Re: VM Newbie…
First post in thread, point 1. SBS 2003 is a 32bit application so is limited to 4GB RAM. Having tons of memory (I am assuming this is what you refer to as RAM) in this case is really wasted. 32bit 2008 Server will also only utilise 4GB RAM.
Just a couple of points to keep in mind.
SBS 2008 may be worth looking at as a viable option since it is a 64bit application and it may like tons of memory.
