INTRODUCTION
This article describes how to enable the ETRN command in conjunction with a dial-up connection in Microsoft Exchange Server 5.0. When you do this, you can send and receive e-mail messages through your Internet service provider (ISP).

In some scenarios, you might have a dial-up connection such as an Integrated Services Digital Network (ISDN) connection that is configured to your ISP. In this scenario, you may want to use the ETRN command in Exchange to retrieve e-mail messages at certain intervals.

Note You cannot retrieve e-mail messages by using the ETRN command unless your ISP supports this command.



Step 1: Configure the Windows NT Server 4.0-based computer to use DNS
To configure the Domain Name System (DNS) information on the Windows NT Server 4.0-based computer that is running Exchange Server 5.0, follow these steps:  Click Start, point to Settings, click Control Panel, and then double-click Network. Click the Protocols tab, click TCP/IP Protocol, and then click Properties. Click the DNS tab. In the Host Name box, type the name of your computer as it appears in the DNS namespace. The default DNS host name is the same as the computer's network basic input/output system (NetBIOS) name after the removal of the sixteenth hexadecimal character. However, you may want to configure a host name such as &quot;mail&quot;. In the Domain box, type the domain that your computer's host name appears under in your DNS namespace. For example, type contoso.com . Under DNS Service Search Order, click Add, type the IP address of your DNS server, and then click Add. Click the WINS Address tab, click to select Enable DNS for Windows Resolution check box, and then click OK.</li> If you receive the following message, click OK:

The new Internet host name is different than the computer name currently in use. You computer will now be known by one name on your local area network, and by another name on the Internet.

If the computer name is ever changed, it will overwrite this new host name and the changes will be lost.

</li> Click Close, and then click Yes on the following message that appears:

You must shut down and restart your computer before the new settings will take effect.

Do you want to restart your computer now?

</li></ol>

Step 2: Configure a dial-up connection to your ISP
