Can the 32-bit version of Windows Server 2003 use more than 4GB of memory if on a 64-bit platform?

We recently setup a Windows Server 2003 R2 SP2 based server on a 64-bit Intel XEON platform.  There are 2 quad-core processors and currently 4GB of memory (2 x 2GB).  Due to the software that the server was pruchased to run not being 64-bit compatible, we are running the 32-bit version of windows.

All-in-all we are running just fine - I checked with Intel before making the purchase - the processors are backward compatible.  

We may need to utilize more memory - the server will ultimately host as many as 8 TS sessions running a program that is rather hefty on memory usage.

Can we go beyond 4GB of physical memory and will there be a benefit of doing so?

No. To use more than 4Gb you need both a 64bit OS AND 64bit hardware
(The 32bit Enterprise version can use more than 4Gb with the /PAE switch with a 36bit addressing fudge).
