);

Parameters

Descriptor [out]

The security descriptor associated with the service.

Remarks

The Win32_SecurityDescriptor instance represents a SECURITY_DESCRIPTOR_CONTROL data type and contains a discretionary access control list (DACL) and a system access control list (SACL). For more information, see Access Control Lists.

If the SeSecurityPrivilege is not granted or enabled when getting a security descriptor, then only the DACL is returned in the returned security descriptor. For more information, see Privilege Constants and Executing Privileged Operations.

Examples

When retrieving a security descriptor in VBScript, be sure to "Security" and run as Admin, as shown in the following code snippet. Otherwise, your code may throw a permissions error.

Set objWMIService = GetObject("winmgmts:" _
  & "{impersonationLevel=impersonate, (Security)}!\\" & strComputer & "\root\cimv2")

Similarly, in VB.NET, be sure to set "EnablePrivileges = True" and run the Application as Admin.

Scope = New ManagementScope([String].Format("\\{0}\root\CIMV2", ComputerName), Nothing)
Scope.Options.EnablePrivileges = True
