Removing server roles from OCS 2007 R2 servers

Unfortunately, if you follow the instructions here (http://technet.microsoft.com/en-us/library/dd572507(office.13).aspx) to the letter, you’ll get an error when you try to remove the Core Components.

The OCS Admin Tools are not listed in the removal order, and unfortunately will prevent you removing the Core role. So, where it says this….

If you are removing an Edge Server, a Mediation Server, an Archiving Server, or a Monitoring Server, remove the Office Communications Server 2007 R2 components in the following sequence:

• Microsoft Office Communications Server 2007 R2, Edge Server
• Microsoft Office Communications Server 2007 R2, Mediation Server
• Microsoft Office Communications Server 2007 R2, Archiving Server
• Microsoft Office Communications Server 2007 R2, Monitoring Server
• Microsoft Office Communications Server 2007 R2, Core Components
• Microsoft Office Communications Server 2007 R2, Unified Communications Managed API 2.0 Core Redistribution package
