Subject: Question about MS DNS server dropping packets from client

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi folks,

While trying to test corner cases of the DNS implementation of Microsoft, I've 
noticed that if I send DNS packets that cause FORMERROR return values, the DNS 
server will silently drop further packets that would trigger a FORMERROR. I can 
still send and get replies to valid packets from the machine that is blocked 
for FORMERROR packets. If I wait a couple of minutes or restart the DNS server 
service, I can get one reply for a FORMERROR packet again, then I'm blocked 
again.

What's going on there, and more importantly, is there something I can do to 
turn this of?

Cheers,
Kai
