I have Windows 2003 SBS, we have a boat (ship actually) that fishes in the Bering sea. The boat needs to connect to our system to transfer files. Previously we were using our LInux firewall/server to connect to the system but we installed a new W2003 server and decided to have the boat connect to that server since we are now on Exchange for email. The I setup Exchange for pop3 access becasue the boat computer only has XP Home. Testing in the office seemed to work well but when the boat's at sea the connection speeds are really, really bad. The interesting thing is that if the boat sends an email with even a tiny attachment to an internal email address it will come back with a "transport unavailable" message. They are able to send just messages without attachments and they are able to send attachments to an external yahoo account. I don't understand why it has problems with sending attachments to internal accounts. Rather than using email I setup a share on the server so they could just \\10.0.0.2\boat and copy files there but the window never comes up. So, my first question is why the issue with sending attachments to an internal address but not an external one. 2nd, is there a way to optimize settings on the modem/ras? I can return to using the Linux server for connection though I would've thought a direct connection to the W2003 server would work better. Thanks.
