The other day i was looking at the logs from our Firewall-1 and saw a 
portscan starting at port 1 all the way up to 65535. Of course i start 
looking at it further & discover it's come from the *inside* of the wall. 
Looks like one of the users has been playing around, so pausing only to 
pick up the office baseball bat on the way out, i go to have a quiet word, 
but when i talked to him he said it's part of the beta Netmeeting 2 from 
our old chums Microsoft. I haven't looked at it myself but i'd take our 
guy's word for it. He says it's a few lines of VBasic which looks for a 
port to use. Seems to me this is, how shall i put it? Irresponsible? 
Designed to piss off Firewall administrators?

Anyone else come across this? Anyone from M$ care to comment?
