Answer 1

The 64bit versions of the windows xp or windows 2003 operating system which are required to use the 64 bit versions of dot net framework 2.0.  You find info on the 64bit  versions of the framework here.

Answer 2

Windows XP and Windows 2000 are most commonly 32 Bit OSs. So they are 32 Bit configs. But there are 64 Bit versions of them i.e. Windows XP 64 Bit. The advantage of 64 compilations are more memory can be addressed, more registers ( GPRs and SSE/SIMD ) are commonly available on x64 platform, faster calling convention like fastcall etc.
