GP errors

I seem to be having issue with some of our servers within our domiain generating these errors on a regular basis:

Windows cannot access the file gpt.ini for GPO CN={31B2F340-016D-11D2-945F-00C04FB984F9},CN=Policies,CN=System,DC=ldc,DC=*domainname*,DC=co,DC=uk. The file must be present at the location <\\*DOMAINNAME*\sysvol\*DOMAINNAME*\Policies\{31B2F340-016D-11D2-945F-00C04FB984F9}\gpt.ini>. (The format of the specified network name is invalid. ). Group Policy processing aborted.

and then we would recieve the error:

Windows cannot query for the list of Group Policy objects. Check the event log for possible messages previously logged by the policy engine that describes the reason for this.

We have recently added 2 new windows server 2008 R2 Domain controllers to the domain using forest functional level of Windows server 2003.

Does anyone know a way I can stop these errors from being generated.

Thanks

Is this the DC in which FRS service is running and you are getting the errors?

Upload "repadmin /showrepl dc* /verbose /all /intersite >c:\replication.txt"

And also

dcdiag /v /c /d /e /s:dcname >c:\dcdiag.txt

Post a plain dcdiag without switches. Seems like the Windows 2008 Server aren't fully replicated which we can fix pretty easy but I need to make sure that is the problem

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

Check your DNS settings you should be only pointing to internal DNS servers only in the TCP\IP properties
jmanishbabuCommented:
Check the Primary DNS servers configured .  Point it to local host and to the Secondary DNS server to the  nearest available DC .

We seem to be getting entries in a few member servers in the domain with the following :-

Windows cannot access the file gpt.ini for GPO CN={31B2F340-016D-11D2-945F-00C04FB984F9},
CN=Policies,CN=System,DC=ldc,DC=intamac,DC=co,DC=uk. The file must be present at the

These errors are only happening on a few member servers in the domain
Darius GhassemCommented:
Have you run dfsutil /purgemupcache
ccfcfcAuthor Commented:
IT seems possibly that a "non microsoft" service is the issue so, running "start msconfig" and disabling these services and waitng to see if GP repliactions occurs.
Problem then is, working out what services is creating the problem.

no other solution has been found.
ccfcfcAuthor Commented:
All it seems after long discussions with Microsoft and our Anti-Virus provider, Kaspersky, we seem to have found the solution.

It seems that the the Primary DC was the only server which was having the issue with the group policy as other servers which was using the secondary DC on our network were all downloading the group policy OK. Also the affected clients, I moved over to the secondary server, and seems to be working OK.

Therefore having a look at the config, our primary DC has Symatec Endpoint Installed and running which i believe is causing the issue as the secodnary DC has Kaspersky Endpoint installed and works fine. Removed AV and seems to be working OK again.
