DNS forwarding to 'unknown' DNS server/

We are netware 5.1.
I have 2 DNS server, both are configured with a forward address.
On our firewall, i have seen that my dns servers are making request
(sometimes) to others serves.
Some address are in the rootserverinfo (m.roots-erver, ...) and other
names like blackhole-1.iana.org.
I don't understand why it looks for m.roots-server ... because my
forwardings are configured and why it looks for black....

Are you sure those requests are from your DNS server and not from
workstations on your network? You might download DBGLOG.EXE -- with it
you can record the NAMED.NLM activity to log file so you can see
exactly what the DNS server is doing.

OK, let's try this then...

Start the logging process.
Duplicate the issue.
Stop the logging process.
Copy and paste the log file contents into a reply here.

First, I need to see the whole file, which is why I asked you to start
logging, dupicate the problem, then stop logging. Given that, yes, if
you want to send the whole file, send it to 'nscsysop at comcast dot
net'. Please reply here to let me know you've sent it. Thanks,

Lessee....

nscsysop at comcast dot net

..."at" = "@" (seems you got that part), "dot" = ".", remove all the
spaces, and that should do it. Otherwise, maybe comcast doesn't like
your ISP?
