How to get access control of C:\Windows\System32\inetsrv\config folder using c# asp.net

Question

I am trying to give permission to C:\\Windows\\System32\\inetsrv\\config folder. But when I use the below code it throws exception "Attempted to perform an unauthorized operation."

 string desktopFolderPath = @"C:\Windows\System32\inetsrv\config";

        FileSystemAccessRule iis_iusrs = new FileSystemAccessRule("IIS_IUSRS",
           FileSystemRights.FullControl,
           InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit,
           PropagationFlags.None,
           AccessControlType.Allow);

        FileSystemAccessRule networkService = new FileSystemAccessRule("NETWORK SERVICE",
            FileSystemRights.FullControl,
            InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit,
            PropagationFlags.None,
            AccessControlType.Allow);

        System.IO.DirectoryInfo desktopFolderDirectory = new System.IO.DirectoryInfo(desktopFolderPath);
        DirectorySecurity directorySecurity = null;

directorySecurity = desktopFolderDirectory.GetAccessControl(); -- **Exception**
            directorySecurity.AddAccessRule(iis_iusrs);
            directorySecurity.AddAccessRule(networkService);
            desktopFolderDirectory.SetAccessControl(directorySecurity);

Please help if anyone can. Thanks in advance.

Go to the folder path Properties and make sure it Read-only check box is unchecked.

This may be of some help: link

If it doesn't, then try sharing the folder.

By the way it is a system folder, It may not be accessible, so try hosting pages in C:\\inetpub
