I have a Winows 2000 Server (SP4) running IIS 5.0. I have installed MS Proxy Server 2.0 which is running Web, WinSOCK and SOCKS Proxy services. NTLM is enabled on the server.
Clients in the network (Win9x, Win NT/2000) use the Web and WinSOCK proxy services.
Please let me know the solution for the following two requirements:
1. I want to block MSN Messenger completely.
2. I want to block file transfer through MSN Messenger.
The configurations are desired to be done on the Proxy server only.
