Windows ALERT

Ok, I have a wireless RIM device and I want to be able to have my Windows 2000 servers e-mail me on this wireless device if there is a problem ex(processor usage time peak, etc). Is there any free software that will alow this? I found a little command line utility to monitor TCP ports and e-mail me when they go down, but I’d like to be made aware of major OS issues as well.
Any help is GREATLY appreaciated.

Thank you
