You must perform the following steps on each computer on which a Microsoft Lync Server 2010 server role was installed by using the Setup that is part of the Lync Server Deployment Wizard. To remove Lync Server 2010 files specific to the server role function, you run the Lync Server Deployment Wizard. The Lync Server Deployment Wizard removes Lync Server 2010 files, except for the Microsoft Lync Server 2010, Administrative Tools and Lync Server 2010, Core Components. Lync Server Deployment Wizard uses the Lync Server 2010, Core Components, so you remove the Core Components after the Lync Server Deployment Wizard has finished.

Important:
When you remove a role or change the configuration of a computer in Topology Builder, the changes must replicate to the servers in your topology. If the replication is not complete, the Lync Server Deployment Wizard may not remove the files and deactivate the server. You must confirm that replication has been successful before proceeding. You may need to run the Lync Server Deployment Wizard again to finish removing any files and to properly deactivate the server. For details, see Confirm Local Configuration Store Replication Status.
Note:
Files that are not specific to Lync Server 2010 will not be removed. These include, but are not limited to, the following:
  • Microsoft Server Speech Recognition Language files

  • Microsoft Server Speech Text to Speech Voice files

  • Microsoft SQL Server files

  • Microsoft Unified Communications API 3.0 files

  • Visual C++ 2008 Redistributable

  • Visual J# 2.0 Redistributable

  • Windows Server files such as Internet Information Server (IIS)

  • Any other files that are not specific to Lync Server 2010

For details about how to remove these files, see Remove Prerequisite Software From Lync Server.

The process of removing the installed files reverses most changes that were made during installation. Registry entries, most directories under the Program Files directory, and local users that were created during the installation are removed, which limits the amount of clean up.

To remove Lync Server 2010 files

  1. Log on to the local computer as a member of the Administrators group or Domain Admins group.

    Note:
    Log on to the computer that you want to remove from the deployment.

  6. Review the log files by clicking the arrow on the drop-down list box, clicking the log file that you want to view, and then clicking View Log.

  7. Click Finish, and then click Exit.

  8. To remove the Administrative Tools and Core Components, click Start, and then click Control Panel.

    Important:
    If replication is complete and you have run the Lync Server Deployment Wizard, Microsoft Lync Server 2010, Administrative Tools and Microsoft Lync Server 2010, Core Components are the only programs or components specific to Lync Server 2010 that you should see in Control Panel.
