I'm attempting to install Exchange on a new 2003 server. It's not the DC. One of the steps to set it up is to run a network test. I ran DCdiag on our server andits coming back that it can't resolve the IP. Here's what i'm getting. All windows 2003 servers here, and our DC is also our DNS server.
Domain Controller Diagnosis
Performing initial setup:
Done gathering initial info.
Doing initial required tests
Testing server : Default-First-Site-Name-\domainserver
The host xxxxxxxxxxx-xxxxxx-xxxxxxxxxxc.msdcs.selhs.org could not be resolved to an IP address. Check the DNS server, DHCP, server name etc.
Although the Guid DNS name (xxxxxxxxx-xxxxx-xxxxx.msdcs,sekhs,irg) couldn't be resolved, the server name (domainserv.selhs.org) resolved to the IP address (10.0.0.12) and was pingable. Check that the IP address is registered correctly with the DNS server.
