I was looking for a Port Scanner today which will run from Windows Vista.
I tried the good old F-port, but it did not work under Vista Ultimate 64Bit. It game me a message about it having to run with Administrator privileges which I was doing.
F-Port can be downloaded from
The tool I found online which worked very well, is free, it looked nice and simple to use to scan either one machine or a range of machines was called Advanced port Scanner 1.3 from www.radmin.com
Advanced Port Scanner is a small, fast, robust and easy-to-use port scanner for Win32 platform. It uses a multithread technique, so on fast machines you can scan ports very fast. Also, it contains descriptions for common ports, and can perform scans on predefined port ranges.
General Information

- File Size: 426 KB

Even though Vista is not mentioned as a supported OS it did work for me.

Even though this looks nice it does not tell you which application has which port open which is a pain.
