I am having issues with my new DC that I am trying to use to replace an old DC to make into a file server only.
I have dcpromoed it and everything seems to be working execpt when I run the netdiag.exe, I get failures in the DNS Test
[FATAL] Could not open file C:\WINDOWS\system32\config\netlogon.dns for reading.
and in the Redir and Browser Test
[FATAL] Cannot send mailslot message to 'Domain' via browser. [ERROR_INVALID_FUNCTION]
and in the Kerberos Test
[FATAL] Cannot lookup package Kerberos.
The error occurred was: (null)
Everything else passed.
Also, I decided to do an ipconfig /displaydns
because well, I thought it was a dns issue.
And I received this
Name does not exist.
However, the servers exist but just not with the _ldap._tcp part.
I moved the FSMO roles (IP, SMTP) bridgehead roles to the new DC and have yet to demote the old DC, fear of no safety net, until I can resolve these issues.
Can anyone help?
Thanks for your time.
