Ctrl alt del

Is there a way to lock my workstation in such a way that ctrl+alt+del does not give you the option to end a task. I have a small program in win98 that catches all keypresses even system keys, so nobody will be able to enter win98.
In win2k this does not work (off course). Is there an alternative?
I have seen a program called locked! that does have a certain way to do this by restarting itself when ended within the task screen.
Any suggestions?

you cannot end a task when a NT/win2k Box is locked.
So I'm not sure what your problem is

You could replace MSGINA.DLL with your own version. See http://www.microsoft.com/WINDOWS2000/techinfo/administration/security/msgina.asp for more information.

to franka: sorry for not being clear; while the workstation is locked, no task can be ended of course, but the workstation could be unlocked by an adminstrator on the domain, which is (in some cases) undesirable; so I need an different "Lock workstation" function
to steveGTR: I'll have a look at that

Just a reminding hint; Nobody except the logged on user can unlock the workstation. What an administrator can do is only to log out the logged on user. If yuo want to protect administrators from doing this, it would first of all be quite a hard task to do programmatically, and second - if the admin wants you logged of, he could just turn of the main powerswitch to shut the system down.

No offense, just trying to make a point here... :)


cheers!

Agreed, but the beforementioned tool Locked! would even prevent access in this case, as upon reboot, the program would still be locking the workstation.
I know it's a far fetched situation, but sometimes overzealous paranoia is safer than trusting admins or Microsoft for that matter ;-)

what about deleting the domain admins from the local admin group on these workstations (at least temporally with a batch job that remove/add the group)?

by the way:
it is an essence of NT security that you can always press ctrl-alt-del to get the security dialog, and there is no way to capture these key strokes.
