The Channel service stops when a user signs in to a Group Chat client in Office Communications Server 2007 R2 Group Chat

Symptoms

Consider the following scenario:
  • You set up a Group Chat server pool that contains several Group Chat servers in a Microsoft Office Communications Server 2007 R2 environment.
  • You configure the log level for the Channel service to Debug or Trace.
  • A user signs in to a Group Chat client.
In this scenario, the Channel service on the last started Group Chat Server in the Group Chat server pool stops.

Cause

This issue occurs because an object reference in a Group Chat function is set to a NULL when the function tries to determine whether the client is local or remote. This causes the Channel service to exit when the logging is set to a DEBUG level or a higher level.
