Dual-Homed Small Business Server Will Not Receive Internet Mail

• Microsoft BackOffice Small Business Server versions 4.0, 4.0a, 4.5

SYMPTOMS

When you attempt to connect to an Internet service provider (ISP) to download Internet e-mail using the SBSETRN /l command, no mail is delivered and the mail remains in the ISP queues.

CAUSE

A dual-homed Small Business Server computer with each network card configured to connect to a different network can cause this problem. If the first network card is configured, and then a connection and signup is made to the ISP, the first IP address assigned to this card is registered at the WINS server at the ISP. Adding an additional network card with an IP address from a different network will cause a connection to the ISP to be unrecognized at the ISP because the original IP address is registered at the WINS server.

RESOLUTION

Change the second network card to an IP address with the first octet set to the same as the first network card. For example, if the first network card is 10.0.0.2 and the second network card is 26.10.10.5, change the second network card to 10.10.10.5.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.
