Check what port an application is using

There are a couple of applications that may fail to start and complaint because its port is being used by a different application. This is a quick and dirty way of knowing which application is responsible for tying up a port on a Windows box.

Open up a command prompt:

  1. Start | Run | type cmd | Enter
  2. Type netstat -aon | findstr “[port number]“
  3. Take note of the numbers on the last line. This is the PID or Process ID.
  4. Type tasklist | findstr “[PID]“ and this will return the application corresponding to that PID.
  5. Once PID is determined, you can now kill it in Task Manager or kill it typing tskill at the command prompt.


For example:

  1. I type netstat -aon | findstr “8080″ at command prompt (I’m on a proxy by the way)
  2. I see that the PID is 3624
  3. I type tasklist | findstr “3624″ to find what PID 3624 is and it points to msnmsgr.exe which is MSN/Live Messenger.
  4. I can now kill MSN Messenger from Task Manager or type tskill 3624

Auto Logon to Windows XP

Auto Logon to Windows XP

Published: March 18, 2002

Submitted by Doug Knox, Microsoft MVP, Tewksbury, Massachusetts

You can configure Windows XP to automate the logon process if your computer is not part of a domain.

1. Click Start, click Run, and type control userpasswords2.
2. Clear the Users must enter a username and password to use this computer check box.
3. Click Apply.
4. Enter the user name and password you wish to automatically log on with, and then click OK.
5. Click OK again and you’re all done.

This feature allows other users to start your computer and use the account that you establish to automatically log on. Enabling auto logon makes your computer more convenient to use, but can pose a security risk.
