SYMPTOMS

After you restart a computer that is running Microsoft Office Communications Server 2007 R2 Group Chat Server, the Group Chat service does not start. This occurs when the Channel Server (mgcchans) or the Compliance Server (mgccompl) tries to start before Microsoft Message Queuing starts. However, the Channel Server cannot function without Message Queuing. Therefore, the Group Chat service does not start.

WORKAROUND

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MGCCHANS]
    "DependOnService"=hex(7):6d,00,73,00,6d,00,71,00,00,00,00,00
    
  3. On the File menu, click Save As.
