Site: Windows 2003 SP2 DC, DNS, DHCP
Client : Win XP SP2

i was configured dns server in the dc & afterward due to some reason i had
changed the DC name. (Like from skb.com to sk.com).So i promoted the DC & its
working fine with all components.
But i got repeated error in DNS server eventvwr as:
"The DNS server was unable to open zone _msdcs.SKB.COM in the Active
Directory from the application directory partition ForestDnsZones.SKB.COM.
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."
i am not using the skb.com dns server right now.

How can i solve? the Event ID is : 4007
