OK, to clarify some stuff here. It is a W2K8 web edition server running in a virtual machine so 1GB isn't the end of the world.
Scott, monitor the memory now and see how it is after a reboot. Does the free memory pick up where it left off or is it in fact cleaner?
If you have a question that specifically, ask Liquidweb. Like I said in the past, you need to get away from Windows Web servers
