I have a windows server 2003 as a PDC ("server 1"). I am attempting to take it offline once I get several issues cleared up. I have two other windows server 2008 servers that have been promoted as DC's ("server 2" and "server 3").
When I run dcdiag on any of the servers I get failed connectivity to "server 2" and "server 3"
the host guid._msdcs.domain could not be resolved to
an ip address...although the guid dns name couldnt
be resolved, the server name resolved to the ip address.
Check that the ip address is registered correctly with
the dns server. "server 2" failed test connectivity.
While there could be several issues preventing replication, I noticed one thing on the pdc ("server 1"). In DNS under the msdcs folder there is an "" folder (along with "dc", "domains", "gc" and "pdc". The "_" folder references "server 2" with the guid thats referenced in the dcdiag connectivity failure.
What does the "_" folder represent? Is that where my problems begin? The pdc has the wrong guid for "Server 2". I need to be able to replicate to "server 2" and "server 3"
