I have a parent child domain setup. We tried to do an Exchange schema update last night and were seeing some possible issues with AD. After some reboots of all the data center DCs the event logs for both domains appear clear and the logs state all issues have been cleared but I noticed DNS Event ID 4010 on both our parent DC's pointing to the record for the child domain. The DNS server was unable to create a resource record for 997a6da4-64bb-4a34-a65d-6766a2d1834a._msdcs.na.int-bn.com. in zone int-bn.com. The Active Directory definition of this resource record is corrupt or contains an invalid DNS name. The event data contains the error. I found a previous post stating to: Stop the netlogon service. Go to Windows\system32\config and rename the netlogon.dns and netlogon.dnb files to netlogon.dns_old and netlogon.dnb-old . From a command prompt type "ipconfig /flushdns" then run "ipconfig /registerdns" and then start netlogon again and check the event log if the error reoccurs. But their issue, it appears was for the primary domain and I'm curious if I should try the same steps for the my issue. Any help would be appreciated. I can't apply the Exchange patch until this is resolved.
