Outlook 2003

I would like to know if there is a way to use an Outlook rule to send
something like a Net Send message to another computer. One possible
stumbling block is that we have the Messenger service disabled on our
machines, so Net Send itself will not work unless we enable that service.
For the few machines that the message would need to go to, we may be able to
turn on the Messenger service. Nonetheless, I would like to know if there
are any ways to accomplish this without needing to enable the Messenger
service.

You may be wondering why we want to do this. We have a mailbox that we
monitor for information on critical vulnerabilities. To decrease the
probability that a notification marked "Critical" will sit unaddressed for a
period of time until it gets noticed, we would like to setup a rule that
will fire off something like a Net Send message whenever a critical
notification is received. The Net Send command will cause a dialog box to
pop up in the middle of the screen on receiving computers. It's hard to
miss that! But, like I said, the Net Send command requires the Messenger
service, which we disable. Therefore, I would be interested in hearing any
suggestions regarding alternative methods of achieving the same basic goal.
