I am in the process of testing workstation registration. I registered a workstation, then deleted it from ZCC and rebuilt the PC using our standard image. When I then use ZCC to re-discover and re-deploy the agent it installs but registration fails. In the log the following is logged.

[DEBUG] [1/8/2008 12:28:31 PM] [] [RegistrationManager] [] [Error during device registration: Object not found for guid: 7caa90ec9b2072c7412a7a9e4085b517. Server message: Device has previously been deleted: 7caa90ec9b2072c7412a7a9e4085b517] [] []

Do I need to delete the workstation in some other way before re-deploying the agent to the now newly re-built PC.
