Generally, each network has one box that syncs with an external source and all other local boxes sync from that one. The minimizes the load on public time servers and makes for a flexible system. *nix boxes can sync to the local time server using rdate or NTP. Assuming the local time server is capable of running SMB, Winboxes can use the "NET TIME" command or an NTP utility. I think the NT or 2k resource kit includes a timeserv utility to sync those machines with a time server, probably using NTP. To answer your question, NTP uses port 123, TCP and UDP. Your router should NAT the packets so you don't have to worry about port forwarding. Tony - -- Anthony E.
