A couple people asked to be notified of any
resolution of this problem.

The folks that were having this problem tell me it
went away after they took out the 3127-3198 TCP
port blocks into their network. ;)

When they originally called me, they reported a huge
volume of calls with the symptoms I described. I
checked with our folks who told me they had run across
a few with the same symptoms. That led me to the post to
unisog so I could see how widespread the problem was
while I was trying to find an actual computer. I still
haven't found one and I don't think I will. :)

We've been blocking *unestablished* sessions to 3127-3198
for the whole campus since the day MyDoom came out without
any reported problems and all unestablished sessions into
the student networks have been blocked since the fall.
