FwListExceptions.vbs
By The Scripting Guys, Microsoft Corporation
This script lists the open ports and authorized apps for Windows Firewall. To perform this task, the script uses the Windows Firewall COM automation server. It runs only against the local computer.
FwListExceptions.vbs is a bonus script; it does not correspond to any of the scripts that ships with Application Compatibility Testing and Mitigation Guide for Windows XP Service Pack 2 and which are documented in the Appendix. You can download a Windows Installer (.msi) file that installs the Guide and its associated scripts from:
To use the script, copy the code, paste it into Notepad, and then save the script as FwListExceptions.vbs. To run the script, open a command prompt window to the directory of the script and type:
cscript fwlistexceptions.vbs
If the default script host on the computer is Cscript.exe, the initial "cscript" may be omitted.
