Windows 2003 server WMi and SVCHOST problems

Hello

My Dell Server PowerEdge 2650 / Windows 2003 Server's evenlog is filled with events like

The WMI Performance Adapter service was successfully sent a start control.
The WMI Performance Adapter service entered the stopped state.
The WMI Performance Adapter service entered the running state.
The WMI Performance Adapter service was successfully sent a start control.
The WMI Performance Adapter service entered the stopped state.

I have no clue about how to solve these events and to get rid of those,
can anyone give me a idea of what to do?

What happens if I turn of the WMI service? do I need it? does the Remote Access
Controller need it?
