Hi,

I have a W2000 computer that when i log on as any user, even administrator,
it starts to log on but before the taskbar appears it does the log off
automatically and returns to the log on screen.
I can't access the computer, i tried to do CTRL+ALT+DEL to call task manager
while it is logging but it starts to log off before i have the opportunity.
I suspect a virus but i used a updated rescue disk and it detects nothing, i
tried to find a virus with such behaviour and i could not find it.

Has anyone have any idea? i don't think this could be a W2000 problem...

Thanks,

João Guerra

This typically happens when hard disks are changed. Before you
change disks, delete any inappropriate or non-existing devices
as per Step 2 below.
1. From dos, copy userinit.exe to all the other hard drives
This should allow you to log in.
2. HKEY_LOCAL_MACHINE/SYSTEM/MountedDevices/:
delete all keys which look like "\DosDevice\<DRIVE_LETTER>:"
3. Point KEY_LOCAL_MACHINE/Software/Microsoft/Windows NT/Current Version/
Winlogon/Userinit to the correct location of userinit.exe

You can also edit the registry of the problem machine via
a network connection to point the paging file back to where
it belongs:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\
Memory Management
