Problem

You are running under Windows Server 2003. Even though your server has 2 CPUs, ERSDE Server Configuration reports that 4 CPUs have been detected. The exact message is:

This license Key is limited to 2 CPUs and 4 CPUs have been detected on this workstation.

Solution

In some conditions, on a Windows Server 2003 based computer, Windows incorrectly reports the number of physical processors. A hotfix from Microsoft is available to resolve this issue:

The number of physical hyperthreading-enabled processors or the number of physical multicore processors is incorrectly reported in Windows Server 2003
