Can someone please explain how to enable my system to use 8GBs of RAM in win2003

It sounds like you are using the 32-bit version; the x64 version will find and use your 8GBs RAM. 32-bit systems are limited to about 3.25GB total memory. They do not have the registers to assign and use any larger amounts of memory.
