>I was just reading Chapter 14 of Playing in the COM+ Sandbox in the book What's New in Visual FoxPro 7.0. It meantions several times that COM+ is part of the Windows 2000 operating system and that you must be using Windows 2000 to use COM+. The question I have been pondering is if your company is using Visual FoxPro 7.0 but are not planning to use or create COM+ objects do you need to be using Windows 2000? So does Visual FoxPro work ok with Windows NT?

You don't need Windows 2000 but as Craig points out it's more stable and faster in regards to COM.

COM+ is built-in to Windows 2000, where in NT you had to install the NT Option pack to get similar functionality. NT only supports a few of the COM+ Services through MTS mainly, but most of it is still there.

There's a difference between plain COM objects which is probably what you're thinking of and COM+ components that use the special COM+ services that Windows 2000 exposes. COM works in any environment - COM+ services work only on Windows 2000. This is a restriction of the OS obviously, not VFP...
