Cannot get past the logon screen

Co-worker had a problem with the Office Shortcut bar disappearing. Heard he had to change;

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Winlogon

which he did.

Need to get the registry back to normal, but cannot boot to dos. Using a SCSI drive, and haven't been able to boot and get to the C:\ drive.

Then, once I get there, how can I edit the registry from DOS

Hi, if the pc has not booted up,
then reboot and go to safe mode, (press F8 before the windows logo)
In safe mode, choose "Last known good configuration"

This will use the registry that worked the last time the computer had been booted up.

Hope I could help

Tried that. Still comes to a logon screen, that I cannot get by. (Logon on safe mode?)

Reset all the passwords with another bootdisk program (although there were never any passwords installed)

Another thing I noticed is that it appears to be loading the desktop. After hitting enter (no passwords enabled), a folder window pops open for a millisecond, and then disappears back to the logon screen

Sounds like a virus, or some malware.

In safe mode nothing in the startup is supposed to run, but that is not always true.

Have you tried VGA safemode also ?

I would install win2k into a different partition or directory so that you wil have tools to fix the main one.

I hope this helps !

After it boots up, connect to the registry from another computer on the network.  Set the Winlogon part of the registry back to what it should look like.  Reboot and try to logon again.

robrandon is dead on and the solution he mentions should work great (if you haven't disabled the admin shares for any reason (or remote registry)).  What value did the user change?  UserInit or Shell?  What was it changed to?  Depending on the specifics, there may be other ways to circumvent the self-inflicted problem.  Good luck.
