SYMPTOMS

When you start Internet Mail Service, you may receive the following event in the Application Log of the Microsoft Windows NT Event Viewer:
Event ID: 4007
Description: The following error occurred while trying to bind the TCP/IP listener socket (10050)

CAUSE

This error message can occur if Microsoft Proxy Client is installed and enabled on Microsoft Exchange Server but Exchange Server is not connecting to the Internet through Microsoft Proxy Server.

WORKAROUND

If you are using Microsoft Proxy Server on your Exchange Server computer, you must also use Microsoft Proxy Client. Conversely, if you are using a proxy server other than Microsoft Proxy Server, you must disable Microsoft Proxy Client.
