Hello All,
Few days ago, I added two ns entries into my DNS
cache file, Since then the DNS server dies after every
two hour or so, the event log registers the listed
below event for the DNS server, the whole log file is
full of such messages. Can anyone please help me how
to solve this problem.
I have changes the cache file with a fresh cache
file , restarted the DNS server, but still the old
cache records come up , and the original cache records
are lost. I also altered the DNS zone file to remove
the problem , but nothing is working, I have attached
the DNS zone file , and the event viewer message is
listed below, please help me with this one.
"DNS Server encountered a packet addressed to itself
-- IP address xxx.xxx.xxx.xxx. 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 DNS server Example: -> This DNS
server dns1.foo.com is the primary for the zone
foo.com. -> You have delegated the zone
bar.foo.com to bardns.bar.foo.com. and are NOT
running the bar.foo.com zone on this DNS
(dns1.foo.com). -> bar.foo.com MUST NOT have an NS
record that points at dns1.foo.com. Note, you
should make this 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. "

Imran Aziz
