Adding Altiris AClient as Firewall exception through unattended.txt

Hi All,

I was wondering what the commands and code would be to add an exception to the firewall for the altiris aclient. Currently when it first logs into windows to start installing applications a prompt comes up asking whether or not the altiris client should be blocked or unblocked and I have to unblock it before the scripts will begin to run. Does anybody have the details i'd need for this?

Thanks in advance

Byron
