The DNS 7062 error is a really quite annoying and frustrating error which can be caused for a variety reasons; The error message in the event log is as follows;
“The DNS server encountered a packet addressed to itself on IP address xxx.xxx.xxx.xxx“
To troubleshoot this problem take the following actions.
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.
