I'd like to understand how a specific windows process (from a third-party vendor) behaves when it's selectively blocked from communicating on a network (by say, an overzealous software firewall). Is there a free (and ideally light-weight) tool I can use to do this? I don't want to block ALL network connectivity on the user workstation - just connection attempts from a specific process.

Why the -1? This pertains to enterprise support / analysis for a user workstation. –  Mike B Feb 5 at 16:04

This can be done using Windows Firewall. You can set some restrictions based on application instead than on in/out ports.

Here you can find a nice tutorial: http://www.technipages.com/blockunblock-programs-in-windows-firewall
