I have a server that is running Windows 2000 server. I dont know if it is just 2000 server, or advanced server, or datacenter, or any other type they might have out. Now I understand that for most purposes they are the same except licensing. However, my issue is that I need to free up some free space on the C:, and thanks to our SMS administrator, I have every available update that has ever been put out. So looking at the updates, I see some for each different type. I want to remove the non-crucial ones. So first can you tell me how to determine which version I have, and second can you tell me if I have say just regular Windows 2000 server, do I need the Windows 2000 advanced server updates, or datacenter, etc?
