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???
