Question : Reverse Lookup Zone Issues

Hi Experts, We have a domain where the client logins are quite slow. Ive been looking around and have found that the reverse lookup zone has a different subnet to the rest of the network. Local IP addresses are 10.0.0.x and the reverse zone has 10.0.2.x

Ive checked the DNS event log and get the following 4007 errors;
1.
The DNS server was unable to open zone _msdcs.hallamplastics.co.uk in the Active Directory from the application directory partition ForestDnsZones.hallamplastics.co.uk. This DNS server is configured to obtain and use information from the directory for this zone and is unable to load the zone without it. Check that the Active Directory is functioning properly and reload the zone. The event data is the error code.

Would the issues with the reverse lookup zone give slow logins and how do I fix the errors?

Thanks Simon

Answer : Reverse Lookup Zone Issues

The two errors you're getting... Do they coincide with a reboot? Or occur on a regular basis?

Is DCDiag clear of errors?

You can delete and re-create the Reverse Lookup zone if you wish, no harm there. That should have no impact at all on domain logon though.
