Wsus 3.2 admin console not showing vmware machines

Hi,

I have several VM machines which are not showed in the wsus admin console. It seems that these machines have contacted with wsus because their windows update settings have the settings stablished by gpo and, the settings are disabled to changed.

Looking for a solution I have tried the following:

REG DELETE "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate" /v SusClientId /f
REG DELETE "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate" /v SusClientIdValidation /f

wuauclt /resetauthorization /detectnow

but without success.

Can anybody help me?

Thanks a lot.
