Thanks a lot for the help!!!
This is no longer Excepting... But the Result is 0 and there doesn't seem to
be any data in the Buf structure or indication that there were results in
RtnLen... I get to debug this more.. YAY!!!

No, 0 is the error return that means the name was not found.
You shouldn't need to use LoadLibrary and GetProcAddress. ctypes does that for
you automatically.
winsta = ctypes.WinDLL('winsta.dll')
winsta.WinStationQueryInformationW( 0, session_id, 8, ctypes.byref(Buf),
BufLen, ctypes.byref(RtnLen))
If you have Visual Studio, you can try doing "link /dump /exports
\windows\system32\winsta.dll" to make sure it has that entry point.
