We seem to be having a problem with the SCCM remote tool disconnecting, but only with Windows 8.1 clients.  Windows 7 clients seem to work fine.  It will connect, and then after about 20 seconds or so disconnect and then bring the user to the lock screen.  Has anyone experienced this behavior before? We are fully patched to CU3 on the client and console ends. It would appear to be an authentication issue, but the strange part is that it does make the initial connection without difficulty. All other aspects of management like advertisements, software pushes, updates, etc. work just fine.

Thanks.

Hi,

Have you checked CMRcViewer.log(Path:%temp%)?

You could also check the similar thread below that related to Group Policy.

Joyce,

After looking at that log, I seem to have found the offending error.

[WT_CompleteIO failed. Network shutdown : Unknown error (Error: C0000120; Source: Unknown)

After googling this issue, it seems that there are certain User Policies that cause this problem.

http://support.microsoft.com/kb/2716965

Unfortunately, none of those are set in our environment and are all set to Not Configured.  If you have any more insight, that would be great.

Thanks.

Hi,

Have you checked the Computer Policies as the link I posted above?

Best Regards,

Joyce

Joyce,

That is correct, that policy is also set to Not Configured.

Thanks

Hi,

>>Windows 7 clients seem to work fine. 

Does the Windows 7 clients have the same environment settings with the Windows 8.1 clients? All the Windows 8.1 clients have the same error?

Best Regards,

Joyce

Joyce,

That is correct.  All Windows 7 and Windows 8.1 clients are pulling the same group policies and on the same domain.  Connecting to any Windows 8.1 client produces the same error.

Thanks.

Hi ,

Are you running SCCM 2012 or SCCM 2012 SP1? Windows 8.1 client is not supported by SCCM 2012 without SP1. (https://technet.microsoft.com/en-us/library/gg682077.aspx#BKMK_SupConfigClientOS)

If you are running SCCM 2012 SP1, check the RDP setting on the Windows 8.1 clients. The remote control is likely a shadowed RDP session.
1.Apply the latest hotfix of RDP client components on Windows 8.1 client.

2. Check the RDP related group policies (Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Device and Resource Redirection) and registry key (HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services). Compared it to a working one and see if there is any difference. 

3. Collect a netmon trace when the issue occurs will help address the network issue.

Thanks. 

Joyce,

1.  We are running SCCM 2012 R2 with CU3 so this should be moot, correct?

2.  I've compared the policies in both the group policy object editor and RSOP on both our Windows 7 and Windows 8.1 computers and they are identical.

3.  I've successfully captured a netmon trace during sccm remote disconnect and see the traffic coming from CmRCViewer.exe and eventually see it stop, but have no idea how to interpret these logs.

Thanks.

Hi ,

Yes, Windows 8.1 client is supported by SCCM 2012 R2. Please let me know the OS version of SCCM 2012 R2. Apply the hotfixes for the SCCM 2012 R2 OS.

Available updates for Remote Desktop Services in Windows Server 2012
http://support.microsoft.com/kb/2821526

For Windows Server 2008 R2 Remote Desktop Services updates, please see KB2601888.
For Windows Server 2012 R2 Remote Desktop Services updates, please see KB2933664.

I also suggest update the latest NIC driver for the Windows 8.1 client, especially if the NIC driver is out-of-dated.

The remote control use TCP port 2701. You can check the netmon to see if there is clue about this.

All,

I know it's been a while, but just wanted to let everyone know what happened with this.

So I used this as a guide to move our existing SCCM 2012 R2 environment/database on the 2008 R2 server that it was on to a 2012 R2 Server (thanks grundlichkeit) in hopes that it would fix it.

This still did not fix the issue, but at least forced me to do something that I've been wanting to do for a while.

I finally broke down and put in a support ticket with MS about it.  In less than five minutes, it was pointed out to me that remote control viewer isn't supported on anything past Windows 7/Server 2008 R2

At least I know that I'm not going crazy now.

Thanks everyone.
