To determine what other W2K services are running, open a CMD window and type
NET START You might want to look for services like "Task Scheduler" or "Indexing Service" which can easily be stopped via NET STOP "Task Scheduler" NET STOP "Indexing Service" I'm not exactly sure about all the W2K professional services that can be stopped, but things like Messenger and Alerter can always be stopped.
