I'm running a Windows 2000 server. It currently has more then 8GB of memory in it but the OS only see 4GB. What can I do to get it to see the full amount of memory? Also if I need to upgrade to advanced or datacenter is there a way for to do that? I've heard they both see up to 64GB of RAM. But I have to use some special switch for it to work. I'm having problems right now with my terminal services.
