How to clear saved Windows networking passwords

I had a problem connecting to shared VPN network folder because I changed my password but Windows kept using the old one stored in its cache. There was no obvious way to tell Windows to prompt for a new password. After some googling, I found the following command line that displays a dialog showing all the stored credentials and that gives the possibility to delete them : rundll32.exe keymgr.dll, KRShowKeyMgr It saved my life!!!
