Virtual Servers/Workstations not showing up in WSUS

Issue:  Virtual servers/workstations deployed from the same image do not show up in WSUS.  You notice that in WSUS groups that the machine listing rotates machine names everytime you refresh, but never lists them separately.

Cause:  This is caused by having the same SSID when deployed.  When sysprep is not run to prepare the image, then the machine may exhibit this behavior.  Please note:  This behavior is not consistent, but for the ones that are missing, you need to do some tweaking to get this working.


  1. After your GPO is applied correctly, stop the Windows Update service.  Command prompt –> net stop wuauserv
  2. Delete the following registry keys:
    • REG DELETE “HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate” /v AccountDomainSid /f
    • REG DELETE “HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate” /v PingID /f
    • REG DELETE “HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate” /v SusClientId /f
  3. Restart the Windows Update service.  Command prompt –> net start wuauserv
  4. Run the following command for local machine to regenerate WSUS ID.  Command prompt –> wuauclt /resetauthorization /detectnow

Give it some time and check in to make sure the machine is now showing in WSUS.  This item should apply to Windows 2012 servers, although I tried this on Windows 2008 servers only.
