A customer has a Windows 2000 PC with the free version of AVG
installed. He does not have a software firewall (either third-party or
the Windows XP one). It is configured to send and receive email using
Outlook Express.

Everything has worked perfectly until recently when one PC cannot send
email any more, although it can still receive it. He is getting OE's
"cannot connect - timed out" message.

His other PCs, all configured with the same POP and SMTP servers and
the same SMTP-logon username and password, work fine. They all use the
same internet connection via a router.

I've established from OE's SMTP log and by doing "telnet smtp-server
25" that the SMTP server is not responding - when I connect to his
server using telnet I get a sign-on message from the server whereas he
doesn't.

Unfortunately the POP and SMTP servers are set up not to respond to
pings, so I can't use that to diagnose the problem - to determine
whether other PCs can ping the SMTP server when his can't.

Has anyone got any suggestions. He's not aware of any changes that
he's made to the PC. I've left him removing AVG temporarily to see if
it makes any diference.- Hide quoted text -

Why? It's clearly not an OE problem, given the results of telnetting
from that box to the SMTP server.

To the OP: long shot,but check there's no firewall blocking it, no
hosts file blocking it, and nothing stupid like new.net rerouting the
DNS queries to their servers. Actually, have you checked the DNS
server entries are correct?
