Novell ZENworks 10 Configuration Management
ERROR: "[DEBUG] [30/07/2007 19:32:10]  [RegistrationManager]  [Error during device registration: Unexpected server result. Server code: -34. Server message Invalid Device Authentication Information.]  "
shown in %ZENWORKS_HOME%\logs\LocalStore\zmd-messges.log
After installing the ZCM agent on a workstation, then reverting to a snapshot taken prior to the install, when re-installing the agent, the workstation will not register.
There are three ways to fix this:
- Delete the GUID from the registry
(ZCM 10.3 onwards, HKLM\Software\Novell\ZCM\PreAgent
for previous versions, HKLM\Software\Novell\Zenworks\PreAgent
- Remove the workstation from the database.
- In ZENworks 10.2.1 and above use
zac reg -g
to create a new GUID for this device. NOTE: -g must not be used on a server or satellite device.
The problem occurs, because the workstation has registered, and ZCM expects that it will know the password it was provided with at registration time: the workstation will not know the password, because the VMWARE snapshot was from a time prior to registration. Deleting the GUID from the registry will make the workstation register as a fresh device, as will removing the device from the database.
