If you want to find out what program is running the port check out (atstakes)-fport http://www.atstake.com
It will link every program that binds a port to the port
A lil snippet from my box
"660 svchost -> 135 UDP C:\WINDOWS\system32\svchost.exe
4 System -> 445 UDP
704 svchost -> 500 UDP C:\WINDOWS\System32\svchost.exe"
