Want to log into 1 internal booking website without Authenticating, without the ISA log on screen coming up.
Looking in the Listener Tab & using HTML Form based Authentication & not using SSL.
Any ideas we'be tried many different combinations to no avail.

Is your proxy server enabled in ISA? If yes, how will you be able to be unseen browsing the net without going into the gatekeeper, that is ISA?

You can  allow a rule to allow x many users to go to the site, enabled single sign on on the internet explorer!

So, the site is internal to your organisation? ISA should have a rule to automatically direct requests to internal sites without proxying. Alternatively, you should be able to add these sites to exception list on IE.

You are not supposed to be going through the ISA/TMG to get to web sites that are already on the same side of the ISA/TMG as you are on.

If it is getting in the way, then you have thing miconfigured.  All of these below are "bad",...don't do them:

1. Fail to include the AD Domain Name in the Domains Tab in the Properties of the Internal Network Definition

2. Fail to have the full IP Range of the Internal LAN listed in the Addresses Tab in the Properties of the Internal Network Definition

3. Access any web site by using the IP#.  Do not do that,...always use a name.  There is a flaw in the logic of IE in how it determines what to send tot he proxy and what not to send to the proxy.  Other browsers may have the same flaw. The Netbios Name of the target server works the most dependable, but using the FQDN should work fine too.  Here is futher information on that:

Intranet site is identified as an Internet site when you use an FQDN or an IP address
