May be a silly question, but do you have Task manager set to one graph for all CPUs or one graph per CPU?<br />
<br />
Go to Task Manager-&gt;Performance select the View Menu-&gt;CPU History and see what it says there.<br />

I have a Dual Core Xeon 3.0Ghz CPU in a Wndows Server 2003 box. Device manager lists 2 processors in the &quot;Processors&quot; section. However when you go to task manager, it only shows 1 CPU. On an identical setup, but newer installation of Windows Server 2003 on another box, it sees both processors, no problem. How would I get Windows to use both processors?

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
