What is the difference between the various versions of Windows Server 2003?

Title says it, what are the differences between Windows Server 2003, 2003 Pro, Enterprise, and datacenter and VLMs of each. Thanks.

I think this is what you're looking for

Thanks

Thats not all of the versions and it lacks a lot of info. They left out Windows 2003 Storage Server.

Storage Server, Web Edition, and Datacenter are all OEM only.

Unless your clustering standard is the best of the bunch. It lets you set up a domain (AD, DNS, NS, DHCP, etc.), host websites (IIS), run shadow copy.

It's worth noting that you cannot run MS SQL Server on Win2k3 Server Web Edition.
