DNS recursive query error

We seem to be having some problems with the DNS server. The error is in the recursive query and wanted to know how to fix it. May be it has something to do with the other server we have our secondary server?
Log Name:      DNS Server
Source:        Microsoft-Windows-DNS-Server-Service
Date:          2/8/2009 12:25:45 PM
Event ID:      7062
Task Category: None
Level:         Warning
Keywords:      Classic
User:          N/A
Computer:      Schwarz18.dmsas.local
The DNS server encountered a packet addressed to itself on IP address The packet is for the DNS name "apps.bzresults.net.". 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.

The error message is quite explicit about what you should check. Have you done any of that? Or are you not sure of how to do that?

In the forward lookup zone  (msdcs.dmsas.local) the Name Server is using the server with the error and also the secondary. Should I remove Schwarz18 from this?

Only if the server doesn't hold a copy of _msdcs. I take it that folder is greyed out in the dmsas.local zone? If so, check the NS Records it shows when you select it.

Figured out the problem,  someone made changed to the NIC DNS servers and therefore giving the error messages. I also found out that we were using the wrong DNS servers for our external DNS. problem Fixed.
