Hi All,

We have a LINUX internet gateway which has been very stable an
reliable for the past year or so. We have been adding a cluster of
NT4.0 server for our own inernal nework without any problems.

Our systems guy loaded NT4.0 service pack three to the primary domain
controller and this has caused our NAMED process to refuse
connections.....

There have been no changes on the LINUX side for many months, the
error messages we are getting are like:

Aug  5 23:35:11 cca named[52]: recvfrom: Connection refused
Aug  5 23:35:12 cca named[52]: recvfrom: Connection refused


repeated many times. Strangely, it is incoming queries that are
effected, at least initially, then all connections are refused.
Even rebooting the server doesn't fix it, although restarting NAMED
did temporarily resolve the problem overnight.

I did notice an article on another LINUX group that spoke about NT 4.0
clients sending silly requests to the DNS server, does anyone know if
this is fixed in a later version of LINUX. We are running 1.2.8.

Regards,
