My primary domain controllers in our parent domain don't seem to be replicating as they report "failed due to a DNS lookupup failure". NS Lookup seems to be working fine. But when I run NetDiag i get the following error:
DNS test . . . . . . . . . . . . . : Failed
[WARNING] Cannot find a primary authoritative DNS server for the name
The name 'pdc.domain.' may not be registered in DNS.
[FATAL] File \config\netlogon.dns contains invalid DNS entries. [FATAL] No DNS servers have the DNS records for this DC registered.
Looked into the netlogon.dns file, and at first sight there does not seem to be anything amiss. (obviuosly is!) usual active directory entries pronouncing service location etc.
Help! Not come accross this before, and as its stopping users logging on correctly and causing RPC failures this is top priority for us!
