I moved my Domain Controller to a new box, the old server is still intact. The problem I'm having is that the email server will not pickup the new server. The Exchange box is Server 2008/Exchange 2007. How do I get the Exchange to see the new domain controller. I set the new server with the fsmo roles, DNS, DHCP, Global Catalog. The exchange server is pointing to the new server, DNS. I can ping the server name, the mailbox's just wont open. Any suggestions.. Exchange 2003 would pick the change right up, I thought it would be the same. I right clicked the Oraganization Config, Server Config, Recipient Config, and set the Changed the DC name. Still nothing.
