Firstly, I was trying to reply to your mail to me about blocking messenger service BUT it seems that your mail server is DOWN, anyway if you are filtering www access by using ISA server, then you will require the following on your pix:
Using ACL (Named in this case) you would do the following:
>access-list inside permit tcp host XXXX any eq www
>access-list inside deny tcp any any eq www
>access-list inside permit ip any any
..now configure the ACL to the inside interface with a access-group statement i.e.
>access-group inside in interface inside
(NOTE. ON THE FIRST ACL ABOVE XXXX IS YOUR ISA IP ADDRESS)
Also, after you have configured the ACL's make sure you do a wr m (write to memory)
