This script opens specified ports in Windows Firewall. To perform this task, it uses the Windows Firewall COM automation server. It runs only against the local computer.

OpenPorts-com.vbs corresponds to OpenPort.vbs, one 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 OpenPorts-com.vbs. To run the script, open a command prompt window to the directory of the script and type:

cscript openports-com.vbs

If the default script host on the computer is Cscript.exe, the initial "cscript" may be omitted.
