Use the information in this section to troubleshoot issues with client computer groups.

Using Group Policy or registry settings to move computers into target groups is called client-side targeting. For information about how to set up client-side targeting, see the Windows Server Update Services 3.0 SP2 Deployment Guide. There are a number or reasons why computers might not appear in groups when you are using client-side targeting. Use the following information to try to resolve this problem.

By default the WSUS server is set to use server-side targeting. If you are using client-side targeting, you need to set an option on the WSUS server. For information about how to set up client-side targeting, see the Windows Server Update Services 3.0 SP2 Deployment Guide.

Make sure that the name of the target computer group matches the name of the computer group on the WSUS server. Check the Group Policy Object (GPO) or the registry setting where you enabled client-side targeting. Make sure that there are no discrepancies between the name of the computer group that is used in Group Policy and the name of the group used on the server. If WSUS cannot find a computer group on the server that is reported by a client computer, the computer will appear in the Unassigned Computers group.

If you make a change to group membership by using client-side targeting, you can reset Automatic Update with the wuauclt utility.

  1. Open a Command Prompt window.

  2. Type wuauclt.exe /resetauthorization /detectnow.

  3. Wait 10 minutes for the detection cycle to finish.
