We are in the process of removing a 2000 domain controller from our network. We have moved all FSMO roles to our PDC emulator. We are prepared to demote the server but our implementation of Exchange 2003 has hooks into the old server.
In Exchange 2003 how to I ensure that Exchange does not communicate with the DC we plan on removing? In the Properties window for the Exchange server I observed the problem server under the Directory Access tab. There are multiple DCs and GCs listed but when I highlight the problem server the Add and Remove buttons at the bottom remain greyed out?
