You can set a default Windows domain which virtual machines (VMs) created in your VMware Cloud Director organization can join. VMs can always join a domain for which they have credentials, regardless of whether you specify a default domain or not.
Starting with vSphere 8.0 Update 2, you can specify an organizational unit (OU) for your remote desktops. The OU names must be without spaces. See Create and Manage Customization Specifications for Windows and Linux in the vSphere documentation.
Prerequisites
Verify that you are logged in as an organization administrator or a role with equivalent set of rights.
