Hi Steve. You replied to my earlier post about restricting web sites using
destination sets and s/c rules in ISA.

I had a default set of SBS2003 rules. I am able to ALLOW  a user access to
all websites except for hotmail.com (for example). BUT I am unable to DENY
the user access to all websites except for hotmail.com

When the 2nd scenario is in place all websites seemed to be barred, as
though the specific allow (for hotmail.com) is being ignored.

As I undoubtedly explained, Deny always beats Allow.

So, any Rule that Denies All effectively kills all access (this is handy
to know if you've got a trojan/spyware/whatever spewing crud to the net).

You need two Rules:

* one to Allow access to specific sites (or a blanket Allow All)
* one to Deny access to "All except Selected Destinations" using the
allowed sites set

Thanks for the reply again steve.
I have the ALLOW ALL rule as you explained. I also have a rule which Denies
access to "All except Selected Destinations" for the user in question. When
trying to access ANY destination from the users client PC I am prompted for
username and password to connect to ISA. I have installed ISA SP2 if that
has any bearing.

Confused !
and thanks again,
Gary

Steve, sorted it. Looks like a corrupt "test user". Used a different live
user, all worked OK. Thanks again
