Email problems

[calpilot]

I have a small (3 computer lan) and am using outlook 97 on the networked computers. The system has worked fine for about four months but recently the networked computers cannot send email.
The error: 'No transport provider is available to send to this recipient.' comes back everytime.
I'm on DSL with sbcglobal.net and mail from the server works fine.
Anyone have any ideas?
TIA,

Can you ping the other boxes ?
maybe your connections betwen them is broken (cable unplugged, etc)
Think about the time when it last worked and ask yourself ..have I done anything different since then? like add or remove programs, make changes in your configuration...What kind of OS are you using on the boxes...
Haven't run in to many real world email problems would be beneficial to both of us to learn whats going on...I'll try to help ya' where I can school,work and holidays are taking up alot of my time....but I'll do my best.

Also when you say the mail from the server works fine -What do you mean- The LAN "Server" or something else.
