MSN Messenger on a LAN
6 Answers
I use MSN Messenger from my home LAN to communicate with my partner, but for some reason, am unable to 'Send Files or Photos'. I know several other, very techie, people who also have the same problem, but can find no answer to it. Please don't suggest that I ask Microsoft, as they want me to pay �40 for any technical support. Can anyone give me any reasons for this? I am not behind a firewall, and am using Windows ME an the gateway computer to a network including one other machine, running XP Pro

From your question I assume that ME is being used as an Internet gateway of sorts, ie. you have your machine, the XP machine and the ME machine on the LAN, with the ME machine connected to the Internet, forwarding requests from you and the XP box?
The Microsoft IM protocol states that when sending or receiving a file, the sending machine issues an invitation and then opens a port for the receiving machine to connect to and pull the file if it accepts the invitation. This would insinuate that if you can receive files your machine has no problems opening outbound ports, and if you can't send files, it's because the recipient's machine can't connect to the port on your machine, either because of a fault at your end, or because they can't open outbound ports. You mention though that it works from the XP box, so the problem is most likely at your end with ME.
So, how does the XP machine connect? ICS? Wingate? A proxy? SOCKS? Have you got inbound port ranges mapped through to the XP machine? Do you use any firewalling software on either box?
