Hi guys,

Got an issue with software that needs a certain UDP port open. Now UDP is conenctionless so I cant test it with telnet. I have used port Query from MS (http://support.microsoft.com/?id=832919 and I have ran it against that UDP port.

I basically get a response of listening or filtered. Listening is what I am looking for but filtered means there is no response so that answer is not definitive.

Does anyone know a tool that I can run on our a windows machine (XP / VISTA) that will give me a clear indiciation that X computer is in fact listening on UDP port XXXX.

It also needs TCP but I can use telnet to test the connectivity for that.

I am open to suggestions.

Thanks
