I think you slightly misunderstood my question. I HAVE Windows server 2008 standard on an HP server, but am using it as the main computer "peer-to-peer" with about 20 other computers. How many hours do think it would take for a good IT professional to set it up as a domain so I can play with the benefits that so many above have mentioned? Also, is there any downside other than the initial cost of setup?
