Question : DNS / Replication problems

Here are the results of Netdiag and DCdiag. I need help resolving the problems below. The reason why I'm running diagnostics is because it take a very long time for new GPOs to kick in.

This is a DCdiag:
Starting test: frsevent
There are warning or error events within the last 24 hours after the SYSVOL has been shared.  Failing SYSVOL replication problems may cause Group Policy problems......................... MARTINI failed test frsevent.

This is a NETdiag:
DNS test . . . . . . . . . . . . . : Failed
[FATAL] Could not open file C:\WINDOWS\system32\config\netlogon.dns for reading.
[FATAL] No DNS servers have the DNS records for this DC registered.

Kerberos test. . . . . . . . . . . : Failed
[FATAL] Cannot lookup package Kerberos.

Answer : DNS / Replication problems

Hmm I think you simply have the wrong version of NetDiag there. Is DCDiag clean?
