This happened to a server that has been working fine for a couple of years. Suddenly the network become sluggish (day 1) and then on day 2, we werent able to find shared folders. After checking, I found that the forward & reverse lookup zones in my DNS server has disappeared. It is a Windows 2003 server, with DHCP, DNS and AD installed on the same box.
When re-creating the forward & reverse zones, I'm getting this error:
"The zone cannot be replicated to all DNS servers in the (null) Active Directory domain because the required application does not exist. Only Enterprise administrators have the appropriate permissions to create an application directory partition. To store this zone in a domain container until the partition is created, close this message, and then replicate to all domain controllers in the active directory domain option."
Which is documented on Microsoft website: http://support.microsoft.com/kb/938459
but it doesnt seem to be connected to my problem as I wasnt trying to create a new DNS/AD. ANyhow, I've tried it and was not successful.
Thank You for your help. I've been getting so many computer problems nowadays.... I may need a real network admin to do this...
