Error: This computer could not locate a domain controller for the Active Directory domain displayed in the error message because the Domain Name System (DNS) servers used by this computer for name resolution failed to look up the service (SRV) resource record.
Cause: The DNS SRV resource record is not registered in DNS.
Solution: Verify that the SRV resource record for the requested domain and service type exists in DNS. You can do this using the Dcdiag command-line tool, which must be run on a domain controller for the Active Directory domain you entered. To download Dcdiag, see the Download Center on the Microsoft Web site(go to http://www.microsoft.com/ and search for "download center.").
Cause: One or more of the zones listed in the error message do not include a delegation to its child zone.
Solution: Verify DNS zone delegations by using the Nslookup command-line tool.

Tried downloading dcdiag to the domain controller, it seemed to execute in a DOS window, and then closed, so I haven't made any progress in solving the problem. Any help is much appreciated.
Second question: how difficult is it to change the name of a domain. Thanks again!
