November 30, 2012

Perform the steps in this procedure only if you change the hostname or IP address on a IM and Presence server that was previously integrated with Microsoft LCS/OCS. You need to do this to ensure the Microsoft Office Communicator (MOC) server and clients reflect the correct IM and Presence IP address and hostname (after your changes) and the new FQDN.

Before You Begin

Complete the Post-Change Task List.
