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.
