Type Error
Description DNS Server could not open socket for address [IP address of server]. Verify that this is a valid IP address on this machine. If it is NOT valid use the Interfaces dialog under Server Properties in the DNS Manager to remove it from the list of IP interfaces. Then stop and restart the DNS server. (If this was the only IP interface on this machine and the DNS server may not have started as a result of this error. In that case remove the DNS\Parmeters\ListenAddres

According to Microsoft, this problem was corrected in Windows 2000 SP2. See Q260186 for more details.

As per Microsoft: "These errors can occur on computers that have both of the following services installed on the same server: Network Address Translation (NAT) and DNS Server". See Q279678 to fix this problem.

What is the role of a DNS server?
Comments Adrian Grigorof
As per Microsoft: "The occurrence of these event error messages does not necessarily indicate a problem with the DNS service" This event indicates that a number of events were blocked by DNS from being logged in Event Viewer (the number itself is in the "Data" section). After this event, the logging starts again.

In my case, this error appeared after I changed the network and I forgot to change the reverse-lookupzone.

From a newsgroup post: "If you have 2 DC/DNS servers, to avoid this error, make sure you have the following under IP properties:
DC1:
First DNS address points to DC2.
Second DNS address points to itself.
DC2:
First DNS address points to DC1.
Second DNS address points to itself".
From a newsgroup post: "This can be caused if you have a single DC or two DCs and they point to themselves as the first entry in the DNS list in IP properties and the zone is AD Integrated. Reason could be that the DC has many services running on it (SQL, Exchange, etc.) or is a slower machine, and when the Netlogon service tries to register into the zone at boot time, AD is not quite initialized yet and so you get the error. You can either ignore it or change the zone to a Primary, or if you have multiple DCs, change the first entry to the partner and the second to itself".

The error may occure if the "RootDNSServers"-entry was deleted and the DNS-job not restarted.

It is likely that DC either is not configured to use a DNS server that has as valid copy of the DNS zone, or the zone does not have the needed SRV records. Running DCDiag (from the Windows 2000 Resource Kit) may provide some information about the source of the errors. Also, NETDiag can be run for additional information.

MS PSS reports this error may occur in a single-server environment, during server startup, for AD-integrated DNS zones. Apparently, DNS is starting before AD is ready to answer queries, and DNS cannot wait for AD to start since AD needs DNS. PSS reports the error can be ignored, as the DNS zones will load as soon as AD is ready. PSS said that switching to a standard (not AD-integrated) zone would work around the problem.
