Look at the dlls that were gathered (in the build directory, or for
a --onefile use PyArchiveViewer on the exe). My educated guess is that
you're picking up an MS dll that should be excluded. You're picking up
the XP version, which relies on the XP version of ntdll.dll. Exclude it,
and a Win2K box will load the Win2K version and all will be well.

Excludes of this nature are hardcoded in Please let me
know what it is, and I'll get it into the next release.
