Windows advanced server and .net and the like are for real server use, load balancing, active directory services, dns servers, the type of stuff that you set up and leave running not set up then go play some quake hehe. unless your running a pretty advanced home network you will never use any of the features in it
Yeah, running the server version of an OS for use as a workstation sounds a little excesive, and if the services are needed that are utilized on the server, you can't turn it of or... no services. Seems a little odd. And yes Windows .NET is still in beta stages. And it seems like the Windows 2000 Server version should have the same stability as 2000 Proffesional, or even a little less due to the fact that it unaviodably will have more services than just a workstation OS.
