Installing the Windows EBS Messaging Server

Applies To: Windows Essential Business Server

After you finish installing the Security Server, install Windows EBS on the Messaging Server.


You must successfully finish installing the Security Server before you begin to install the Messaging Server.

Run the Messaging Server Installation Wizard

To configure the Messaging Server, the Installation Wizard uses settings that you chose during planning and while installing the Management Server.


Time to complete this task: Approximately 1.5 hours. This time may vary depending on the state of your current network and how many updates or upgrades must be applied.

To install the Messaging Server

  1. Insert Windows EBS Installation Disc 4 into the Messaging Server, and boot from the DVD. The Windows Server 2008 Installation Wizard appears.

  2. Set your locale, and then click Next.

  3. Click Install Now.

  4. When prompted, we strongly recommend that you type your 25-character product key to help avoid problems during activation. Click Next.

  5. Review the Microsoft Software License Terms. If you agree with them, select the I accept the license terms check box, and then click Next.

  6. Select Custom (advanced) as your installation type.

  7. On the Where do you want to install Windows? page, click the partition where you want to install Windows EBS, and then click Next.


    A system partition of at least 50 GB is recommended. If you need to load a driver, click Load Driver. If you need to format or partition a disk, click Drive Options (advanced). It is recommended that you format and partition the disk before you install the Messaging Server.

  8. The Installation Wizard installs Windows Server 2008.


    Your computer may restart one or more times while Windows Server 2008 is being installed.

  9. The Messaging Server Installation Wizard appears. Read the introductory information on the Welcome page, and then click Next.

  10. On the Choose the network adapter page, select the network adapter that you use to connect this server to your network. Click Next.

  11. On the Choose temporay IP addresses page, either choose to use DHCP Server to automatically assign the Messaging Server an IP address that is used during installation, or type a valid IP address that provides an Internet connection through your network. Click Next.


    These IP address settings are used temporarily during installation to download critical updates from the Microsoft Updates Web site and to connect to the computers that already exist on your network. The settings will be reconfigured to your final settings later in the installation.

  12. The Installation Wizard connects to the Microsoft Update Web site and searches for critical updates for Windows EBS. If the wizard finds any updates, it downloads and installs them. When the process is finished, on the Critical updates finished page, click Next.

  13. On the Join the Active Directory domain page, type the Active Directory domain name that the Management Server is joined to. Type the domain name and credentials of an account that has Enterprise Administrator permissions on this domain, and then click Join domain. The server restarts to join the domain. When prompted, log on with the account that you used to join the domain. The Progress of joining the domain page helps you track the progress. When you are finished joining Messaging Server to the domain, click Next.

  14. On the Check the environment page, the Installation Wizard automatically checks your environment to verify that it is compatible with Windows EBS. Read and follow the directions on the screen, and then click Check environment.

  15. On the Environment check is finished page, the Installation Wizard displays the status of the completed environment checks. When all of the checks are finished, click Next to continue.

  16. On the Set the internal network IP address page, verify that the settings that you chose during the Management Server installation are filled in as the recommended settings, and then click Next.

  17. On the Choose a volume for storing data page, you can choose to store applications data on a volume that is separate from your system volume. To do this, leave the radio button selected and click the volume that you want to use for data. If you need to format a hard disk drive, create a partition, or perform other disk-management tasks, click Disk Management. If you need to install a driver for a disk controller, see Accessing Windows Server 2008 During Windows EBS Installation.


    For better performance from Exchange Server on your Messaging Server, it is recommended that you accept the default setting and store your applications data on a separate volume from your system files.

    If you want to store your system and application data on the same volume, click Store all system and application data on the system volume.

    Click Next.

  18. Review your settings on the Review the Messaging Server installation page. To change the settings that you made since you joined the Active Directory domain, click Previous to return to previous pages. When you are finished reviewing the settings, click Install.

    The Installation Wizard installs Windows EBS on your Messaging Server and configures it with the settings that you select. The Progress of Messaging Server installation page displays progress bars that show you how the installation is proceeding. Depending on the settings that you chose, the server may restart several times.

  19. When the Messaging Server is installed, the Messaging Server installation tasks finished page appears. Click Next.

  20. If you did not choose to automatically install optional updates, the Choose optional updates page is displayed. You can choose to install the most recent updates for all of the server roles that you installed. If you prefer, you can finish the installation without downloading or installing the updates. Click Install updates to connect to the Microsoft Update Web site and install the updates, or click Finish to close the Installation Wizard without the updates.

  21. If you chose to install the updates, the Progress of optional updates page is displayed to help you track the update process.

  22. Review the status of the update installation on the Installation and updates finished page. Click Finish to close the Installation Wizard.


    If there is a problem downloading or installing an update from Microsoft Update, you can successfully finish the installation of Windows EBS without applying the update. After you finish the installation of Windows EBS on the three servers, use the update-management tools in Windows EBS to apply updates.

  23. The Continue installation page directs you to return to the Administration Console to review and begin work on the Configuration and Migration Tasks. Click Close, and then move to the Management Server.


    If you do not see the Windows desktop after you close the Installation Wizard, you can restart the computer. Or, press CTRL+ALT+DEL, and then click Start Task Manager. In Task Manager, click File, and then click New Task (Run…). In the Open text box, type explorer.exe, and then click OK.

Set the time zone on each computer

Before you start the Configuration and Migration Tasks, set the time zone on the Management Server, Security Server, and Messaging Server to the local time zone for your area.

  2. In Control Panel, double-click Date and Time.
