Exchange 2003 will not use local 2008 DC for GC/DC
Posted on 2008-10-17
Just installed Server 2008 DC/GC into my 2003 AD network, it is on the same LAN as a 2003 DC and a single Exchange 2003 server. The issue is that the Exchange server will not detect the 2008 server as a GC or DC. It will find the 2003 server, but if that server is shutdown it will go outside the LAN and detect remote location DC's.
Items checked thus far;
-2008 Firewall disabled
-DNS is running correctly and Exchange is pointed at the 2008 server.
-Hard coded Exchange with the 2008 server (after reboot this caused exchange to be unresonsive, as if the GC/DC was not even present)
-No interesting error logs on either server
Any Ideas what I'm missing? It's as if the 2008 server is not a DC.
