We did a new image for some devices but when we try to do remote management
on the device, we receive that error:

The managed device was unable to initialize Novell encryption scheme for the
session. Ensure that the managed device is UTC time synchronized with this
system. If the problem persists, contact Novell Technical Services

In the documentation, I found that:

Source: ZENworks 10 Configuration Management; Remote Management
Action: When the managed device is upgraded or registered, do the following:
1.Update the domain name of the new CA certificate in the registry with the
new details:
Key: HKLM\Software\Novell\ZENworks
Value: CASubject
2.Import the CA certificate of the new zone to the trusted root
3.Remove the CA certificate of the old zone from the trusted root

Is it possible to export the certificate of the server and import that
certificate with a bundle ? If yes, how can I do that and if not, how can I
do that ???
