Routine Description:
|
|||
|
|
|
|||
|
|
Uses Win32 LoadLibrary and GetProcAddress to get pointers to functions
|
|||
|
|
in Netlogon.dll that are called by Msv1_0.
|
|||
|
|
|
|||
|
|
Arguments:
|
|||
|
|
|
|||
|
|
None.
|
|||
|
|
|
|||
|
|
Return Value:
|
|||
|
|
|
|||
|
|
None. If successful, NlpNetlogonDllHandle is set to non-null and function
|
|||
|
|
pointers are setup.
