We have a high speed DS3 connection to a remote location. One of the servers there is for hosting e-mail archiving. After a period of inactivity, the archive client reports a "server time-out" error. The subsequent tries are successful. We have also noted that the first ping after a period of inactivity is dropped but subsequent pings are flawless. What causes this?
I don't think it is an ARP issue because the destination server is a member of the domain and is very chatty. The routers are routing other traffic continuously to the same subnet so the ARP tables should be current.
I'm not sure what to look at next. Help!
Thanks!
