It is a local network. One client is wired (100Mbit ethernet) and the other is WiFi. > If they're remote, then ARP probably isn't involved unless you're having > issues finding your default gateway.

Unfortunately they have not been so far. Logs on the client show a request with no reply, logs on the server show no request coming in. It is unclear to me if an outgoing request would be shown on the trace when ARP resolution is incomplete. _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
