DNS Warning in event viewer
Posted on 2006-06-22
I am continuously getting this warning in the event viewer. i have an active directory integrated DNS server (ip 22.214.171.124)
The DNS server encountered a packet addressed to itself -- IP address 126.96.36.199.
The DNS server should never be sending a packet to itself. This situation 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.
Example of self-delegation:
-> This DNS server dns1.foo.com is the primary for the zone foo.com.
-> The foo.com zone contains a delegation of bar.foo.com to dns1.foo.com,
(bar.foo.com NS dns1.foo.com)
-> BUT the bar.foo.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
I have not enabled Forwarders list
other things pls let me know where to look at.
Thanks in advance
