Need Authentication pass through for iMac's on ISA Server 2004

[gavin412]

I have a Windows 2003 ISA 2004 server. We also have a number of Mac's that don't authenticate against the proxy server at login, and therefore require authentication through the browser when they go to get on the internet.

The problem we have ran into is that we have installed Adobe CS3 software which requires that it goes out and registers. Unfortunately, since this all occurs behind the scenes, there is no way to authentic and the software fails to access the internet.

The only solution we can think of is to give the iMac's pass through abilities of the ISA server. Not being an ISA admin or expert can someone tell me what the best way to go about giving the iMac's pass through capabilities on the ISA server so they don't have to authenticate to get out to the internet? Possibly using their IP address?

Thanks in advance

I believe you just set the imacs/macs to be SNAT clients. Then they essentially work on the Internet without the need to authenticate.
