We are having issues with our DC's, 2 of them are not replicating their GPO's and we are receiving the EventID 1030 and 1058 every 5 mins in the event viewer. I have also noticed some of the client computers are not updating their GPO's and have the same errors.
I have goggled around looking at various articles on technet etc... to try and resolve this with no success. and I'm starting to think this is a DNS issue with the name that was chosen for the domain.
DCDIAG produces these errors:
Starting test: Advertising Warning: DsGetDcName returned information for \\elfnet.ELF.local, when we were trying to reach DELL. Server is not responding or is not considered suitable. Warning: DELL is not advertising as a global catalog. Check that server finished GC promotion. Check the event log on server that enough source replicas for the GC are available. ......................... DELL failed test Advertising 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. ......................... DELL failed test frsevent
Any help appreciated.
