WSUS
Clients Registered But Not Displaying Status
When a WSUS Clients
Registered and not showing any details in wsus server it may be for many reasons
like,
Wsus admin console will
display only unique client id.Each client will have a unique id when installing
an OS to it.But then we deploy a client through a same image or Ghosting each
client will share with same unique id.
In this case we need to reregister the
client with WSUS by following the steps
1.
GO to RUN and REGEDIT for registry editing
Go to path
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate
2.
Delete the following entries
PingID, SUSClientID and the AccountDomainSID values in registry
3.
Restart the "Wuauserv
Service "
a)
Net stop Wuauserv àTo stop the Service
b)
Net Start Wuauserv àTo start the Service
c)
Net Status Wuauserv àTo
check the service status
4.
Go to Command prompt(RUNàCMD) and type
a) wuauclt
/resetauthorization /detectnow
The client will start reauthenticate with
the wsus server.
