Domain Prep

After the forest is prepared, the final AD preparation task is to prepare the domain for Lync Server. Unlike the previous two steps, domain prep must be performed on every domain that will host either Lync servers or Lync users. The domain prep step configures the permissions required for the universal security groups created in the previous step, and must be performed by a user that is currently a member of the Domain Admins group for the domain that the tool is run against. Continuing with the Deployment Wizard, the following steps are used to prepare the domain:

1. Click Run on Step 5: Prepare Current Domain.

2. Click Next. This action will invoke the Install-CSAdDomain PowerShell command, which creates the security group access control entries required by Lync.

3. When the command has finished executing, click View Log to review the log file and ensure that no errors or warnings were generated during domain preparation.

4. When finished, click Finish to complete the procedure and return to the Deployment Wizard.

5. Verify that the changes introduced during domain prep have replicated throughout the AD forest before installing the first Lync Server into the environment.
