First, I know just enough about 2000 Advanced to be extremely dangerous. I have a rack of servers where I have split out the different machines as web server, mail server, data server, etc. This is my home setup. I am retired from the profession due to a disability. First, I am not hosting any mem/data intensive things so I am way underutilizing the servers. Secondly, I am killing my electric bill and my wife is figuring out how to get me to eat rat poison. Sooo, I need to consolidate. I am not worried about load because everything I have, except PDC, is a Dual Xeon P4 and are mirrored. My ideal goal would be to bring everything down to one server for now and just max out the memory. Like I said at the beginning, server admin. is not my thing so be patient with me. My question(s) 1) Can a machine that I set up as a PDC act as another type of server (i.e. data, web, app, etc.). I am not sure if once you make something a PDC (also my enterprise CA) that I cannot use it as an IIS, SQL, etc. server. Am I wrong? 2) This is a stupid one and I was just wondering if technology has fixed this. I know I can set up a machine to dual boot but can I set up a machine to run 2 OS's concurrently (e.g. at the same time). For instance, can I have, on one box, Server 2000 and XP running in different memory segments at the same time so I can be writing a doc in XP and Advanced Server 2000 is still hosting web and mail? My understanding is the answer is 'no', but I have been on disability for over two years now and something might have come along to address this issue. I like to use XP for my personal desktop and applications. Any advice is greatly appreciated and I will sacrifice a small furry animal on the next full moon in your honor.
