Hello. Whenever I try to log-in it says "Authentication Failed" in a pop-up box, but I know the username and password are correct. The problem came up after I tried to add a user and allow that person to use SMB. I restarted the computer and couldn't log into the computer or the SMB shares. Any help would be appreciated. I'm running YDL 3.1 on an iMac DV SE Thanks, Michael Ewald
