Is there any port scan tool that can do what netstat does and also has a filter feature, so that unnecessary connections can be hidden?

Another alternative is CurrPorts : Monitoring TCP/IP network connections on Windows

You could also just pipe the output of netstat into find e.g.

netstat -n | find "10.0."
netstat | find /I "pcname"
netstat | find "ESTABLSIHED"

I do this a lot, people always turn their head sideways when I do it but once they see the result their good! – user33788 May 21 '10 at 2:18
I normally go one step further and install a grep for windows but find works well enough for this. – Sim May 22 '10 at 3:47
Yep, +1. Piping into find and not having to install 3rd party tools works just fine for me. – MDMarra Jan 31 '11 at 16:05

Sysinternal's TCPView may do what you are looking for, if a GUI tool is fine for what you are trying to do.

How do you filter out connections in TCPView? – MDMarra May 20 '10 at 23:40
I've just fired up my old copy and it seems that you can't. I must be thinking of some other tool - I'll try remember what that is... – David Spillett May 21 '10 at 8:17
