You need to ensure that Computer1 is available in the Update Services console

Your network contains an Active Directory domain. The domain contains a Windows Server Update Services (WSUS) server named Server1. A Group Policy object (GPO) named GPO1 configures all computers in the domain to use Server1 for Windows Update. You add a new Windows 7 computer named Computer1 to the domain. From the Update Services console, you discover that Computer1 is not listed as a member of any computer groups.

You verify that GPO1 is applied to Computer1.
