OCS 2007 R2 Server Loses network connection on Server Startup

Posted by Mino on May 13, 2009

As strange as this might sound to you but this is the latest case I have faced which in the end appeared to be a known bug and Microsoft Premiere Support were able to solve it after 3 weeks of investigation

Setup

So you have OCS 2007 R2 implemented over Windows 2008 and the Backend is placed on SQL 2008 on windows 2008 server. The below roles are all implemented on windows 2008:

  • Front End 1
  • Front End 2
  • Mediation
  • Consolidated Edge not joined to the domain

Problem:

When you restart any OCS server you cannot remote access to that server again, the Ping over the server is lost and when you go and check the server you find the network is disconnected.

If you went through all of the OCS Server services you will find them all are in the mood of starting and it will take it like 10 minutes then it will fail to start .

If you set these OCS Services to manual start rather than Automatic then reboot. You will find that the server is functioning normally.

This is really a very strange problem and I never faced it before as I have already implemented the OCS on 2008 but I still up to this moment don’t know the symptoms that causes this problem to happen.

Solution:

– Set startup type for wmiApSrv to automatic

– Add dependency on RtcSrv to wmiApSrv

– Set startup type for RtcSrv to automatic

– Reboot

– RtcSrv is starting and running

– Set startup type for all Rtc* services to automatic

– Reboot

– All Rtc* services starting and running

 

To set the RTCSrv service dependency you can use the registry to modify the following:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RtcSrv and modify the DependOnService to include the wmiApSrv.
