Kim,

Thanks for the response, however, I think it was pretty
clear that we covered everything you mention when the
accounts were checked, double checked and sending mail
failed, then new accounts were setup on a different
computer and all was fine. This problem only persists on
the win 98 box with outlook, even accounts in outlook
express on this machine fail.

Any other suggestions?
