| ### LANs with WAN Links to Remote Sites The following figure shows a LAN that incorporates several remote nodes by using WAN links. DTS Configuration - LAN with WAN Links In this configuration, follow the basic recommendations for a single LAN, but also adhere to these rules: · Configure servers at remote sites as global and courier servers. · The LAN should have a minimum of three servers. · If you are using a single time-provider, locate it at one of the global servers on the LAN, rather than at a remote server. The network configuration that results from the preceding rules concentrates the servers on the LAN, so clock skews are kept to a minimum and the service is not dependent on remote nodes that may be physically inaccessible to the system manager. Each remote clerk node synchronizes with the global servers to satisfy the minservers attribute setting. ###
