Windows Vista x64
Have always used automatic login before. Recently added second administrator account so login screen now appears. When correct password is entered, the computer says incorrect username or password. This is true for both accounts. Can not get past the log in screen at all. Can not log into the system.
When the password has been used to authenticate administrative tasks previously, it has been fine. Don't believe I have ever used the login screen before so this issue may have existed before the second account was created and only made apparent by this addition.
