Is that lan a completely private lan with no connection to the outside world? If it has a connection to the outside, use ntp properly and have your server at least use some outside thing to configure to. If it really a totally issolated lan, then make the server orphaned, and the client just acts like a client, using the server as it time source. _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
