I am doing my first attempt at a 64 bit Portal and learned the hard way that a 64 bit Xeon Processor Server is not the same as a 64 bit Itanium Processor Server. Both are Intel, both are 64 bit.
My open end question is, does anyone have a pure 64 bit platform and what are they running it on? I was under the impression that as long as my hardware and OS (Windows Enterprise 64 Bit Edition) were all on the same level that everything else would fall into place. Now I know this is not the case.
