You should check out netcat. I've never used the Windows version, but the *nix version is great for scripting because you can check if a port is 'open' (example command: nc -z -n 172.16.0.1 677), and it will return true or false accordingly. It would surprise me if the Windows version did not have the same capability.

I want to be able to do individual ports and not port scans. Say for instance I wish to verify that port 677 is closed to traffic on ip address Ex. 172.16.0.1, I'm looking for a utility that would do something like: Check 172.16.0.1 port 677 and tell me whether that port was reachable. So if I have two networks and I use this command from one I can determine whether a port is reachable on another. To determine whether a security measure is failing or not. There may be a simple way to do this...
