Why can't I log in to my computer? (error 5 / 1326 / 1327 / Login failed.)
Many users experience problems logging in to host computers.
An error 1326 or error 5 indicates that you are incorrectly entering your Windows/Mac user name or your Windows/Mac password. Error 1327 usually means you entered a blank password (that is, you did not enter any password at all).
