Windows XP Home Keeps Logging Out instantly after Loggin In

[Guest]

Help, my copy of Windows XP Home keeps logging out instantly after I logged
in, whenever I logged in, the login sound plays then just a milisecond or so
after, a log out message is displayed and the logout sound plays then the
login screen is redisplayed.

Please help. I use this computer for business and I do not want to reformat
the entire hard drive as it contains very vital files that are needed for my
job.

Thanks

--or--

The problem may be an incorrect system drive letter. With a networked
machine, open the registry and connect to the problematic machine and
navigate to:

[MACHINE_NAME\HKLM\SYSTEM\MountedDevices]

and delete all values that look like this:

\DosDevices\C
\DosDevices\D
\DosDevices\E
and so on

When finished, make sure you disconnect the machine from the registry. There
are other ways to gain access to the registry if you cannot connect to the
problematic machine via networked Registry. Please let me know if you need
information on how to gain access to the Registry if you cannot by a
networked registry.
