This article describes the issue when you are seeing issues where systems appear and disappear from the WSUS Console.


  • All Patch Managers versions
  • All WSUS versions


This issue occurs when imaging machines with a WU policy, it duplicates the SUSID's on the Windows Update Agent.


  1. If the machine can be found in Managed Computers, you can try to run Windows Update Agent Maintenance and Repair from the Actions Pane.
  2. Select Reset Authorization and Reset SUS Client ID, click Next and finish the task creation.


If that does not work, you can try the following which is recommended by Microsoft .

  1. On each server, browse to HKLM\Software\Microsoft\Windows\CurrentVersion\WindowsUpdate.
  2. Delete the values named PingID, SusClientID and SusClientValidation.
  3. Restart the Automatic Update service.
  4. Run the following command:
    wuauclt /resetauthorization /detectnow
