It's a Dell PowerEdge 6800 with (2) PROCESSOR, 80546, 3.0G, 8MB, XEON POTOMAC, 667, C0 so it's 64 bit hardware, but running the 32 bit version of windows 2003 R2. Would that be an issue running the 32 bit version of the 2003 R2 Enterprise vs. the 64 bit? My understanding is that Enterprise version supports I think up to 64GB of memory? If so, can we just get the 64 bit and don in in place upgrade or something?
