Have had a problem at two occasions sofar with the dnsserver handing
out completely wrong ipaddress.

We have two dnsservers, primary and secondary.
Our outgoing mailserver normally gets the correct response to one of
our other server when delivering mail, in this case mercury-1.hkr.se
with ipnumber, but at two occasions the dnsserver has
responded 244.210..... something, and the mail doesn't get delivered.
This has always shown up in the weekend.
The primary dnsserver was the one answering wrong, the secondary
dnsserver answered correctly.
When I reloaded named on the primary server it started to answer
correctly again.
Is there anyway to steal, snatch or manipulte the ipaddress on the
Both server are nw5.1sp6 and named is version 5.12e
