Our server 2003 domain controller has crashed and now outlook can't connect to our exchange 2007 server. The exchange server boots and I can login to the server and open EMC and everything. We have 2 server 2008 domain controllers, I've manually pointed to another DC in EMC but still users cannot connect. We don't have another 2003 server in our domain. I've read that exchange 2007 requires a 2003 domain controller, can you guys confirm this and what are my options to getting connectivity back to the users?
