Right click on  Command prompt  or  PowerShell   in menu click  Run as Administrator   on Windows XP you can just run it as usual    As Rick Vanover mentions in See what process is using a TCP port in Windows Server 2008      The following command will show what network traffic is in use at the   port level   Netstat -a -n -o    or  Netstat -a -n -o  gt  USERPROFILE  ports txt    to open the port and process list in a text editor  where you can search for information you want   Then       with the PIDs listed in the netstat output  you can follow up with the   Windows Task Manager  taskmgr exe  or run a script with a specific PID   that is using a port from the previous step  You can then use the    tasklist  command with the specific PID that corresponds to a port in   question    Example   tasklist  svc  FI  PID eq 1348

If you want to be really fancy  download TCPView from Sysinternals      TCPView is a Windows program that will   show you detailed listings of all TCP   and UDP endpoints on your system    including the local and remote   addresses and state of TCP   connections  On Windows Server 2008    Vista  and XP  TCPView also reports   the name of the process that owns the   endpoint  TCPView provides a more   informative and conveniently presented   subset of the Netstat program that   ships with Windows

Type in the command   netstat -aon   findstr  80   It will show you all processes that use port 80  Notice the pid  process id  in the right column   If you would like to free the port  go to Task Manager  sort by pid and close those processes   -a displays all connections and listening ports   -o displays the owning process ID associated with each connection   -n displays addresses and port numbers in numerical form
