Does Win 2008 R2 still have 32 bit edition?
Solution 1:
As of Server 2008 R2, Microsoft is no longer shipping 32-bit versions of their Server operating systems. Yes, this does indeed put a maximum version limit on 32-bit only hardware! We can't upgrade our Domain Controllers to R2 because of this, we need new hardware for it. Those old Pentium 4's won't handle 64-bit.
