Consider the following scenario:
- You deploy a Group Chat server in a Microsoft Office Communications Server 2007 R2 environment.
- You add a Distribution Group (DG) as a member to a Group Chat room in the environment.
- A user in the DG signs in to the Office Communications Server 2007 R2 Group Chat client.
This issue occurs because it takes longer than expected for the Group Chat server to synchronize with Active Directory Domain Services (AD DS).
