How to Configure Additional Virtual Servers on a Back-End Server
Topic Last Modified: 2005-05-24
If you create additional virtual servers on your Exchange front-end servers, you must add similarly configured virtual servers to the back-end servers. This procedure describes how to configure additional virtual servers on a back-end server.
Before you perform the procedures in this topic, you must create the additional virtual servers on your front-end server. For more information about creating additional virtual servers on your front-end server, see Configuring Exchange Front-End Servers.
Start Exchange System Manager: Click Start, point to Programs, point to Microsoft Exchange, and then click System Manager.
In Exchange System Manager, expand Administrative Groups if administrative groups are enabled, expand Servers, and then expand the server where you want to configure the use of an e-mail address as the logon user name.
Expand Protocols, right-click HTTP, click New, and then select HTTP Virtual Server.
In the Properties dialog box, type a name for the virtual server. Give the virtual server a consistent name, such as "adatum.com (back-end)".
Under Exchange Path, click Modify, select the appropriate domain from the list (adatum.com in this case), and then click OK.
Click Advanced, and then add the appropriate host names (mail.adatum.com in this case). The address through which the client browser accesses the front-end server is forwarded by the front-end server to the back-end server, so the back-end server must be aware of every name a client might use to reach the front-end server (for example, http://mail, http://mail.adatum.com, and so on).
Note: On the back-end server, the TCP port must be 80. This is the only port used for HTTP communication between front-end and back-end servers, regardless of the port used by the client to communicate with the front-end server. You can leave the SSL port at the default setting.
