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
