Didn't know that, so that has to be changed for sure

 /*****************************************************

+HRESULT WINAPI ADsGetLastError(LPDWORD pError, LPWSTR buffer, DWORD
buflen, LPWSTR bufname, DWORD bufnamelen)

>Returning E_POINTER seems pretty wrong.

In the documentation on http://msdn.microsoft.com/en-us/library/aa772183(VS.85).aspx
it is listed as one of the possible return values. Of course one could also return E_NOTIMPL or E_FAIL etc, but for a stub this seemed like a good choice to me as well, the application (Dameware) doesn't seem to bother what is returned, it starts up just fine
