Block MSN on Windows NT 4.0 server and Windows 98 clients
Hi,
I work in a school.
We have a Windows NT 4.0 server, Microsoft Proxy 2.0, IIS 4.0
And we have several clients on windows 98 SE
What I want to do is to block students installing and using MSN for messages and chat... while they are supposed to be working!!!
I have been very surprised to learn that MSN works on the win98 computers since I have not installed the Winsock Proxy Client...
I would like to block MSN with the software I already have... if possible...
Is there an group of IP adresses I can block in the server's proxy???
Thank You

If, on your router or firewall, you block ports 135 thru 139, that should do the trick for Messenger. Also just going into services on the workstations and setting the messenger service to "disabled"

Hmmm...
I have found that if I deny the address 65.54.226.254 (Loginnet.passport.com) In the "Permission" shared service of Microsoft Proxy 2.0..... Students are unable to connect to MSN... great!!!
But teachers nor can access to Hotmail.Com via internet Explorer...
Hmm... a lot of teachers here use hotmail...
Is there a way to just block MSN???

If you just want to block MSN IM, disable the messenger service.

JConchie,
There are no firewall or router here...
There is one firewall at the schoolboard, for the 55 school, but I would have liked to block MSN by myself, at the school... if possible...
If eventually the schoolboard blocked the ports 135 thru 139... would it affect something else than MSN???
> If you just want to block MSN IM, disable the messenger service.
Where??? On each clients computers??? (Win98)
If so, the students will uninstall MSN, and Reinstall... and I suppose it will work again...
Thank You

Yes, on each client computer..........and if you don't give them local admin rights, they cannot change the service back to automatic........and they also will not be able to uninstall or install apps

JConchie, I think you're talking about Win XP clients...
I have only Win98 clients... and there is no local admin rights on that Os... I think???
Except with poledit... But even with poledit installed and all the restrictions applied... they still can install software...
