Strange Server 2012R2 Networking Disconnect On Reboot Issue

Strange issue. Server 2012R2, Dell R710, Broadcom BCM5709C eth adapters. 2 of the adapters are on a LAG for hyper-v. 1 is not connected, 1 is connected for management.
Every time the server reboots, the management interface does not connect. The only fix is to connect via the DRAC, disable the not-connected adapter, then enable the not-connected adapter and then it properly connects to the network. Prior to that it shows up as "unidentified network"

Windows Server 2012R2 network start working very slow?

The is no problem with excel. Network is slow. All other network applications are opening and working slow as well.
So far I have checked physically connection between server and PC through switches, routers and servers. All seems to be OK.

After a few months our network, based on Server 2012 R2, start working very slow.
When you want open for e.g. excel 2013 file from network drive its take ages and also any changing within spreadsheet making excel not responding.
Any idea how to speed up network again?

Windows Server 2012R2 disks go offline after reboot

Hi all,
I've a strange issue in my brand new Windows Server 2012R2, let's describe the environment:
Hypervisor = VMware ESX 5.5
Guest OS = Windows 2012 R2 Standard Edition
I've configured the guest OS with several disk for a SQL Server installation, each disk are presented as "pure" virtual disk to Windows that means no RDM (pass through disk).
After a reboot I've discovered that SQL Server has failed to come online, on a brief analisys, all the disks except system drive (C:) and a volume dedicated to swap file (D:) have not come online. They are present in disk management, but they are offline.
I've manually brung online those disk, than reboot and all returned to normality. Subsequent reboot have generated no issues.
In the system log I have no error message except that one of SQL that fails to came online due to the lack of disks...

This happened to me too. Except with server 2008 R2 and exchange 2010. My servers replicate offsite using zerto and I was testing failover and noticed the drive D was offline. Brought it online then rebooted and everything was fine.
So I just build a server 2012 R2 Datacenter edition VM on my production servers, gave it a second disk, initialized it, formatted it and assigned it the drive letter D. Rebooted after installing 3 windows updates and it was offline. There is nothing on this
server at all. It's a fresh install.
I'm running ESXi 5.5 build 2302651 with hardware version 8 and VMware tools version 9.4.11 build 2400950.
From my experience when you see this kind of stuff happen in multiple situations it will happen again. My worry is what if one of my hosts decides to die and HA kicks in and the disk is offline when it boots.
Anyone have anything to add to this?
Edit: My DR site where I tested my failover is DAS and my production site is iscsi. So I don't think the storage type matters.
Edit 2: The SCSI controller type is Paravirtual for all my VM's.

How to resolve "The server is unavailable and could not be accessed. The server is probably disconnected from the network." error in Sharepoint serach crawl.

Hi all,
I have created a content source in Search service application for a particular site collection "http://spwebapp/sites".
I performed reset crawl index of Search service application and then performed a full crawl.
But i get errors on running crawl on this content source for most of the files. The error is "The server is unavailable and could not be accessed. The server is probably disconnected from the network." Though the site is accessible.
But before performing reset index the crawl was working fine on this content source. Crawl is working fine for other site collections. Only one site collection is facing this problem. Please let me know if what I can do to resolve this error.
Thanks in advance.

Are you seeing any error messages in the URL related to the Gatherer? And in your content source, are there any site URLs that are no longer active or do you have any crawl rules set up that might be affecting access to the site collection?
I've seen this happen for a variety of reason, SSL issues, proxy issues, permissions issues. The Eventvwr and ULS logs should help you narrow down the real problem.
Sometimes this is an issue because the indexer and the site are sitting on the same box, you could try doing a disable loopback check to see if that resolves the issue and if it does then go through the hassle of setting up a specific LSA :

Windows Server 2012R2 RDS sound and smartcard redirection issues

We are using RDS collection with two Windows Server 2012R2 session hosts. Both hosts are virtual servers (clean installation) and are used as session hosts (terminals) with 10 to 25 users each. RDS Connection Broker is also virtual machine with
Windows Server 2012 R2. Our users are using Windows 7 Embedded thin clients with MSTSC RDP 8.0.
Our terminals are running correctly after fresh boot, but in 12 to 48 hours after boot we encounter problem with sound and smardcards redirection in RDP. Remote sound stops working and users cannot login with their smardcards.
Relogging users doesnt help, deleting profiles doesnt help, restarting sound service doesnt help, only viable way to solve issue is server restart. There is not any event in event log about this issue.

Hi,
Thank you for posting in Windows Server Forum.
Sound Redirection:
Please check the following GP setting as well.
Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Device and Resource Redirection
Limit audio playback quality: Enabled
Audio Quality: High
On the Client PC, in the .rdp file that you use to connect to the server, make sure you have the following line:
audioqualitymode:i:2
In addition check that the Windows Audio and Windows Audio Endpoint Builder services must be running for audio to work.
Smartcard redirection:
Kindly try to update the patch for Smartcard redirection and check the result.
Smart card redirection in remote sessions fails in a Windows 7 SP1-based RDP 8.1 client

Issues with running Server 2012R2 Essentials as an Offline Standalone Root CA?

Hi everyone,
   I've searched this forum as well as Google and have not been able to find any concrete answers so I am hoping one of you experts will be able to assist me.
   I have an all Windows 2008 server/domain enviroment.   I was looking at implementing a two-tier PKI with an offline, standalone root CA and an enterprise issuing CA (2008 member server).   Budgets are tight so I was hoping
I could get away with using Server 2012R2 Essentials as the offline standalone root.
   It is my understanding that 2012 Essentials is configured as a DC by default and needs to remain that way per licensing.   I know the recommended configuration for an offline root would be to have the server be in a workgroup and not
on a domain.
   So question 1 is will 2012 Essentials work as an offline standalone root?
   Question 2 is will there be any issues with it running as described?   In other words will the fact that it is the sole DC in its own domain cause issues with its use as an offline root?
   Thank you in advance for your help!

The essentials experience role runs on server standard and is very different from the essentials product in both licensing and pricing. While you can indeed buy standard and deploy the essentials experience role as a "standalone" server, there
would be ZERO benefit in a PKI offline root scenario the essentials role has no automation or configuration options in the dashboard for that use case, and pricing, you'd still be paying for server standard.
The essentials product (or SKU) has the benefit of reduced cost, but cannot be deployed standalone and has enough other restrictions that it is not well suited for the given desired use.
So either way, my answer stands. Essentials (prodct it role) is not the right tool for the job in this case.

Strange Server Reboots on Solaris8 + Weblogic 7 SP2/SP3

Hi all,
I'm hoping that some of you guys can give me some pointers to help diagnose a
serious problem we are having with our servers.
Symptoms:
2xSolaris8 E220s machines running weblogic Express Premium v7 SP3 configured as
cluster. 1 of the servers unexpectedly reboots (with no user action). The server
comes back to runlevel 3 however most of the hard disk partitiions are not mounted.
The hard disks were manually repaired and remounted.
So my question is why did this server decide to reboot and why did the hard disks
not remount?
The only log I can find at the time of failure was found using the following command:
last | morereboot system boot Thu Jul 31 11:04
We did not issue this command, is it possible that the system may issue this command
after a component failure / kernel panic?
We had a similar reboot issue happen last week on our staging servers, these however
were using Service Pack 2.
The things that have changed recently on these boxes are:
- Solaris Tuning parameters have been applied
- WebLogic installed (replacing incumbent iPlanet Application Server 6)
- New version of iPlanet Web Server installed (iWS 4.1 SP12)
thanks for your thoughts,
Owen

Hello,
Could you take a thread dump at that state?
kill -3 <pid of WLS>
Whats the state of the client application
- Exception (PeerGone, No Router)
- or just hangs
Also, you could run WLS using the JRE that ships with it. AFAIK, its v1.3.1_06.

Unable to Enable User Profile Disks in RDP server 2012R2

I am setting up a new Windows server that will act as an RDP server. The server has been built with Windows Server 2012R2.
I have the following roles and services working on the server: RD Web Access, RD Gateway, RD Licencing (with 30 user cal licences), the RD Connection broker, and the RD session host.
I have a SSL certificate configured and installed on the site, and both external and internal DNS are configured and working.
I have created and published an application collection and this is working. That is, when you go to https://remote.<servername>.org you are presented with a log in screen, users can log in with their domain accounts and then can connect to the published
applications, this is working both on our internal network and from the general internet.
So all the roles on the server are working and the collection itself is also working. However, what I cannot do is set it up so that we can use user profile disks with that collection. When I go through the Session Collection Wizard and I get to "User
Profile Disks" I can click on "Enable user profile disks" and then you can enter the options below.
I am entering the share location under location \\<servername>\<sharename>
I am using the default "store all user settings and data on the user profile disk"
Then I go to create the profile disks and I get the following error:
"Could not create the template VHD. Error Message: -2147024809
This has happened multiple times, I have done the following:
- installed all windows updates and rebooted the server, same error
- checked the share permissions AND the folder permission for that share, for testing purposes I have set permissions on both the folder and the share to allow full control to "everyone" (I also tried it with only "domain users") but
same error message.
- I have checked to see that no quotas are imposed on the disk where I am attempting to create the profile disks - this was because this was the closest thing I could find on Technet was this post:
https://social.technet.microsoft.com/Forums/windowsserver/ru-RU/aec30527-d742-42b9-950e-85c709c4cb45/vdi-problem-creating-user-profile-disks?forum=winserverhyperv
And that was a quota issue that I am not having.
The UPD wizard says the following "the servers in the collection must have full control permission on the user profile disk share and the current user must be a member of the local Administrators group on that server"
Both of those things are true.
I have attempted to search for that specific error message (-2147024809) and have found nothing on Technet or any other site.
I am hoping someone here has some thoughts. Thanks in advance.

I was looking at both the technet article for setting up UPD as well as this walk-through:
http://thewolfblog.com/2014/02/24/user-profile-disks-for-rds-2012-2012-r2/
The step after the creation of the disk in this walk-through is to look at who has permission on the .vhdx file, now obviously I am not at that step, but that is what led me down the trail of looking at user permissions, hence my attempts to set up shares
where 'everyone' has full permissions on both the share and the folder.
I have tried to set up multiple shares for the collection, I have tried on two different disks (volumes) on the RDP server itself, I also tried setting up a share on our fileserver (which has all kinds of shares working fine) and the same error occurred
in all cases.
I also found this Technet article:
https://social.technet.microsoft.com/Forums/windowsserver/en-US/d6469d31-6540-4075-a85f-a6e8f7c11e89/user-profile-disk-template-cannot-be-created-when-setting-up-session-collection?forum=winserverTS
So that seems close to what I am looking for, but I have checked and the exact group policy that was causing the above linked issue is not defined in our group policies, but maybe there are other group policies that are causing the issue?

i can no longer log into my ichat linked to my gmail. right after opening up ichat, receive the following message: lost connection with jabber. the server has unexpectedly disconnected. how to troubleshoot? thanks.

Hi,
There can be many reasons why the Login is "up the creek".
Any break in the network at your end whilst logged in will cause an issue.
A sort of discrepancy between what iChat thinks the state should be and what the server thinks.
If they don't agree the server will refuse to accept.
A Crash at the server end which does not log you out properly will also do it.
Any file at any time can be come corrupted.
Luckily with the iChat .plists they are recreated if removed with an iChat Restart.
If it were AIM you can also get your Account Suspended and this will not log you in.
(It tends to happen from Chat rooms where people notify AIM about bad behaviour (as they see it) and you have to apply to get Un-suspended).
Most of the big IM services use multiple servers.
Sometimes these go out of Sync.
In the case of AIM this happens when they remove Old unused Screen Names from people's Buddy List prior to making them available for re-registration. I am not sure if this happens at Google.
You seem to be talking about an account that has worked at Work and having new computer at home.
As I mentioned the Priority thing you have not said that it has coincided with the new computer logging in (this will kick the work Computer out of Google whether you are logged in on the Web Mail page or in iChat)
IN addition to that iChat stays partially logged in for Off Line IMs
This is done in the background by a support app called iChatAgent
If your Computer is ON but ichat is not started people can still send you Messages.
Instead of saving these on the server until you login iChat will start up.
Depending if the home Mac is effecting the Work Login it may be holding sway over your Login.
Using your girlfriend's login may have booted her Off Line where she normally uses the name/login.
The AIM Side can be specifically set to allow Multiple Logins and therefore NOT allow them. If this happens you get a warning and messages to do something about it.
You do not get these in any Jabber or Google Login as the Priority setting is supposed to take care of it.
If the Login works at the Web Mail Login and on one computer then the .plist on the work computer is the most likely issue.
There is a small chance that a Corrupt Buddy Pic (Home Folder/Library/Caches/com.apple.iChat/Pictures) may be the cause.
Set this folder to icon view and also use the Finder's View Menu > Show View Options and select icon view.
This should show all pics as their icon.
Check that all display properly.
At this point I would try a COMBO version update install of the last Update you did over what you have.
This often corrects hard to trace things

Migrating from SBS 2011 to Windows Server 2012R2 Standard with 365

Im looking to move SBS 2011 to Server 2012R2 standard and with a 365 migration as well.
Im thinking
BPA for AD (health check)
Add the Server2012R2 as a DC
Ensure replication
Move DHCP
Change DNS
Now this is where I get lost, now Im lost to use either dirsync or add essentials service, I have gone for standard and 30 cals with the option as I have 28 users and the essentials service would make everything quite nice for remote access and backups
etc.... however I don't know whether to just use dirsync with password replication instead ?
Currently Im aiming towards getting the dc up and running then enabling essentials on the dc but I dont know how it will effect SBS and having essentials on the same network and sync'ing people to the cloud ? So Should I use DirSync on a different server
instead to sync up to azure ?
Finally with 365 I have only ever done a migration involving an export of pst's from an exchange box and then on a new domain with new pc's and reimport the pst's on the user accounts in outlook.
However I have read when migrating to 365 was using exchange 2010 there was a application
to move everything across however you needed an ssl cert iirc ? so I dont know how it works now since the nice new dashboard upgrade (assuming the tool has been updated like dirsync)
along with the above how does AD now know where exahcnge if you use the migration app with an ssl cert and is it a case of still running the 365 config tool to configure each user to look at their mail in the
cloud ? Also is it a good idea to enable essentials from the start of the 2012r2 dc for replication top 365 or to use dirsync ?
then finally when replications is all good start transferring the FSMO roles over to the new DC and demote and remove the SBS server
I have seen (below) but i dont think it covers this scenario and I cant be the only person in this situation =\ ?

I’m a little confused with the description. Did you mean that set up DC (Windows Server 2012 Standard) and
then install the Windows Server Essentials Experience role? If so, when you migrate, please refer to the article:

Best practices for installing Win 10 under Hyper-V on Server 2012R2 host

Yeah, yeah, I know I could probably get my answers after spending 10 hours reading hundreds of isolated threads here. I've already put in about 2 hours, and I'm exhausted. Plus, this site does not have a very sophisticated search function.
I want to install Win10 as a VM on my Server 2012R2 machine. I am not currently hosting any other VMs, so my first decision was whether to try it using Hyper-V or VirtualBox. I started with VirtualBox, but I ran into two problems: networking
and video. Also, VirtualBox itself seems to have some issues with failing to install the extension pack. So now I think I'll give Hyper-V a shot.
I found some blog posts from last year providing guidance on setting up Hyper-V for Win10, but given the rate of change of this beta OS, I expect there are many new "features" that can be mitigated against by specific settings on the VM.
Some specific questions:
1. Generation 1 or Generation 2 in the Hyper-V setup? The blogs I've seen say to use Gen1, but provide no justification. Perhaps because they are using Win8 as the host? I am using 2012R2.
2. Does the Win10 ISO file need to be continually available to the VM, or is it only used in the initial installation?
3. How do I get the VM to access the GPU card, which has lots of memory, over the useless onboard video chip which only has 8MB and no 3D instruction set? This was a dealbreaker with VirtualBox.
4. I anticipate many issues with networking, but I'll start with this: I have dual onboard NICs going into a managed switch. Should I just give one physical NIC to the VM and let the host have the other? I think I'm going to have some issues
with DHCP IP address assignment, but we'll see. Any best practices here would be helpful.
Thanks.

>1.
I'd use Gen 1, that is a BIOS type boot, but that's just because I've had
less trouble than with Gen2 VM's.
>2.
Only during install, refresh, reset, or sfc.
>3.
No virtualization solution does it easily, but there is RemoteFX if you can
get a Windows 10 client to use it. I've never tried.
http://social.technet.microsoft.com/wiki/contents/articles/16652.remotefx-vgpu-setup-and-configuration-guide-for-windows-server-2012.aspx
>4.
That's what I would do (assigning one NIC to the VM, and one the host). If
both are receiving an IP address right now from DHCP, they will continue to
do so the new way unless you have a managed switch that would prevent more
IP addresses. It's hard to tell...

Questions in regards to server 2012R2 Remote desktop Service deployment and GPO

Hi Everyone
We have a business requirement moving to 2012R2 RDSH server. I have installed a 2012R2 member servers and enabled Remote desktop licensing role. I have activated the licenses. the servers is in operational
I have deployed 3 windows 2012R2 member server "RDS1" , "RDS2" and "RDS3".
on RDS1 I ran Add roles and Feature Wizard > Remote Desktop Services installation > Quick Start >Session based desktop deployment to complete the installation.
On RDS1 Server Manage Dashboard Page Select Remote Desktop Services > Overview. Under RD Licensing I added my 2012R2 license server "2012r2-tslic". Go to task. Edit deployment properties RD license mode to per device and click OK.
Reboot RDS1
Check RD Licensing Diagnoser everything is clear
On RDS2 I did the exact same thing ran Add roles and Feature Wizard > Remote Desktop Services installation > Quick Start >Session based desktop deployment to complete the installation.
But With RDS2 I move this server to an OU that link to a GPO with RD licensing details. after reboot the servers check RD Licensing Diagnoser I can see 2012r2-tslic specified as the license servers.
Based on this document
http://blogs.technet.com/b/askperf/archive/2013/09/20/rd-licensing-configuration-on-windows-server-2012.aspx Are you suppose to configure RD license server via Remote desktop Service deployment ? Not GPO ?
Here are my questions
We currently have ten 2008r2 terminal servers in a NLB cluster. each RDSH server have in house application installed on each one of them. User connect to the 2008R2 RDSH servers via RDP connection. we have a restricted GPO apply to those
RDSH servers. user cannot do anything on RDSH servers apart from running the application and use excel. On the remote desktop session host configuration we have enable settings like end a disconnected session , Active session limit ,
remote control users session , LPT port redirection.
We push out RD license server detail via GPO to the terminal servers
Can I use our existing GPO apply the licensing server settings , desktop restriction setting to the 2012R2 RDHS servers or we should be using Remote desktop Service deployment to do the job ? If that is the case how would you transfer the
current 2008r2 environment to 2012 using Remote desktop Service deployment. is that mean I have to manually configure 1 by 1.
Please help
Many thanks

Hi,
Please see my response to you in the other thread. Please contact me via email and I will go over the basic planning and deployment steps with you which will help clear things up and get you started off on the right foot.
You should only run through the wizard and create a RDS deployment once. Then you add the various servers (RDSH, RD Licensing, RD Gateway, etc), set Deployment properties, etc.
Thanks.

Hyper-V Role deployement with MDT2013 on a Server 2012R2 Trial Version

Hello,
when i deploy a custom image that i add the roles install Hyper-V, everything works fine, added the SkipRoles=Yes,
and the role Hyper-V is installed at the end of my new server 2012R2 Trial version, HOWEVER,
there's no icon that appears on the desktop, on the manager, the Hyper-V Manager option is not there,
all the Hyper-V related services are installed.
Seems there's a GUI issue, however in server manager the roles appear on the left side
I reboot, and yet nothing appears, i uninstall the Hyper-V role manually, reboot, re-install manually and the missing shortcuts appear.
Can someone provide me a hint to fix this, i've tested other roles and they also don't appear (DNS).
Thanks in advance for your replys

You are talking about two different things here. The Hyper-V Core, and the Hyper-V Tools. It appears that you want both. Run the following command:
dism.exe /online /get-features
and verify that all hyper-v components are installed:
Feature Name : Microsoft-Hyper-V
State : Enabled
Feature Name : Microsoft-Hyper-V-Offline
State : Enabled
Feature Name : Microsoft-Hyper-V-Online
State : Enabled
Feature Name : RSAT-Hyper-V-Tools-Feature
State : Enabled
Feature Name : Microsoft-Hyper-V-Management-Clients

Feature Name : Microsoft-Hyper-V-Management-PowerShell
