Hi Rob,
it seems that changing the screensaver appeareance from animation to an
alert message isthe best for me. It may be difficult to terminate when there
exists password protection.
You can find the clear screen saver in Resource Kit CD of windows 2000. It
works as an NT service and I can see my animated icons working in the task
bar, so it is continuously updating the screen, I can also see net send
message popping up on the screen.
Regards,
Tolga
