Before you deactivate a server role on a Standard Edition server or on an Enterprise Edition server in an Enterprise pool, do the following to mitigate the effects of the server role being unavailable:

Deactivating a server role can result in the loss of data and settings. Before you deactivate a server role, ensure that all data and settings have been backed up and appropriate restoration procedures are in place. For details about backing up data and server settings, see Backup and Restoration in the Operations documentation at .

If you deactivate any server role on a computer, you must deactivate all server roles that are running on the same computer. These server roles should be deactivated in the following sequence:

  1. All unified communications applications:

    • Conferencing Attendant

    • Conferencing Announcement Service

    • Response Group Service

    • Outside Voice Control

  2. Application Host

  3. Application Sharing Server

  4. A/V Conferencing Server

  5. Web Conferencing Server

  6. Web Components Server

  7. Front End Server

    You must move or delete all conference directories assigned to the pool before you can deactivate the last Front End Server in a pool.
Before you deactivate a server role, we recommend that you stop all Office Communications Server services to help ensure that no users are connected to the server. For details about stopping a service, see Starting and Stopping Services and Deactivating Server Roles.

To deactivate a server role on a Standard Edition Server or a server in an Enterprise pool

  1. Log on as a member of the RTCUniversalServerAdmins group to the Office Communications Server 2007 R2 server.

  2. Open Computer Management.

  3. Expand Services and Applications, right-click Office Communications Server 2007 R2, point to Deactivate, and then click the server role that you want to deactivate.

    Only server roles that are installed on the server and activated are available for deactivation. Additionally, the Web Conferencing Server is dependent on the Web Components Server, so the Web Components Server role is not available for deactivation until after the Web Conferencing Server role has been deactivated.
  4. In the Deactivation Wizard, review the information on each page, and then click Next.

  5. When the wizard is complete, select the View the log when you click Finishcheck box, and then click Finish.

  6. Use the log file to verify that the deactivation status in the Execution Resultcolumn (including the status of each deactivation task) for a server role is Success.

    The deactivation status that is shown in the log must indicate success before you deactivate any other server role or take other Office Communications Server actions. If any task does not complete successfully, resolve the problem and run the Deactivation Wizard again to complete the deactivation.
