We are upgrading a server machine. This server is only a domain controller for a little domain (with 6 Windows XP client machines) where users do logon to access internet and some shared folders, and use some softwares. The DC is also their DNS for internet access (it simply uses forwarders.)
We want to upgrade to Windows 2003 (supposedly to Enterprise edition) and as we are upgrading the hardware at the same time, we have the choice of an Intel 2.8 MHZ or and AMD 3400+ 64bit.
As the server is not supposed to need installation of many softwares, we guess we won't face installation problems, but I want to ensure that:
1) Having a 64bit CPU doesn't mean having problem finding appropriate softwares.
2) Norton Antivirus Corporate Edition can be installed and work on such a system.
3) The AMD 3400+ 64bit processor is supposed to be faster than the Intel 2.8MHZ 32bit processor.
Any furthur recommendations would be so worthful to me.
