I look after a simple Windows 2003 server setup with 5 clients. However I am getting lots of event 7062 errors:
"The DNS server encountered a packet addressed to itself on IP address 192.168.0.20. The packet is for the DNS name "_ldap._tcp.a2700020-cc38-
.". 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
-> 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.

I have looked on EE and around the internet and I find a Microsoft Support document that lists how to fix it. The problem with it is that it refers to Windows 2000 and NT 4.0 so some of the fixes it suggests aren't there.
Any help greatly appreciated.
