Yes, jhance is right!

PS) If you want more, go for Advanced Server (goes up to 8GB).

Win2K Advanced and Datacenter versions support as up to 64GB depending on the OEM and several other pieces.

Win2K Advanced supports 4 Processors out-of-the box, but 8 processors if it's an Upgrade from NT (don't ask me why).

Win2K Datacenter will support up to 16 Processors out-of-the-box (clean install), but 32 if it's an Upgrade fron NT.

This is probably an licensing / OEM kind of thing, so it's subject to change.

32 Processors x 2GB = 64GB, so probably the answer is 2GB per processor?

A wee bit of bad news. I got off the phone with an engineer from Microsoft about 2 weeks ago because we were have a problem with Exchange and there is a little known fact that is not published in your documentation. Even though Windows 2000 can see 4Gbyte of memory, it can only use 2Gbyte of it before paging to disk. Advanced Server does support more, however you have to edit the boot.ini and add /3GB after the boot line so that it will use more.
