Hi porkchopexpress,
Thanks for your help!
Here is the error message...
The DNS server has encountered a critical error from the Active Directory. Check that the Active Directory is functioning properly. The event data contains the error.
EventID 4015 & 4004
In the newsgroup online, they said...
In one case, this happened on a Windows 2003 SP1 computer, which was a domain controller with Active Directory integrated zones, where the DNS Server address had defaulted to 127.0.0.1. Five of these Event IDs were preceded by EventID 4004 from source DNS.
Changing the DNS server address did not solve the problem. DNS was uninstalled and reinstalled (go to Control Panel -> Add/Remove Programs -> Add/Remove Windows Components -> Networking Services) without an intervening restart of the computer. The DNS Server was then checked and minor configuration changes made. The computer was restarted and EventID 4004 or 4015 did not reappear.
What do you think? Can I remove DNS server & re-install it in the DC?
Thanks again!
