That implies you've got dual Xeon processors with Hyperthreading enabled.
That might be confusing Windows into thinking you've got 4 processors. How
many processors is the verion of w3k on that system licensed for? It could
be ignoring processors for which you don't have a license. Of course, this
is pure speculation on my part...

Try disabling Hyperthreading in the BIOS so Windows only sees the 2
processors you actually have, and see what happens.
