Windows Server 2012. I have configured the SMTP as well as the outgoing SMTP in Central Administration
of SharePoint. When i create an alert on a document library, its did not sent any email notification on the changes made to the document in the document library. So, i created a workflow to send out email using SPD2013. The workflow run, but it cannot sent
out email with error saying that outgoing email is not configured correctly. I have checked with another server which i installed SP foundation 2013 on top of Windows Server 2008 R2 - its sending out email just fine using same configuration and outgoing SMTP.
I need help to resolve this issue or at least the cause of the problem.
Any help is greatly appreciated.

Try below:
http://social.technet.microsoft.com/wiki/contents/articles/13771.troubleshooting-steps-for-sharepoint-alert-email-does-not-go-out.aspx
Go to Central Admin ---->Operations----->outgoing email settings and verify that SMTP server is mentioned correctly
2) Test the connectivity with the SMTP server.
In order to do that follow these steps:
Open cmd
telnet <SMTP server name> 25 ( We connect smtp server to the port 25)
you should see a response like this 220 <servername> Microsoft ESMTP MAIL Service, Version: 6.0.3790.3959 ready at date and time
Beware that different servers will come up with different settings but you will get something
If you dont get anything then there could be 2 possible reasons, either port 25 is blocked or
the smtp server is not responding.
For testing response from your server
For testing response say ehlo to it.
Type :
ehlo <servername>
output:
250 <servername> Hello [IP Address]
Now a test mail can be sent from that SharePoint server.
Now we need to enter the From address of the mail.
Type :
mail from: [email protected]
output:
250 2.1.0 [email protected]….Sender OK
It's time to enter the recepient email address.
Type : rcpt to: [email protected]
output:
250 2.1.5 [email protected]
Now we are left with the data of the email. i.e. subject and body.
Type : data
output:
354 Start mail input; end with <CRLF>.<CRLF>
Type:
subject: this is a test mail
Hi
This is test mail body
I am testing SMTP server.
Hit Enter, then . and then Enter.
output:
250 2.6.0 <<servername>C8wSA00000006@<servername>> Queued mail for delivery
Type: quit
output:
221 2.0.0 <servername> Service closing transmission channe
3) Check alerts are enabled for your web application
verify if the windows timer service is running or not.
Run this stsadm command to check that
Stsadm.exe -o getproperty -url http://SharePoint-web-App-URL -pn alerts-enabled
This should return <Property Exist="Yes" Value="yes" />
If you don’t get this, Enable alerts by:
stsadm.exe -o setproperty -pn alerts-enabled -pv "true" -url http://SharePoint-web-App-URL
If its already enabled, try turn off and turn on it back.
4) Check the Timer job and Properties
Go to
MOSS 2007: Central Administration > Operations > Timer Job Definitions (under Global Configuration)
In SharePoint 2010: Central Administration > Monitoring > Review Job Definitions
Check whether the "Immediate Alerts" job is enabled for your web application. check these properties:
job-immediate-alerts
job-daily-alerts
job-weekly-alerts
stsadm.exe -o getproperty -url "http://Your-SharePoint-web-App-URL" -pn job-immediate-alerts
The expected output is:
<Property Exist="Yes" Value="every 5 minutes between 0 and 59"/>.
If you don’t get this, run the following command to set its value.
stsadm.exe -o setproperty -pn job-immediate-alerts -pv “every 5 minutes between 0 and 59" -url http://Your-SharePoint-web-App-URL
5) Check whether the account is subscribed for alerts and it has a valid email account. This should be the first thing to check if the problem persists for some users not for all.
6) Then check if at all those users have at least read permission for the list. Because the first mail should go out for every user without security validation but the next ones won't be delivered unless the user has at least read
permission.
7) If it is happening for one user, can also try to delete and re add the user in the site.
8) Most importantly , you should try this one.
Run this SQL query to the content db < Select * from Timerlock>
This will give you the name of the server which is locking the content database and since when.
In order to get rid of that lock
Go to that server which is locking the content db and then restart the windows timer service.
within some time it should release the lock from content db, if not then at the most stop the timer job for some time
Once the lock will be released then try to send some alerts
You will surely get the email alert.
I found this is the most probable reason for alert not working most of the time. We should start troubleshooting with above steps before coming to this step for any alert email issue but from step 1 to step 7 are best for new environments or new servers.
If the issue is like this ,alert was working before and suddenly stopped working without any environmental change then above conditions in step 1-7 should be ideally fine.
Even after this if it is not working, then you can try these few more steps too
9) Try re-registering the alert template:
stsadm -o updatealerttemplates -url http://Your-SharePoint-Web-App-URL -f "c:\Program Files\Common Files\Microsoft Shared\web server extensions\12\TEMPLATE\XML\alerttemplates.xml" -LCID 1033
10) Try to clear the configuration cache
If this helped you resolve your issue, please mark it Answered

Windows 8 and Server 2012. Not detecting network is a domain.

Hi Guys,
I hope I have posted this to the correct forum.
I have 2 x Windows 8 PCs that do not detect that they are connected to a domain (network location awareness not working). I can join them to the domain but they still don't recognise the network as a domain. Instead they identify it as "private".
Other PCs on the network (Win XP and Win 7) work prefectly, just the windows 8 machines don't work.
Also, when I do join them to domain I also receive this message.
"changing the Primary Domain DNS name of this computer to "" failed. The name will remain xxxx.local. The error was: the specified domain either does not exist or could not be contacted. "
I have tried the following
- DHCP and DNS has being tried both as static and dynamic (can ping DNS server which is the domain controller Windows Server 2012) .
- Updated PC NIC drivers.
- No AV is installed on either server or PC.
- Updated PC to windows 8.1.
- Disabled both server and PC firewalls.
- Check NLA service and all dependent services are running.
- Disabled all adapters on server except for one.
I am really hoping someone can help with this as I would really appreciate it.
Thanks.
Shaun

Hi Guys,
I managed to find a solution to the problem. I noticed that the DNS server zones did not look quite right. The _msdcs zone was missing the subfolders (dc, domains, gc, pdc).
To fix this issue: on the NIC adapter I had to tick the box "register this connection's addresses in DNS" (found under TCP/IP v4 > advanced > DNS tab).
I then had to remove the DNS role, reboot then re-add the role. Problem solved. Hopefully this saves someone else pulling their hair out for an entire day.

DLINK DGS-1210-16 - Both the network cards of the Hosts that are dedicated to the Storage and the Storage itself are connected to the same switch and nothing else is connected to this switch.
Virtual Machines:
3 Windows Server 2012 Standard - 1 DC, 1 FileServer, 1 Application Server.
1 Windows Server 2008 Standard Exchange Server.
All VMs are using dynamic disks (as recommended by Microsoft).
Updates
We have applied the most resent updates to the Hosts, WMs and iSCSI SAN about 3 weeks ago with no change in our problem and we continually update the setup.
Normal operation
Normally this setup works just fine and we see no real difference in speed in startup, file copy and processing speed in LoB applications of this setup compared to a single host with 2 10000 RPM Disks. Normal network speed is 10-200 Mbit, but occasionally
we see speeds up to 400 Mbit/s of combined read/write for instance during file repair
Our Problem
Our problem is that for some reason all of the VMs stops responding or responds very slowly and you can for instance not send CTRL-ALT-DEL to a VM in the Hyper-V console, or for instance start task manager when already logged in.
Symptoms (i.e. this happens, or does not happen, at the same time)
I we look at resource monitor on the host then we see that there is often an extensive read from a VHDX of one of the VMs (40-60 Mbyte/s) and a combined write speed to many files in \HarddiskVolume5\System Volume Information\{<someguid and no file extension>}.
See iamge below.
The combined network speed to the iSCSI SAN is about 500-600 Mbit/s.
When this happens it is usually during and after a VSS ShadowCopy backup, but has also happens during hours where no backup should be running (i.e. during daytime when the backup has finished hours ago according to the log files). There is however
not that extensive writes to the backup file that is created on an external hard drive and this does not seem to happen during all backups (we have manually checked a few times, but it is hard to say since this error does not seem leave any traces in event
viewer).
We cannot find any indication that the VMs themself detect any problem and we see no increase of errors (for example storage related errors) in the eventlog inside the VMs.
The QNAP uses about 50% processing Power on all cores.
We see no dropped packets on the switch.
(I have split the image to save horizontal space).
Unable to recreate the problem / find definitive trigger
We have not succeeded in recreating the problem manually by, for instance, running chkdsk or defrag in VM and Hosts, copy and remove large files to VMs, running CPU and Disk intensive operations inside a VM (for instance scan and repair a database file).
Questions
Why does all VMs stop responding and why is there such intensive Read/Writes to the iSCSI SAN?
Could it be anything in our setup that cannot handle all the read/write requests? For instance the iSCSI SAN, the hosts, etc?
What can we do about this? Should we use MultiPath IO instead of NIC teaming to the SAN, limit bandwith to the SAN, etc?

Hi,
> All VMs are using dynamic disks (as recommended by Microsoft).
If this is a testing environment, it’s okay, but if this a production environment, it’s not recommended. Fixed VHDs are recommended for production instead of dynamically expanding or differencing VHDs.
Hyper-V: Dynamic virtual hard disks are not recommended for virtual machines that run server workloads in a production environment
http://technet.microsoft.com/en-us/library/ee941151(v=WS.10).aspx
> This is the primary host and normaly all VMs run on this host.
According to your posting, we know that you have Cluster Shared Volumes in the Hyper-V cluster, but why not distribute your VMs into two Hyper-V hosts.
Use Cluster Shared Volumes in a Windows Server 2012 Failover Cluster
http://technet.microsoft.com/en-us/library/jj612868.aspx
> 2 teamed NIC dedicated to iSCSI storage.
Use Microsoft MultiPath IO (MPIO) to manage multiple paths to iSCSI storage. Microsoft does not support teaming on network adapters that are used to connect to iSCSI-based storage devices. (At least it’s not supported until Windows Server 2008 R2. Although
Windows Server 2012 has built-in network teaming feature, I don’t article which declare that Windows Server 2012 network teaming support iSCSI connection)
Understanding Requirements for Failover Clusters
http://technet.microsoft.com/en-us/library/cc771404.aspx
> I have seen using MPIO suggests using different subnets, is this a requirement for using MPIO
> or is this just a way to make sure that you do not run out of IP adressess?
What I found is: if it is possible, isolate the iSCSI and data networks that reside on the same switch infrastructure through the use of VLANs and separate subnets. Redundant network paths from the server to the storage system via MPIO will maximize availability
and performance. Of course you can set these two NICs in separate subnets, but I don’t think it is necessary.
> Why should it be better to not have dedicated wireing for iSCSI and Management?
It is recommended that the iSCSI SAN network be separated (logically or physically) from the data network workloads. This ‘best practice’ network configuration optimizes performance and reliability.
Check that and modify cluster configuration, monitor it and give us feedback for further troubleshooting.

Disappearing disk space Windows Server 2012 R2 with SharePoint Server 2013 Enterprise

I've got an interesting problem with a virtual machine in our VMWare environment. It is Windows Server 2012 R2 with SharePoint Server 2013 Enterprise installed. I started out with a 60GB disk and it started running out of space, so I increased
it in VMWare and extended the partition to 100GB. Well, that lasted for a bit and so I extended it again. I've done this 3 or 4 times and now I've got a 160GB disk with about 2-3GB of space remaining (and it started with 10GB remaining).
WinDirStat shows 105GB of <Unknown> space being used, which is probably my issue. However, I can't determine what this is and it keeps growing like a tapeworm. The context menu on the <Unknown> files has all the options disabled,
so WinDirStat doesn't appear to have access to whatever the file(s) is/are. I've performed several chkdsk /f on the C: drive and nothing bad is reported. I don't have any restore points and am not running VSS (that I'm aware of). The pagefile
reports as being about 4.9GB, so that's not the issue. No large files are shown anywhere and my explorer settings are set to show me all files, including system files.
When I try to run WinDirStat with elevated permissions, it hangs and becomes unresponsive.
I've even resorted to running CCleaner to see if it found anything, but it simply found the standard temp files and such...about 1GB.
I'm pulling my hair out...and I don't have much to start with. Anyone have any ideas?
Thanks
Russ

It appears that somehow, Microsoft Fusion Assembly binding logging was turned on and many of the temp folders located at c:\users\username\AppData\Local\Microsoft\Windows\InetCache\IE were filling up with hundreds of thousands of Fusion HTM log files.
This is controlled by an entry in the registry HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Fusion\ForceLog which was set to 1. Hopefully, setting it back to zero will fix the issue. As a result of figuring this out, I have recovered almost 80GB of disk
space occupied by the log files.
I thought WinDirStat would show me what I needed to know, but it turns out TreeSize (which I've used in the past) works much better.

Windows Domain Controller on Windows Server 2012 R2: Hyper-V roaming profiles not loading due to slow connection

I have racked my brain and done everything that I know to do for about two weeks now. I am setting up a new system at our fire department and I am having the worst luck with getting the workstations to login to the domain controller with roaming
profiles. It keeps telling me that the roaming profile could not be loaded because of a slow connection. These are workstations that are connected directly to the switch that the DC is connected to. I have tried multiple connections regarding
the layout (DC into the router, router into the switch). The router is a Cisco RV220W. I have two VLANS, one for public and one for private domain. The Private VLAN has DHCP turned off since I am providing it through the DC. I currently
have a connection from the Private VLAN going to the unmanaged switch that the workstations and server are plugged into.
The server is a Dell PowerEdge R420 that has 6 NIC ports (1 dual port and 1 quad port). I have a virtual switch setup on Hyper-V for an external port (let's say Card 2 Port 3) that is assigned to the WS 2012R2 Domain Controller. The DC can see
the internet fine and the workstations can connect to the shared folders on the server. I can retrieve files by just using the computer name or FQDN. The DC is also running DNS and DHCP. The DNS has the _msdcs setup from when I installed
the active directory role. I have attempted to assign static IP addresses to the workstations:
IP:                     10.0.0.80
Subnet:             255.255.255.0
IPV4 Gateway: 10.0.0.1
IPV4 DNS:        10.0.0.12
I've attempted "append the specific DNS suffix", I've "registered the connection in DNS", I've used "use this connections suffix in DNS registration".
The server is assigned:
IP:                     10.0.0.12
Subnet:             255.255.255.0
IPV4 Gateway: 10.0.0.1
IPV4 DNS:         10.0.0.12
The DNS entries have forwarders that forward to my ISP DNS servers for lookup
I've enabled and disabled DHCP, I've installed a new VM just to create another DC to make sure that I didn't goof up when I created it.
I've lost my patience with this project and am sinking fast. Can someone please offer some advice as to what I've done wrong? I've created this exact scenario at work many times but, I've never done it with Windows Server 2012. Is this
possibly something to do with the Dell PowerEdge server (Generation 12) with the SR-IOV? I am going to attempt to work on it some more tomorrow when I get over there. I think there may be an issue with the SR-IOV not being enabled on the machine
through the Dell Bios. Would the SR-IOV really cause the workstations to report a slow connection? When I login at the domain controller the roaming profiles and folder redirection work fine so, I know the GPO settings are correct. I don't
have "ignore slow connections" or any of those GPO's set. I need to get it working the correct way so, I didn't want to fool the server when there is another underlying problem. Any help that someone can offer, I am more than willing
to listen. If you need more information, please ask.
Thanks,
Jay

So, I've managed to research this some more since Thursday and I've come to the conclusion that Hyper-V does a horrible job of supporting Qualcomm NIC cards. That's the only thing I can conclude as far as where the issue is originating. I've read many
post and walkthroughs but nothing that has helped. The issue wasn't with any settings in the domain controller. The issue was that there really is a slow connection originating at the domain controller that is a VM and has network connectivity through the
virtual switch from Hyper-V. So, next question is, how do I get the DC to have better connectivity through the NIC that Hyper-V won't give it? If hyper-v would allow passthrough, this would be so much simpler. VM-ware is looking really good at this point.
Im disappointed in MS right now.

Remote Desktop Gateway on Windows Server 2012 R2 and IPAD

Hi guys,
Would love some help with an issue I been struggling for a couple of days now.
I have a RDS 2012 R2 Gateway configured and it works great with all Windows clients both internal and external communication. The problems comes now when my I want to use IPAD
from APPLE. I installed latest RD Client from Microsoft and it works great from the internal network but as soon the device is moved to an external network the client get an error while connecting. Gateway is located in the domain network.
The error is “Failed to parse authorization Challenge”,
This is what I see in the log file from the RD Client.

Hi Jeremy,
I found a solution, thanks for you effort. The solutions is the following.
First thing that needs to be done is either solution from options below, I did the Solution 1 in my case and added a NPS server to AD. (https://blogs.technet.com/b/networking/archive/2010/01/14/remote-desktop-gateway-client-fails-authentication-with-your-user-account-is-not-authorized-to-access-the-rd-gateway.aspx)
Solution 1
Register the NPS server in Active Directory:
In Server Manager, browse to the following location: Roles\Network Policy and Access Services\NPS (Local).
Right click on the NPS (Local) node and choose Register server in Active Directory.
Click OK to authorize the server when prompted.
Solution 2
Open Active Directory Users and Computers on any Domain Controller of the same domain as the Remote Desktop Gateway.
Add the Computer Name of the Remote Desktop Gateway to the RAS and IAS Servers group.
Situation B
Restart the RDS host and Gateway server.
Secondly and the most important is to configure an alternate address that match your public certificate. My public certificate CNAME is “remote.domain.se”.
All commands need to be run as administrator in PowerShell
To show you current configuration run the following commands:
CollectionName is the Collection Name you created for the RDS deployment.
To get your collection name type
Get-RDSessionCollection
When you got the collection name type
Get-RDSessionCollectionConfiguration -CollectionName "RDS - Terminal Server" | FL *
The default configuration will look like this:
CustomRdpProperty     : use redirection server name:i:1
No to add you public domain name that match the certificate run the following command
Set-RDSessionCollectionConfiguration –CollectionName " RDS - Terminal Server " -CustomRdpProperty "use redirection server name:i:1 `n alternate full address:s:remote.domain.se
Run again to verify your settings
Get-RDSessionCollectionConfiguration -CollectionName "RDS - Terminal Server" | FL *
Now it show look something like this
CustomRdpProperty     : use redirection server name:i:1
                         alternate full address:s:remote.domain.se
IPADs and iPhones can now connect to your environment.
