Hi All,

Another question for today,

I have a 2008 server on a VMware ESXi box, when installed (By the last IT man) it appears to only recognise in windows a single core, I have adjusted the Vmware to have 4 cores but when I boot up the server again it shows only one core and is not recognising any more.

Any thoughts?

add another Socket (vCPU) rather than a core.

Have you upgraded the machine version and vmtools? The older versions do not respond to hot upgrades.
