If you try to install MOSS 2007 on Windows Server 2008, you are going to get an error that there is an incompatibility. To install, you need SP1 for MOSS.
I usually download everything from MSDN Subscriber Downloads or install from MSDN DVDs. Of course, there is not a version of MOSS 2007 with SP1 already slipstreamed on the subscriber downloads.
You could slipstream SP1 yourself, but it turns out there’s an easier way. First, install the trial version of MOSS 2007 with SP1 (32 bit or 64 bit). After you install the trial version, upgrade from the trial version.
