_WinAPI_ReadDirectoryChanges Error 58

[SkysLastChance 34]

When running the _WinAPI_ReadDirectoryChanges example on a network folder. I keep getting this error.

How can I tell what permisions I need to run this example on my netowrk folder at work?

It works fine when I run it on a local  drive folder. 

#include <APIFilesConstants.au3>
#include <Array.au3>
#include <AutoItConstants.au3>
#include <MsgBoxConstants.au3>
#include <WinAPIError.au3>
#include <WinAPIFiles.au3>
#include <WinAPIMem.au3>

Global $g_sPath = "J:\Folder\SubFolder1\SubFolder2"

Local $hDirectory = _WinAPI_CreateFileEx($g_sPath, $OPEN_EXISTING, $FILE_LIST_DIRECTORY, BitOR($FILE_SHARE_READ, $FILE_SHARE_WRITE), $FILE_FLAG_BACKUP_SEMANTICS)
If @error Then
        _WinAPI_ShowLastError('', 1)
EndIf

Local $pBuffer = _WinAPI_CreateBuffer(8388608)

Local $aData
While 1
        $aData = _WinAPI_ReadDirectoryChanges($hDirectory, BitOR($FILE_NOTIFY_CHANGE_FILE_NAME, $FILE_NOTIFY_CHANGE_DIR_NAME), $pBuffer, 8388608, 1)
        If Not @error Then
                _ArrayDisplay($aData, '_WinAPI_ReadDirectoryChanges')
        Else
                _WinAPI_ShowLastError('', 1)
        EndIf
WEnd

 

Edit:

It seems I would have all of these as permissions.

I feel dumb. RTFM

"If the buffer is greater than 64 KB and the application is monitoring a directory over the network, the function fails.
This is due to a packet size limitation with the underlying file sharing protocols."

64 * 1024 Byte = 65.536 Byte 👍🏻

P.S.: I’m currently binging The Office on Netflix, at the end of season 6 😉

If you made it to season 6. I would be willing to bet it won't be the last time you watch it. I have lost count on the number of times I have watched it all the way through. Majority of people say it drops off after season 7. However, I love them all.
