I have a 2 server Active Directory network... the administrator profile became corrupt on one of the servers... I had to recreate....I have been getting the message above ever since....AD works, just intermitent problems.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Doing initial required tests

   Testing server: Default-First-Site-Name\MYSERVER
      Starting test: Connectivity
         The host f7bf16c6-6dee-47e1-98f3-75b38db59d4c._msdcs.mydomain.com could not be resolved to an IP address.  Check the DNS server, DHCP, server name, etc
         Although the Guid DNS name
         (f7bf16c6-6dee-47e1-98f3-75b38db59d4c._msdcs.MYDOMAIN) couldn't
         be resolved, the server name (MYSERVER.MYDOMAIN) resolved to the
         IP address ( and was pingable.  Check that the IP address
         is registered correctly with the DNS server.
         ......................... MYSERVER failed test Connectivity
Check for dns name reoslution & also reset secure channel of dc.
Delete msdcs folder & restart dns server & netlogon service.

DCDIAG is a good test. It is saying there is a problem with DNS server. Did you check it for any problems? Do you need help with that?
volfandt87Author Commented:
yes ... How do I check DNS for Problems.... I found this in the DNS event viewer

The DNS server was unable to open the Active Directory.  This DNS server is configured to use directory service information and can not operate without access to the directory.  The DNS server will wait for the directory to start.  If the DNS server is started but the appropriate event has not been logged, then the DNS server is still waiting for the directory to start.

can I delete Aliases in   _msdcs.mydomain.com
delete complete msdcs folder & restart netlogon & dns service it will be recreated.
Abhay PujariCommented:
Yes do that. You can also uinstall DNS Service, restart server and then again reinstall DNS services and then configure your DNS. Set SOA as the IP of your server and also check the name server tab.
Don uninstall dns it will delete all the host record which includes manually created record,except manually created record other records will be recreated on netlogon service restart or machine restart on registering service.

Only delete msdcs folder.
volfandt87Author Commented:
hate to be dumb.... but ... where is the msdcs folder?
volfandt87Author Commented:
Oh...sorry ... delete the msdcs folder from within the DNS management ....right?
Msdcs folder explanation read below

Yes,delete the _msdcs folder form dns management console.

After that restart netlogon,den server service & if the folder msdcs doesn't come run dcdiag /fix & netdiag /fix,it will resolve the problem.
