Hello,

Here is the situation.

My client has a Dell Latitude C600, running Windows 2000 Professional. He has an integrated NIC and Modem combo card. The NIC is used at work with a cable modem/LAN. The modem is used mainly from home, obviously with a dial-up account with AT&T's Worldnet. The mail server is with another independent company (independent of cable or AT&T). When using Cable/LAN he has no problem sending or reciving mail using either Outlook or Outlook Express. But the problem arises when he uses modem and dials into Worldnet. He can't send mail with either Outlook or Express, he can only receive, either at home or work. We tried another dialup account, problem wasn't solved. Another user has same computer, same OS, same everything, except for the dialup account, he has no problems. I uninstalled TCP/IP and reinstalled it, problem wasn't solved.

I added SMTP service to Windows 2000 Add/Remove programs components and changed the SMTP server in Outlook to 127.0.0.1, and sent a test message to myself. I received it the next day. I downloaded the latest updates from Microsoft's windows update, latest drivers from Dell, still no help. I can ping the mail server. I spoke with AT&T, they haven't made anychanges to their network. Anyone out there have a clue to what else I can do to fix this. Any help is appreciated. Thank you.

I already tried to Technet...no help there. As for sending it after a particular time...it works fine on a cable modem. With the cable/LAN its instantaneous. The dialup is where it doesn't function properly.

Everything checks out. I am connecting to an independent mail service provider using dial-up account with ATT. It was working fine 3 weeks ago, now its not. No user is having this problem except this client. Other users are using a different dial-up account, would that make a difference? any help is appreciated. thanks.

by richard lane

This is a very common problem with dial-up accounts. The problem is caused by the firewall policies of the company hosting your mail server, not the dial-up ISP. Basically, unless you dial-up direct into their system, you are blocked from using the SMTP services, and can only access the receive functions. They do this to stop people from bouncing spam from their SMTP servers.

There are two solutions to this:
a) get your user a dial-up account with the people who host your mail service, or b) talk to your mail service provider and get them to open their firewall. The only way that b) is feasible would be if your dial-up provider (in this case Worldnet) gives your user a fixed IP address, which the mail providers can then add into their firewall policy and open it up for you.

Good Luck

I thought it was the fault of the mail service provider, but, other users use another dialup service to access the mail server and send/recieve mail with no problems. Can you think of anything else? Hardware?

Hi
Pls try the user in a diferant machine.
then try other users in hte same machine.
in this we may get ideas.

Thankx

Thanks for all your help guys. I really appreciate it. But we solved the problem. It was the ISP...ATT. We used someone's else's account and on another ISP and Outlook had no problem sending or receiving mail. A most interesting situation. Lemme tell ya. We are still not out of the boat yet, Next test is whether the mail is being sent on time. It sent to my hotmail account instantaneously, but we have to test other mail servers. I shall keep you guys updated. Thanks for all your help,sorry you haven't won any points, may be next time.
