Make Windows Forget Your Network Passwords
Here's a reminder for me of how to get Windows XP to forget your stored network passwords. You might want to do this for security reasons or if conflicting network passwords are causing logon problems. If I don't write this here, I'll never remember it...
Go to Start -> Run, then enter this:
rundll32.exe keymgr.dll, KRShowKeyMgr
Windows Key Manager
I'm sure you can work out the rest. Hope that was some use to you.
