Windows File Sharing Technical Tip
If you’re trying to get logged into another machine, and you put in some bad credentials, but Windows doesn’t ask you again for other credentials, saying “access is denied” or something, then go to your Services (Control Panel \ Administrative Tools \ Services) and restart the Workstation service. Try again, and Windows should ask you for your password again.
