Microsoft Exchange Server 2007 will reach end of support on April 11, 2017. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.

This topic explains how to configure a Domain Name System (DNS) suffix on a computer on which you will install the Microsoft Exchange Server 2007 Edge Transport server role. Before you install the Edge Transport server role, you must configure a DNS suffix for the server name. After you install the Edge Transport server role, you must not change the server name. Modification of the server name after you have installed Exchange 2007 is not supported.

The Edge Transport servers in the perimeter network and the Hub Transport servers in the Exchange organization must be able to locate each other by using host name resolution. You can accomplish this as follows:

  • Configure host records in a forward lookup zone on the internal DNS server that each server is configured to query.

  • Edit the local Hosts file for each server. The Hosts file is a local text file in the same format as the 4.3 Berkeley Software Distribution (BSD) UNIX /etc/hosts file. This file maps host names to IP addresses, and the file is stored in the \%Systemroot%\System32\Drivers\Etc folder.

Before You Begin

To perform this procedure on the Microsoft Windows server where you will install the Edge Transport server role, you must log on by using an account that is a member of the local Administrators group.

Procedure

To use Control Panel to configure the DNS suffix

  1. Click Start, click Control Panel, and then double-click System to open the System Properties.

  2. Click the Computer Name tab.

  3. Click Change.

  4. On the Computer Name Changes page, click More.

  5. In the Primary DNS suffix of this computer: field, type a DNS domain name and suffix for the Edge Transport server.
