My Win2k DC DNS failed, there are two errors being logged:

Event ID: 4015
Source: DNS
Description: 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.

Event ID: 4004
Source: DNS
Description: The DNS server was unable to complete directory service
enumeration of zone 1.168.192.in-addr.arpa. This DNS server is configured to
use information obtained from Active Directory for this zone and is unable
to load the zone without it. Check that the Active Directory is functioning
properly and repeat enumeration of the zone. The event data contains the
error.

I check the AD on this server, it works properly. The DNS just said "Zone
not loaded by DNS Server", DNS MMC can't be opened. I tried to run dcpromo
to remove the AD from this DC, but the dcpromo can't be completed. It
prompted the DNS can't be contacted error. I'll be very appreciated for any
advice can be given for me to make the server DNS work properly again.
Thanks in advance first. Thank you!! :)

Normally these event appear only at start up if you only have one DC.
Obviously, from your post you are getting these events continually after the
computer has started.

Are all AD zones affected?

Are you using ICS on this DC?

You only have one DC?
Do these errors continue after the server has started?
