The following VBScript code example creates a share folder and then gets the value of the access mask in the security descriptor that secures the share folder.

VB
Copy 
strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" & strComputer _
    & "\root\cimv2")
Set objNewShare = objWMIService.Get("Win32_Share")
Return = objNewShare.Create _
    ("C:\Temp", "TestShare", FILE_SHARE, _
        MAXIMUM_CONNECTIONS, "test share")

If Return <> 0 Then
          WScript.Echo Return
