Administering HTTP Virtual Servers

HTTP servers allow authenticated users to access their mailboxes and public folder data. HTTP virtual servers can also be used to publish data to be accessed by offsite users or clients and provide access for Outlook Mobile Access or Exchange ActiveSync. When Exchange is installed, a default HTTP Virtual Server is created. As an organization grows, additional HTTP Virtual Servers may be needed for fault tolerance and load balancing. Create additional HTTP servers using the following steps:

1.	In ESM, expand the administrative groups and then the administrative group you want to work with. In the left pane, navigate to the Protocols container; expand Servers, the server to work with, and then expand Protocols.
2.	In the console tree, right-click HTTP, choose New, and then select HTTP Virtual Server. In the Properties dialog box, as shown in Figure 8.3, type a descriptive name for the new HTTP server in the Name field. Figure 8.3. Using the Properties dialog box to create a new HTTP virtual server.
3.	Using the drop-down list, select an available IP address. Choose All Unassigned to allow the HTTP server to respond on all configured but unassigned IP addresses on the server. The Transmission Control Protocol port will be automatically assigned to port 80 for HTTP and port 443 for SSL.
4.	Click Advanced on the General tab. Use the Add, Remove, and Modify options to change the server's identity. To control the maximum number of simultaneous connections, select the Limit Number of Connections check box and then type in a limit.
5.	If the default timeout value of 900 seconds is too long, type a new timeout value in the Time-Out (secs) field.
6.	Determine whether the virtual server will provide access to mailboxes or public folders and then select Mailboxes for SMTP Domain or Public Folders. Click Modify to change the default settings.
7.	Click OK to create the virtual server.
