Blocking Google's Assc like orkut,youtube, Gmail , Except Google.com

We have isa2004 installed . i blocked orkut and youube, but found that users
were able to accesses these sites. But when i disable google.com i found that
these sites got blocked as well. Now how do i block these sites and still
give users access to Google.com

Now if orkut is blocked there as sites like powerchat which gives a back
door access to orkut.com, how can i prevent this

All help is appreciated

It is pretty much impossible,...as you are finding out.
The Internet is way too "porous" and "vague",...there is almost no such
thing as a "single" sef-contained site anymore.

Blocking Domains and URLs only work for Web Proxy Clients,...not for
Firewall or SecureNAT Clients.

Hi

I have recently tried to banned sites like orkut,youtube and gmail using 
ISA2004. However the sites can still be accessed. But if i block google , the 
other sites are also blocked. 

How do i block the above sites, without blocking googles search engine. Also 
if *.orkut.com  is blocked there are sites like powerchat which will allow 
them to access. How is it possible to completely ban the connection to orkut 
server

Also if i have to ban sites which fall on same categories. Ex: Porn sites . 
It is difficult for administrator to go around and check for all the sites 
and block all url. Is there a way it block the sites if the requested sites 
contents or url contain reference to porn or sex or any stuff like that.

All replies is much appreciated
