   Windows NT Workstation supports up to two processors in a symmetric 
   multiprocessing environment.

According to that document NT Workstation can only support two
processors, but NT Server can support four processors.  I wouldn't be
surprised if embedded in the code there was some sort of check:
	if (ms->makemoremoney->is_nt_server == TRUE) {
		/* support four processors */
	}
