NAS unable to send emails

Hi, I am setting up Navision and Commerce portal on Windows 2000 server without the active directory. Everything else seems to be working fine except NAS can not send emails out. I do not even see them queued up in Commerce Portal > Status area. When I stopped NAS, restarted and launched my outlook express client, I saw all those emails sitting in the outbox of outlook express. Outlook express then sent them all out. Any insight? TIA Jamal

Does nobody have an idea ? …

No Idea??? Im having exactly the same problem…funny though it worked as a clock before i setup a second nas to do emailing…
