Description
Before you can install Skype for Business Server, you must make a number of forest-level changes to Active Directory Domain Services. This includes creating display specifiers and objects specific to Skype for Business Server, creating the universal security groups that are needed to manage Skype for Business Server, and granting global settings object access rights to these groups.
Forest preparation is typically carried out through the Skype for Business Server Setup Wizard. However, enterprise administrators can also perform forest preparation at any time by running the Enable-CsAdForest cmdlet.
After the Enable-CsAdForest cmdlet finishes running, you can use the Get-CsAdForest cmdlet to verify that the forest is ready for the next step in the installation process.
You must be an enterprise administrator in order to run the Enable-CsAdForest cmdlet locally.
Historical Note: This cmdlet carries out tasks similar to those carried out by the following Microsoft Office Communications Server 2007 R2 command:
Lcscmd.exe /forest /action:ForestPrep
Examples
Example 1
Enable-CsAdForest
This command prepares the Active Directory forest for the installation of Skype for Business Server. Because the GroupDomain parameter is not used, the universal security groups generated when you run the Enable-CsAdForest cmdlet will be created in the local domain.
Example 2
Enable-CsAdForest -GroupDomain northamerica.litwareinc.com
This command prepares the Active Directory forest for the installation of Skype for Business Server. The GroupDomain parameter is used to ensure that the universal security groups created by running the Enable-CsAdForest cmdlet will be created in the northamerica.litwareinc.com domain.
