RESEND for the 4th time

[Lona]

Hello all,
I face a very strange issue with my Win 2000 Pro+SP3 When
I lock the machine and un-lock it again it logs off
instead of returning back to the desktop(it
go back to the login screen).Also sometimes when I
working suddenly it logs off.it is on a network and logs
on to a Windows 2000 Domain and has a permanent
connection to Internet through ISA Server 2000 client.

I'm assuming its rebooting here, if so try

right click on My Computer icon
select Properties
select Advanced
click Startup and Recovery button
untick Automatically Reboot

now if it crashes and reboots again it will blue screen and the last item
showing on the blue screen is often the item that caused the crash.

Have you checked the Event Viewer? What if any entries are in there?
