Configuring Authentication by the Home Server's Domain

When users connect to a server using the Internet, they are probably in a different organization that uses a domain other than the one in which their home servers are located. To ensure that the client is authenticated by the server's domain during a remote Internet connection, the user must connect to the home server using a user account that is valid in the home server's domain. To make connecting to the home server easier, the client can be configured to prompt the user for the name and password of the user account in the home server's domain.

    To enable the client to be authenticated by the home server's domain

1. In Control Panel, double-click the Mail icon, and then select the Services tab.
2. Select Microsoft Exchange Server, and then choose Properties.
3. Select the Advanced tab.
4. From Logon network security choose None.
5. Choose OK.
