I have a secondary dns server,which is internal to LAN and on windows 2000
that is generating a lot of queiries for all the 13 root dns servers.The
traffic is blocked by the firewall.But the strange thing that I have
noticed is that the source and destination port being the same i.e 53.Also
whats the problem with that? in bind, up to version 4, source and destination
port of dns packets was always 53, it changed with version 8. i don't know
how win2k dns servers behave, but it may be the same way.
the forwarder is correctly set on the DNS server and hence theoritically
the querries need to be forwarded to the next DNS server.
Any body got an idea as to what is this.
