Server 2012: Enabling replication hangs

Hello All,
I have setup replication between 2 Hyper-V 2012 server clusters. When enabling the replication of a VM, everything looks fine. The Replica Server is found. All settings are correct and the replica server is reachable over the used tcp port.
When I click finish, I see a progress bar, stating "Enabling Replication..." which never disappears. Only when hitting Alt-F4, the bar disappears, but then I'll get back to the wizard.
It doesn't matter what setting a set for initial replication.
How can I troubleshoot this?
You know you're an engineer when you have no life and can prove it mathematically

A thing to note: Replication is actually working. It's only the interface that keeps hanging. When pressing Alt-F4, the Enabling Replication progress bar disappears and replication is setup. The initial replication than has to be started. This results
in a similar hanging progress bar. But once again Alt-F4 and the initial replication is setup also!

Server 2012: Enabling Hyper-V Replica Site to Site Failure

We recently installed Server 2012 Data Center with Hyper-V on a two servers at two different sites: Main Site and DR Site.
Hyper-V is enabled and working great at both sites on these servers and now trying to configure Hyper-V replica gets us this result:
Some of the items we made sure to verify:
Enabled Firewall rules for inbound rules on Port 80. (Hyper-V Replica HTTP Listener) (Both Sites)
Modified ASA Firewall for HTTP port 80 and can run a packet trace from site to site.
Ping works fine in communication between servers
Both are in the same domain
Within the same Trust Group
Same default storage location and can view the folder from each location
So I am not sure what we are missing, but is there another port that needs to be open if we are going through HTTP because after starting to configuring the replica another message shows that "Could not get the configuration details of the specified server."
Searching around on TechNet didn't show any resolution for this, but if anyone would have some additional tips to try to troubleshoot that would be greatly appreciated!
Thank you!

SQL Server 2012 Transactional Replication with updateable subscriptioins

Hi All,
It is heard that Transactional Replication with Updateable Subscriptions
is
deprecated in SQL 2012 so it is not possible to configure through the wizards but
we can still configure it by using T-SQL Script. Would you please share that script if possible to configure the same in SQL Server 2012. Thank You.

Windows server 2012 R2 replication

Hi all,
I have windows server 2012 standard edition and Recently I rented a new dedicated server from the data center. My new dedicated server has Windows server 2012 R2 standard edition. The problem is when I am doing a replication from windows server 2012 standard
to windows server 2012 r2 standard I do not see SYSVOL share in my windows server 2012 R2 standard. I see all the active directory users have been replicated but not the share.
How can I solve this issue? Anyone can help me with this?

Hello,
seems for me that the Promotion from the new DC didn't went well. In your case remove the new machine from the domain, disconnect and use dcpromo /forceremoval and run metadata cleanup on the Windows server 2012 DC.
http://msmvps.com/blogs/mweber/archive/2010/05/16/active-directory-metadata-cleanup.aspx
Tthen assure that you use ONLY the existing DC/DNS server on the NIC from the new machine, NONE else, even not if this machine should become DNS server role, and run dcpromo again to join it to the exiting domain.
So the schema was upgraded to version 69 as Windows server 2012R2 requires this?

Windows server 2012 File replication

Hi All,
I am SQL DBA. But in my current company I am having a new responsibility called IIS Admin.
In my organization, I am instructed to do following activity.
There is a Live Web server(named X) and a user acceptance test Server(named Y)
There is a folder called "Intranet" in both the servers.
If any changes done in "Intranet" of X(any new files created, updated or deleted.....) it needs to be automatically updated on "Intranet" of Y also. But not Vice versa, it should be one way.
At the same time, we need to do changes on Y also.
Both the servers are installed with windows server 2012(Standard edition).
What mechanism can we use to achieve the above.
Please help me in the regard.
Thanks & Regards,
K.P.Senthil Kumar

Hi,
For the file replication, you could use DFS Replication.

Windows Server 2012 enable memory Turbo boost

Hello guys.
I have a Sony Vaio VPC-F113FX notebook with Quad Core Intel i7 processor with 8GB of RAM.
It is installed a Windows Server 2012 Standard.
I bought an SD card of 64 GB and intended to use the Turbo Boost feature in memory, only this option is not displayed in the properties of the operating system memory card. Can you help me configure or enable this feature in Windows Server 2012.
Thanks
Obrigado por contactar o fórum Microsoft Technet!

Hi Hezequias,
Thanks for posting.The Turbo Boost feature is just provide by Intel can cab be obly used on the Intel i5 and Intel i7.
As you mentioned that you used a 64GB SD card and intended to use the Turbo Boost feature, so I guess you might talked about the Ready Boost.
Ready Boost is a feature provide by Microsoft, Ready Boost is a disk caching software component which allows any compatible mass storage device to be used as a hard-drive memory cache for the purpose of increasing random read access
speed to the hard drive. Potentially compatible ReadyBoost devices include USB flash drives, flash memory,solid-state drivers(SSDs), and SD cards. There is a limitation of 32 GB per ReadyBoost device.
However the Ready Boot feature was just supported by the Microsoft Clients(such as windows 7) but not the server edition.
So the feature can't be used on windows server 2012 standard operation system.
Hope it helps.
If you have any concerns, feel free to post back.
Best Regards,
Elaine

SCVMM service causeing Windows Server 2012 R2 to hang at "Please Wait"

I have a problem with the VMM service causing my server to no longer boot. I have a Windows Server 2012 R2 server running on Hyper-V that has only SCVMM installed on it, I was getting ready to install SCCM on it after I finished migrating the machines to
a new hard drive. After I moved the VM's all of them ran fine except the server with VMM on it, I spent plenty of time on Bing and Google trying to find out why my server was stuck at Please Wait and I found nothing, not one thing. I eventually disabled the
SCVMM services in msconfig from safe mode and now it boots fine.
It cant be because I moved it because I had a previous VM that was my WSUS, Essentials, RRAS, RDGW and one i installed VMM on it and rebooted the same happened.
This did not happed when I was setting this up at my other deployment for another company

I think have fixed it, I set it as disabled as I updated VMM to Update Rollout 1 and 2 and applying the changes described in the update description. Then once complete I set the service as Automatic (Delayed Start).
If anyone else has this issue pleases share your experiences here.
Now its has returned, not this sever only has VMM 2012 R2 (with all updates) and only that no other services

Hyper-V hangs forever at Server 2012 reboot

When I reboot the host OS (Dell server), it tries to shut down the VM. There is a single VM running server 2012 with Exchange set up. The reboot process hangs for about an hour with the screen showing "Shutting down service: Hyper-V Virtual Machine
Management". The activity indicator circle continues to go around.
I've noticed a couple other weird things this past week. When trying to load up wbadmin (host) to see the status of the last scheduled Windows Server Backup job, MMC just sit's there for hours "loading data". I have to manually kill it. I also
am unable to uninstall anything. It sit's in the "calculating disk size" stage and I have to manually kill the process.
I ran a SFC and it found and corrected a corrupted file(s). I wanted to see what people thought could be causing this super-long reboot process. Server has 32gb ram, 16 of which assigned to the Exchange VM. No line of business app's, no SQL or other apps.
It's an incredibly simple domain with 8 users.
The only complication is that the Exchange VM is set up to replicate to another machine that is running Hyper-V Server as the host OS. This replication has been problematic, requiring me to manually sync is several times. But the connection is solid, via
a cat5e cable in the same room as the primary server (till the off-site office and a VPN is ready to hold the secondary server).

Hi RedRules,
I don’t found the similar issue, base on my experience, it most possible may your disk corrected, Could you try
to move the vm to another drive and confirm there don’t have the corrupted block on your disk.
You can refer the following related thread to do the disk check:

CRM 2015 installation hangs without errors on Windows Server 2012 installed in a VM

I have installed a Windows Server 2012 and SQL Server 2012 on a VM using VMware Player and then installed Dynamics CRM 2013, working out all the configuration problems.
The installation hanged once without errors and when I tried it again it was installed, no problems. Dynamics CRM 2013 works without issue.
Then I copied the machine, uninstalled the Dynamics CRM 2013 and started installing CRM 2015. However this time without errors the installation hangs even though I tried more than 5 times.
There are no errors, installation program is not unresponsive and task manager shows nothing out of the ordinary.
I have also tried this on multiple physical and virtual PCs to no avail.

Try to Delete the registry files of CRM before you start the installation : HKEY_LOCAL_MACHINESOFTWAREMicrosoftMSCRM

Enabling network discovery on Windows Server 2012 R2

Good afternoon.
As per the title, I have set-up a new server at work. The server is running no problem but none of the other computers connected to the network can 'see' the new server. I've gone into the control panel and tried to turn on the network discovery, but it just
defaults back to 'off'.
I did so a search on here first before troubling anyone and I did find this answer :
Thanks for the post.
I did some research and found this issue may occur if the dependency services are disabled. Please make sure the following services are enabled and running.
- SSDP Discovery
- UPnP Device Host
Disabling Network Discovery/Network Resources"
That may well be the answer, but unfortunately that means absolutely nothing to me.
Is someone able to help me try and switch this on, but by offering an explanation an 'idiot' would understand.
Thanks in advance.

Hi,
This issue occurs for one of the following reasons:
•The dependency services for Network Discovery are not running.
•The Windows firewall or other firewalls do not allow Network Discovery.
To resolve the issue, follow these steps:
1.Make sure that the following dependency services are started:
DNS Client
Function Discovery Resource Publication
SSDP Discovery
UPnP Device Host
2.Configure the Windows firewall to allow Network Discovery. To do this, follow these steps:
Open Control Panel, click System and Security, and then click Windows Firewall.
In the left pane, click Allow an app or feature through Windows Firewall if you are running Windows Server 2012. Or, click Allow a program or feature through Windows Firewall if you are running Windows Server 2008 or Windows Server 2008 R2.
Click Change settings. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
Select Network discovery, and then click OK.
3.Configure other firewalls in the network to allow Network Discovery.
4.Turn on Network Discovery in Network and Sharing Center

SQL Server Compact 3.5 Merge Replication With SQL Server 2012 - Causing IIS App Pool to Crash

Hi, I may be the only person in the world doing this but I wanted to give this information to anyone else who may follow this path in the future, and hopefully avoid a headache, or at least a paid support call to Microsoft.
My original scenario was we had a SQL Server 2008 Server using Merge Replication through and IIS (web server) to several Windows Mobile 6 devices. This has worked fairly well for a few years.
Recently we upgraded our SQL server to version 2012 SP 1. After moving the database over to the new server, and re-setting the merge replication stuff, we couldn't get merge replication to work on the Windows Mobile 6 handheld devices. The replication
would appear to start, and then we would get a message saying that the device could not get to the web site. The message on the handheld device was this:
"The IIS service is not available."
After doing some more research, we found that the start of the replication process was causing the Thread Pool that was running the SQLCESA35.dll to crash.
The SQLCESALOG.txt file had this information:
Date Time == SQLCESA Version ==> 3.5.8088.0
Date Time Hr=80004005 ERR:Couldn't find existing RSCB 1
After 2 days of trying to figure out the issue on our own, we gave in and called for paid Microsoft support. They eventually found a known issue where a cumulative update was able to fix the problem.
We installed the update on the IIS server and everything ran smoothly again.

Unable to add replication feature in sql server 2012 web edition

Hi All,
We are using SQL Server 2012, Web edition and when it was installed replication is not an added feature so I tried to add this feature but getting below error.
Error: There are no SQL Server instances or shared features that can be updated on this computer.
Description: The version of SQL Server instance MSSQLSERVER does not match the version expected by the SQL Server update. The installed SQL Server product version is 11.1.3000.0, and the expected SQL Server version is 11.0.2100.60
And also please let me know how to identify the default file location of the setup file 'setup.exe' for SQL Server 2012 (Webedition, 64bit) Grateful to your time and support.
I'm using "C:\Program Files\Microsoft SQL Server\110\Setup Bootstrap\Update Cache\KB2777772\QFE\setup.exe" to add replication feature, please correct me if I'm wrong.
Thank You.
Regards,
Kalyan
----Learners Curiosity Never Ends----

It looks like you are trying to add Replication Components, however, you are using the Cumulative update package 5 setup, which is wrong.
Note that you will not find the setup file for SQL Server on your file system, it will be on your installation media.
To install SQL Server Replication Components, locate your installation media and run Setup.exe. Select the add features to an existing instance option, select your instance, and add replication components.

Enable more than two concurrent sessions in Server 2012 r2

Hello,
I have setup RDS on Server 2012 R2 with the following roles: (RD Connection Broker, RD Session Host, RD Gateway, RD Licensing, RD Web Access). My sole purpose for this setup was to enable this server and only this server to allow more than 2
concurrent RDP connections.
Here is some background information:
1. I will not be using RemoteApps or the Web access, I only only need to RDP into this server with more than 2 concurrent connections.
2. The licensing server is activated and I have a 50 user CAL installed on it. It has issued licenses to 3 users that have logged into the server while I was looking at the Web site features. So I know the licensing is working properly.
3. This server does reside in a domain but I'm looking to have everything self contained on just the one box. I do not want to put anything on my domain controller or a separate machine.
4. Everything looks to be fully configured in all of the roles. I have no warnings about things not being configured correctly.
5. When I attempt to login with a 3rd user to this system, it still prompts to have me remove one of the previous 2 sessions.
I know I must be looking right past the setting or it is in a very convoluted space, but how do I enable this server to allow more than 2 RDP sessions? I've made the change in group policy for (Administrative Templates\Windows Components\Remote Desktop
Services\Remote Desktop Session Host\Connections\Limit number of connections) to 50 but this still not seem to correct the problem.
Thanks for any answers you can provide,
Fred Levario

Hi Fred,
Thank you for posting in Windows Server Forum.
Are you working with Domain or Workgroup environment?
Because from your description seems you want everything on single server. To enable more than 2 RDP session for your server we need to Add RD Session Host and RD Licensing Role Services, configure the RD Licensing mode, and licensing server name in the local
group policy, Activate the RD Licensing server and install RDS CALs using RD Licensing Manager.
You can configure the Licensing mode and licensing server through GPO as per below path.
Computer Configuration\ Administrative Templates\ Windows Components\ Remote Desktop Services\ Remote Desktop Session Host\ Licensing
Use the specified Remote Desktop license servers - Provide the FQDN of the license servers to use
Set the Remote Desktop licensing mode - Specify the ‘per user’ or ‘per device’ licensing types
More information.

BSOD on Server 2012 running dfs namespace and dfs replication roles with deduplication

Hello,
I have recently setup 2 dfsn & dfsr servers, both 2012 one physical the other virtual.
The idea is to have one server as primary and the other as a failover \ DR.
The primary server is virtual and connects via mpio \ iscsi to a dell san, using the provided dell DSM Drivers.
The secondary server is physical with local disk for storage.
I copy files to a namespace setup to always prefer the primary server, these files are then replicated across to the secondary.
I have also turned on deduplication on both servers to get the most out of the available storage.
This has been working well for 6 months or so, there have however been 2-3 occasions where the primary virtual server has crashed and blue screened causing the DFSR database to undergo a full consistency check.
The bug check errors i have managed to extract from the Memory.dmp and mini dump are as follows:
*                        Bugcheck Analysis
REFERENCE_BY_POINTER (18)
Arguments:
Arg1: 0000000000000000, Object type of the object whose reference count is being lowered
Arg2: fffffa80379a3070, Object whose reference count is being lowered
Arg3: 0000000000000002, Reserved
Arg4: ffffffffffffffff, Reserved
   The reference count of an object is illegal for the current state of the object.
   Each time a driver uses a pointer to an object the driver calls a kernel routine
   to increment the reference count of the object. When the driver is done with the
   pointer the driver calls another kernel routine to decrement the reference count.
   Drivers must match calls to the increment and decrement routines. This bugcheck
   can occur because an object's reference count goes to zero while there are still
   open handles to the object, in which case the fourth parameter indicates the number
   of opened handles. It may also occur when the object?s reference count drops below zero
   whether or not there are open handles to the object, and in that case the fourth parameter
   contains the actual value of the pointer references count.

I have searched for others having a similar problem but have not managed to find much.
The memory dump at the time of the crash does seem to hint at a problem with DFSR.exe.
The setup seems to be running fine again now and is going through its consistency checks, it is just a major inconvenience and will only get worse as the DFS becomes busier and approaches capacity.
The plan was to put this setup into production however with the unpredictability of blue screen reboots I cannot see this happening until I can find a fix or work around.
I have yet to see this problem occur on the other (physical) server, this is pretty much identical in configuration apart from its storage access.
My thoughts are a possible bug in the DFSR component or a bug in the DSM Drivers used for the iSCSI SAN connection or maybe a combination of the two.
Any help, thoughts or suggestions greatly appreciated
Thanks

Hi,
Please install the current version of Dfssvc.exe Dfsc.sys Dfsrs.exe for Windows Server 2012.

The issue may be due to the DFSRoot folder has lost NTFS permission. Some reasons why DFS root lose ACLs Links are listed in the article below:
How to implement Windows Server 2003 Access-based Enumeration in a DFS environment
http://support.microsoft.com/kb/907458/en-us
You could use dfsutil to set NTFS permission: dfsutil property ACL \\DFS-namespace

To narrow down the issue, you could remove the DFS role to check if the issue related to the dfs namespace and dfs replication roles.

0x8056530b error enabling disk deduplication on Windows Server 2012 R2 Volume - any ideas why or how to fix?

I'm getting the following error when trying to enable disk de-duplication on a volume on my Windows 2012 R2 file server. The error is:
"There was an error updating Data Deduplication on volume: MSFT_DedupVolume.Volume='\\?\Volume{8dfc4322-9997-11e3-93f5-005056a84b9b}\' - HRESULT 0x8056530b, The specified volume type is not supported. Deduplication is supported on fixed, write-enabled
NTFS data volumes and CSV backed by NTFS data volumes."
The volume in question is a 1TB VMFS volume mounted to the virtual machine that is the Windows file server. I could find no info anywhere that references this error as it relates to a standard mounted volume or VMware or VMFS.
Any ideas on what could be the problem or how to fix it? I could find nothing in the log files other than an entry which is basically a repeat of the error above.
Any help would be greatly appreciated.

P.S. This is a volume that was previously mounted on an older Windows 2003 server. Not sure if that may make a difference.

have you compared this issue to the ones that are successful and compared what is different?
Have you made sure of the following:
Servers
See the following list for server requirements for deduplication:
• Server hardware should meet the minimum requirements for running Windows Server 2012. The deduplication feature was designed to support minimal configurations such as a single processor system with 4 GB of RAM and one SATA hard disk drive.
• If you plan to support deduplication on multiple volumes on the same server, you need to plan an appropriately size for the system to ensure that it can process the data. The general rule is that the server needs 1 CPU-core and 350 MB of free memory to run a deduplication job on a single volume, and that job can process about 100 GB per hour or around 2 TB per day. Deduplication scales with additional CPU core processors and available memory to enable parallel processing of multiple volumes.
For example: If you have a server with 16 CPU core processors and 16 GB of memory, deduplication uses 25% of the system memory in the default Background Processing mode, and in this case, that would be 4 GB. If you divide by 350 MB, you can calculate that the server could process about 11 volumes at a time. If you add 8 GB of memory, the system could process 17 volumes at a time. If you set an optimization job to run in Throughput mode, the system will use up to 50% of the system’s memory for the optimization job.
• Data Deduplication supports up to 90 volumes at a time; however, deduplication can simultaneously process one volume per physical CPU core processor plus one. Hyper-threading does not impact this because only physical core processors can be used to process a volume. A system with 16 CPU core processors and 90 volumes will process 17 volumes at a time until all 90 volumes are done, if there is sufficient memory.
• Virtual server instances should follow the same guidance as physical hardware regarding server resources.
Volumes
Volumes that are candidates for deduplication must conform to the following requirements:
• Must not be a system or boot volume. Deduplication is not supported on operating system volumes.
• Can be partitioned as a master boot record (MBR) or a GUID Partition Table (GPT), and must be formatted using the NTFS file system.
• Can reside on shared storage, such as storage that uses a Fibre Channel or an SAS array, or when an iSCSI SAN and Windows Failover Clustering is fully supported.
• Do not rely on Cluster Shared Volumes (CSVs). You can access data if a deduplication-enabled volume is converted to a CSV, but you cannot continue to process files for deduplication.
• Do not rely on the Microsoft Resilient File System (ReFS).
• Can’t be larger than 64 TB in size.
• Must be exposed to the operating system as non-removable drives. Remotely-mapped drives are not supported.
Note
Files with extended attributes, encrypted files, files smaller than 32 KB, and reparse point files are not processed by deduplication.
