WNetAddConnection2 returns windows error codes.
ctypes has a WinError function:

>>> from ctypes import *
>>> raise WinError(2202)
>>> from ctypes import *
>>> raise WinError(2202)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
WindowsError: [Errno 2202] Der angegebene Benutzername ist unzulässig.
>>>

In english: The username is invalid.

Even more convenient is to use the restype attribute of the
WNetAddConnection2 function:

def check_error(code):
    if value == 0:
        return
    raise WinError(code)

WNetAddConnection2.restype = check_error

This would raise the error automatically.
See the ctypes documentation for details!
