Vmware clones – WSUS
23 oktober 2009
When making Windows clones in ESX/vSphere, the customization option based on sysprep, doesn’t change the WSUS client ID. This means that the new virtual machine will have the same WSUS ID as the original one, and only one, the one that connects as last, will appear in the WSUS management console.
Solution:
Delete this registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\SusClientId
and reboot the new machine.
A new WSUS client ID will be created during the next reboot…
After that run the command wuauclt /resetauthorization /detectnow
After this, both machines, the original one and the clone, will appear in WSUS management console.
