Either use Windows Server 2003 x86 Enterprise Edition (if you want to see the extra RAM) or the Windows Server 2003 x64 Standard Edition.
>From memory GPMC doesn't run on x64 (But I could be mistaken about that). No issue with AD itself on x64 - runs fine. Actually you get 4GB per user mode process (rather than 2GB out of 4GB), so you can sustain a larger AD .dit/database.

In doing so I want to add extra RAM to the box. If I put 16GB RAM into the new box and install Server2003 Std 32bit what will the system do? Simply ignore the extra RAM? Any harm in doing this? If it's better to use Server2003 Std 64bit to properly see the RAM is there anything that changes in AD? My gut tells me 99% this is OK and I can't find anything online stating otherwise but I want to be sure. These boxes only do AD so I don't have to worry about any external apps being 64bit.
