Device group membership gets restored

Windows devices get registered with a registration key which adds the devices to a specific device group.
Later a ZCM administrator removes this group membership.

After some time this device group membership gets automatically restored.

Workaround:

Remove the registration key used for initial ZCM agent registration key from the file %zenworks_home%\conf\initial-web-service.

The ZCM agent has been changed to resend the registration key used for initial device registration with later registration requests so in case the device object gets lost, it can be recreate using the original used registration key (see e.g.
Device might not reuse registration key)

The server side registration servlet also reuses the registration key on already existing device objects which restores such device group membership.

The intended design is that the registration key given at initial ZCM agent registration should only be used on device creation but should not restore manually removed device group membership.
