We are running windows 2003 standard server on a older HPML150 server running as domain controller with 9 PCs local and 2 Pcs via watchguard branch office vpn. Single user setup hosted application on sql2000 SP3.
We have bought two new ML350 G5 servers with Dual Quad processors with 12Gb ram each One is these is to be new domain server and second to act as terminal server. We need to decide on whether to buy Windows 2008 standard 64bit edition to utilize 12gb Ram otherwise standard 32bit will only see 4GB as we were advised, We also have been given options to windows 2003 enterprise which supports over 4gb Ram also.
My question to all you experts is what to choose here since we would like to maintain domain name and structure intact and not have to redo all workstations setups maintaining current profiles and what would be our best choice for operating system and how to handle domain migration or making replica of exisitng and promoting it to be dc. Will step by step directions please we have not done any windows 2008 setup thus the hesitation.
