Hi Mario, Check your Web Proxy and firewall logs to determine what sites/addresses the MSN clients connect to Create a site and content rule to block access to those sites Force all clients to be Web Proxy clients. Disable the HTTP Redirector to show them you mean business :-) Configured the clients as Firewall clients Configure the mspclnt.ini file to block the Messenger exe file HTH, Tom Thomas W Shinder www.isaserver.org/shinder <http://www.isaserver.org/shinder> ISA Server and Beyond: http://tinyurl.com/1jq1 <http://tinyurl.com/1jq1> Configuring ISA Server: http://tinyurl.com/1llp <http://tinyurl.com/1llp> -----Original Message----- From: Mario Videira [mailto:videira@xxxxxx] Sent: Friday, February 14, 2003 9:01 AM To: [ISAserver.org Discussion List] Subject: [isalist] MSN Messanger http://www.ISAserver.org Hi all, I have Isa Server in my LAN. I have tried to block MSN Messenger using Isa Server in all host of my LAN. So, have down the following: From Isa Server, i have used a Protocol Rule, then right click and choosed new Protocol Rule with the this parameters: name: msn action: deny protocols: selected protocols and choose msn messanger But, the results was that the clients went on using MSN Messanger. Any Idea, how can i get good results, i.e., blocking MSN Messanger using Isa Server?
