Add 2nd CPU - OS Rebuild?

[chez]

If you add a second processor to a Xeon server, would you have to reinstall the OS (Server 2003 Standard) in order for Windows to recognise the second CPU?

I know you had to rebuild when changin from a standard P4 to a Hyperthreading P4 on XP..

Thanks

Nope. And neither did you need to when installing a Hyperthreading CPU.

Sweet. I'm sure I remember XP not showing 2 CPUs in Task Manager when I got my first HT CPU??

Must be going mad!
