Here is an example on how to use performance counters to monitor and concole notify upon a threashhold being satisified. Naturally, it would be very easy to add memory, network utilization and smpt email alerts to the following vbscript example with ease.

'example on how to use performance counters to monitor and notify to 'console of excessive processor usage. an alert to console is 'prompted if processing exceeds 90% on ten successive measurements.
