Hi

Dell GX270 / XP pro

We've had 3 machines in 2 days in which ctl-alt-del forces the machine
to reboot rather than bring up the login screen. The fact that this has
never happened before and now has started makes me suspicious that one
of the students has found a way to trigger this! We have a bios setup
password so they aren't getting into that (so far as I know LOL), and
they shouldn't be able to access system settings either.

Just a long shot, but has anybody out there seen anything like this before?

Hi Andy.

Having fun with the students again??

I don't really know what is happening offhand but I would try booting into
safe mode to see if it still happens and if it does not then they may have
installed something on the computer. You could also try to use another
computer to access the problem computer remotely to see what shows in Event
Viewer and for running processes. You can use Computer Management and
msinfo32 to view other computers Event Viewer and processes. I also like
psexec from Sysinternals to get a command prompt of a remote computer on my
admin desktop if you have never tried that. If Remote Desktop is available
on those computers then that may be another option to connect to see what is
going on and possibly even run a spyware/malware scanner that way. It is
great that you are using cmos passwords and such but it may not be that hard
to crack those passwords with free utilities since I assume these students
have physical access to those computers. Good luck. --- Steve

I've made progress with this - it booted into safe mode but not safe
mode with networking. Then I noticed that the date was set to 2099 and
the time zone to Tonga! Put this right and hey presto it boots! Little
horrors... Got to be alert for that one.

That's a new one for me that the wrong time caused a reboot when trying to
logon. Good job tracking it down. --- Steve
