To set the DNS dynamic update properties for use by the current DHCP  server.     Syntax:            set dnsconfig  [Update(0|1)] [Lookup(0|1)] [NonDyn(0|1)]    Parameters:            Enable         - 0=Disable DNS dynamic update of DNS client                           information.                            1=Enable DNS dynamic update of DNS client                           information.             Update         - Forward and Reverse name lookup can be                           updated when a client acquires a lease.                            0=Update according to client request.                            1=Always update forward and reverse lookups.            Lookup         - Discard forward lookups for clients when                           lease expires.                            0=Disable these lookups, 1=Enable these                           lookups.             NonDyn         - Update DNS information for clients that do                           not support dynamic updates.                            0=Disable these updates,                            1=Enable these updates.    Notes:         This feature is supported only for Windows 2000 Server,                 Windows Server 2003 and Windows Server 2008. When dynamic                 updates are enabled, the DNS server used by the DHCP                 server to submit updates is based on DNS servers configured                 for TCP/IP client properties for network connections.        Example:       set dnsconfig 1 1 0 1                   This command enables dynamic update of DNS information                 by the DHCP server and configures updates to always be                 made for both forward and reverse lookups. In addition,                 the option to discard forward lookups when leases expire                 is disabled and updates for non-dynamic clients are                 enabled.
