Memory Usage

I read somewhere that SQL Server, SE only supports a
maximum of 2GM of memory because of the limitation
imposed by Win2K Server. If I have 4GB of memory in my
Win2K Server, does this mean that only 2GB is actually
being used or is the 4GB used?
Thanks

I have 4GB in my server and it only actually uses 1.7GB and believe me, on
my server it would be using more if it could.
