The CPU use for this SBS2003 server constantly hovers around the 50% and I get alerts to say the use is high. It is a new HP server with Xeon 3.0Ghz processor and 1Gb memory. It only supports 5 workstations and I have other servers of a similar spec and do not show the constant high use even outside business hours.
The process that seems to take the resource is the System - 4 process. I would welcome an approach to tackle the problem.
