Evan,

>Have you heard of people running NT server as their workstation OS?

My main development machine at home is running NT Small Business Server (NT4, Option Pack, Exchange Server, Proxy Server, SQL Server) and works great as a workstation for web and VFP development, finances, word processing, internet browsing and Outlook email.

Of course the only other computer accessing it is the family machine upstairs, just for proxy internet sharing and storage to shared drive f:, so the load on it is very light.
