Hi all, Sorry my english!!! I am new with ISA SERVER, so i have the followings questions: I have installed on my machine, Windows 2000 Server, ISA SERVER and MSN Messanger chat. So, i want that ISA SERVER blocks MSN Messanger chat. How can i configure ISA SERVER to get that? I want to store on cache created by ISA SERVER, for example, this URL, http://www.hotmail.com , to allow that clients go to the cache to search the URL, instead of go to the Internet. How can i configure ISA SERVER to get that? How can i configure ISA SERVER to block some URLs?
