Hi Ace,

I think that was my post at EventID, matches what I submitted. We've gotten
a few more 7050 errors that was not my co-worker doing a port probe -- the
new 7050 events happened at about 2:30 am and 3:30 am est 6 days apart on
all four DNS servers (two are AD empty root, two are AD child) at HQ.
Interestingly, too, even though all 4 servers in same switch, our 2 AD Root
servers also reported 7050 on two other days at 11 am and 2 pm respectively,
whereas the child servers did not. The 11 am and 2pm I can possibly see as
port probes (most of HQ is software engineers), but 2:30 am and 3:30 am?

None of the DNS servers are public, all internal and AD structure hidden
from Internet. DNS looks fine, no one is having problems, no other errors
(System, Application, Directory Service, NTFS, Security logs).

I still think first occurance was port probe, too much coincidence that 7050
occurred on every DNS server exactly when port probe done. But I'm back to
investigating cause of newest 7050s, if same cause or not. Did a Google
search, saw this thread and thought I'd post the additional info. Still
investigating.

No need to reply.

Regards,
Joan
