All of a sudden yesterday we could no longer open the Exchange Management Console to administer mail. It is telling up that it cannot find a Domain Controller. I started poking and finding that we have a major issue and I don’t know what happend and I cannot seem to fix it no matter what I do… I think that something is screwed up royally! Here is my netdiag and dcdiag… My DNS looks different but I don’t have anything to compare it to… I think that somehow we are missing parts of the tree that I remember seeing there before. I think that they were like _tcp.domian.com/_udp.domain.com something to that effect.
PLEASE HELP!
DCDIAG – I have replaced the domain and server names… I am running W2K3 x64 Standard. This machine is a DC and running as the GC and DNS/WINS server. I have a 2nd DNS/WINS server on a DC2.
Testing server: Default-First-Site-Name\CSCIDC1
Starting test: Connectivity
* Active Directory LDAP Services Check
The host 7fa4e31d-89d1-40be-b210-c68c2a276603._msdcs.domainname.com could
not be resolved to an
IP address. Check the DNS server, DHCP, server name, etc
Although the Guid DNS name
(7fa4e31d-89d1-40be-b210-c68c2a276603._msdcs.domainname.com) couldn’t be
resolved, the server name (cscidc1.domainname.com) resolved to the IP
address (x.x.x.x) and was pingable. Check that the IP address is
registered correctly with the DNS server.

Doing primary tests
Testing server: Default-First-Site-Name\servername
Skipping all tests, because server servername is
not responding to directory service requests
Netdiag:

[FATAL] No DNS servers have the DNS records for this DC registered.
I have done everything that I can find on the internet. I have stopped the netlogon and restarted. I have stopped and renamed the netlogon.dns file and restarted. I have tried the netdiag /fix and dcdiag /v/fix. I am at a complete and entire loss at this time!!!!!
