Hi ISAlist, 
 
I have a requirement. I am using ISA 2000 Standard Edition 
 
I want to Block all Websites Except the specified email websites Hotmail, Gmail 
and Yahoo Mail. 
 
I don't want anyone to use the search engine of Yahoo, Gmail and MSN Search 
Engines but email sites must be used 
 
I tried to block using site and contents Rules. 
 
First I create a destination set and add the above site by adding the website 
address and then I also add the IP address of the above mention website 
address. (I find the IP address by nslookup for the websites)
 
Second I create an Allow Rule in Site and contents to Allow the traffic for the 
above mention destination Rule 
 
Second I create another Rule in Site and Contents and Deny "All destination 
except selected Set" and in the selected set I mention the above created 
destination set.
 
When I apply all of the above only hotmail website worked but Yahoo Mail and 
Gmail didn't worked it says ISA Server denies the specified URL
 
I will be very much thankful if some one may guide how to BLOCK ALL Website 
Except the Specified Website Yahoo Mail, Gmail and Hotmail.
 
 
Waiting for a positive response and detailed reply with steps of how to do it.
 
Regards, 
Moazzam Iqbal
