RE: Restricting use of MSN Messenger
Instant messenger programs have a habit of using things like port 80, that you probably don't want to block. Most firewall vendors will have technotes for blocking the commonest IM programs though. Try yours.

RE: Restricting use of MSN Messenger
If you are using MSN through proxy then see logs file and block the IP's/web sites used by MSN Messenger. I have blocked MSN once by doing this. -Original Message- From: Mike Scott [mailto:[EMAIL PROTECTED]] Sent: Friday, February 01, 2002 3:30 PM To: Exchange Discussions Subject:RE: Restricting use of MSN Messenger Instant messenger programs have a habit of using things like port 80, that you probably don't want to block.

Note that AOL IM, newer versions of ICQ, and Yahoo IM all use arbitrary ports on dedicated servers, so you have to block IP addresses instead. Fortunately, you can lookup the IP addresses via DNS (assuming your firewall supports such things). -- Ben Scott [EMAIL PROTECTED] | The opinions expressed in this message are those of the author and do not | | necessarily represent the views or policy of any other person, entity or | | organization.

RE: Restricting use of MSN Messenger
Maybe you should just talk with him and save yourself some work. If he shouldn't be using it, then let him know. If that doesn't work, then why the hell is he still employed with you.. If you restrict access and he just comes into work one day to find it won't work any more, then he will be confused/upset. I think it would be better to just tell him how it is..! Either way you really should have a firewall in place. Internet connections and corporate LANs make for a bad mix sometimes. Do it with Linux or *BSD, that way it is FREE and Secure.. hehe Good luck, just my thoughts ~John -Original Message- From: Darren Ash [mailto:[EMAIL PROTECTED]] Sent: Wednesday, January 30, 2002 12:38 PM To: Exchange Discussions Subject: RE: Restriciting use of MSN Messenger Unfortunatley YES.
