For now we're running Windows Firewall on our desktops (XP SP3) and managing it with a GPO as all these systems are members of our single Active Directory domain. I'm wondering if there is any way to set a rule that says "open this TCP port but only for this particular system". As in we want to open a port to one PC that'll be doing some web app serving tests before we move the web app to a server, and multiple PCs will be connecting to that port. But I only want that port open on the single host PC. Alternately, is there a way to over-ride the domain deployed rules by setting a local exception on that host PC?

You can do this be playing around with the GPO scope. Either move the computer account to an OU where the firewall GPO does not apply, or apply filtering to the GPO permissions to deny "apply policy" for this particular computer.

Hmmm...I don't want to move this system out of it's current OU, and filtering sounds complex as I only want to filter for this one rule and keep all the other current (and future) rules. But it's an idea...thanks.
