Problems like this can be solved with dependencywalker (google for it).
The walker displays binary dependencies for images.
Using it I found this: win32net.pyd from build 204 does *not* use the
LsaLookupNames2 function in advapi32.dll. However, win32net.pyd links
to netapi32.dll (among others), and netapi32.dll links to advapi32.dll,
using the name LsaLookupNames2. This was on WinXP.
On win2k, netapi32.dll will not link to advapi32's LsaLookupNames2 -
otherwise it would not work.
So, your exe *should* be able to run on win2k - except if you distribute
XP's netapi32.dll with your exe (I've checked this with a trivial
py2exe isn't very good at determining which dlls belong to the
operating system, and so must not be distributed - netapi32.dll is such
a beast. You should remove netapi32.dll from the dist directory, and it
should work on win2k.
And sorry for the false alarm on the threads you mention above ;-)
