The problem is that no-one can login. When logging in to the machine the desktop image is displayed for less than a second before the 'Logging off ...' message comes up and we are back to the login screen.
The same happens in 'Safe Mode' logging in as any user OR Administrator.
After the first login attempt after turning the machine on there is an ochre coloured box which appears in the bottom right of the logon screen. This box is headed up 'Log on Authentication' with a yellow padlock to the left. Below that is 'Please authenticate the user that you wish to log onto the system'. Below this message is a key on the left and 'Cancel' on the right.
The only thing I can see to do is to reformat BUT before I do is there anything else that might help if I attach the hard disk to one of my own machines?
