Why does my server 2003 guest only see 1 processor core on a Core i5 Ubuntu 11.04 host system?

Last Modified: 2013-03-29
I have a server setup with Ubuntu 11.04 running the latest version of Virtualbox 4.1.4.  The server has 4gigs of ram and a Core i5 processor with 4 cores.  I have a guest system setup with Windows Server 2003.  I have setup the guest system with 2gb ram and access to all 4 cores.  When I load the os up, the task manager only reports one processor core.  But the virtual machine status shows that it is giving access to all 4 cores.  Is there some sort of limitation in Windows server 2003 that would prevent me from seeing all 4 cores?
