"File and Printer sharing" firewall exception scope in Vista ?

I'm have a problem getting the printers to show up in Print Management MMC.

I need to change File and Printer Sharing's exception (those 4 ports) scope

from "local subnet" to "Any computer". It was easy in XP - I

could click on the "Edit" button and choose "change scope" button and do the

job. But not in Vista. There is no "Edit" button. "File and printer sharing"

firewall exception doesn't list those 4 ports, and of course there is no way

to change scope.

How to I change "File and Printer sharing" firewall exception scope in

windows Vista to make Print Management work?

Thank you,

Joe
