    I know SBS 2003 should be able to use two processors. I have a four
    processor machine but only one CPU is showing as being utilized.
    Is there a fix for this or do I have to rebuild the server?

  2. in devmanager, expand the 'Computer' entry, what does it say? (ie. which HAL
    is in use?)

  3. I'd also watch in BIOS Start See if they are all showing up on Boot.

    It says MPS Multiprocessor and the driver says Hal.dll
    windows task manager only shows one cpu.
    Is there another way to check to see if it is actually using more than one?

    Make sure when using task manager it's shows one graph per CPU ...

    The system is using hal.dll but should be using halmps.dll. How do I fix this?
