I am testing an application which communicates to a server via a UDP port, and I need to block this port to make sure the application can handle it.
The Problems:
1. It has to be done in an automated test (which is controlled by VBScripts).
2. It has to be done in Windows XP, without using a firewall.

I have tried this:

 Set objFirewall = CreateObject('HNetCfg.FwMgr') Set objPolicy = objFirewall.LocalPolicy.CurrentProfile Set colPorts = objPolicy.GloballyOpenPorts  Set objPort = colPorts.Item(9999,6) objPort.Enabled = FALSE

but it did not work.
