I misread your tone. Sorry. With all the talk of RIAA lawsuits flying around here that comment about a "Having a Legal Copy" probably set me off. The hurricane I just went through probably isn't helping my attitude any either. Again I apologize. I use XP Pro on my workstation too. I'll lay it all out for you. I have a VERY small network. By that I mean two machines. My XP workstation and my 2003 Server. I want choice B that you listed above because I am interested in doing animations with render cow running on the server (because that's the only other machine I have. I need it to be a web server for when I am developing and testing web applications). Yes I get your point about the network render. But it doesn't apply to my situation. I don't have that many processors. I just want my animations to render faster. I asked Lynn if Vue 4 Pro (and it's Render Cow) would work on 2003. But he got swamped and never answered the question. It may be a leap of faith on my part but I figured if Vue 4 would run on 2003 then Vue 4 Pro would too. I hope so because I am about to shell out the money for Vue 4 Pro based upon that. I haven't converted my server to a workstation. Vue works fine on it with the default installation. I probably wouldn't even be thinking about this if I had to convert to a workstation. I need the server for my work. Microsoft Action Pack Subscription http://members.microsoft.com/partner/salesmarketing/partnermarket/actionpack/actionpackus.aspx MAP is only $299 and gets you a developers copy of XP Pro, Win 2003, SQL Server 2000, MS Office, and a bunch of other stuff. It's a really great deal which Microsoft doesn't advertise much. Go to that link and check it out. My experience with 2003 has been pretty good. It seems to be laid out more logically. By that I mean things are easier, for me at least, to find. Fewer steps required to get something like create a user account, etc. Security has improved a LOT! Everything is disabled by default. If you want a service you have to enable it or in some instances install it. For instance no Blaster Worm if DCOM is off. I'm a web developer so having the .NET framework there from the get go is a plus. Admittedly a small one since all you have to do it patch 2000 to get it.
