I have been receiving this error in one of my domain controllers. Unfortunately, the guy is out who can help me and I need a solution to this asap. The IP address is a domain controller and the DNS name is a printer. Does anyone have a clue of what steps i should take? I do not want to screw up my DNS server.

Thanks,

The error:

The DNS server encountered a packet addressed to itself on IP address --.--.--.--. The packet is for the DNS name "------.---.--.--.---.". The packet will be discarded. This condition usually indicates a configuration error.

Check the following areas for possible self-send configuration errors:
1) Forwarders list. (DNS servers should not forward to themselves).
2) Master lists of secondary zones.
3) Notify lists of primary zones.
4) Delegations of subzones. Must not contain NS record for this DNS server unless subzone is also on this server.
5) Root hints.

Example of self-delegation:
-> This DNS server dns1.example.microsoft.com is the primary for the zone example.microsoft.com.
-> The example.microsoft.com zone contains a delegation of bar.example.microsoft.com to dns1.example.microsoft.com,
(bar.example.microsoft.com NS dns1.example.microsoft.com)
-> BUT the bar.example.microsoft.com zone is NOT on this server.

Note, you should make this delegation check (with nslookup or DNS manager) both on this DNS server and on the server(s) you delegated the subzone to. It is possible that the delegation was done correctly, but that the primary DNS for the subzone, has any incorrect NS record pointing back at this server. If this incorrect NS record is cached at this server, then the self-send could result. If found, the subzone DNS server admin should remove the offending NS record.

You can use the DNS server debug logging facility to track down the cause of this problem.

Either somebody made a static record for the printer and assigned it the IP of the DC mistakenly (which is a MAJOR problem), or the IP of the DC has maybe changed.
Check the DNS zone and confirm the host/A record for the printer reflects the IP of the DC. If it does, go to the printer, ensure it is in fact using the same IP as the DC, and change it. As long as you map by printer name, and not by printer IP, you'll be good to go.

Thanks for your help. For some reason there was another location that was in the subzone.
