Possible Cause: The ConsoleOne snap-ins and the site server have different ZENworks Server Management versions.
Action: Perform the following tasks:
Ensure that the ConsoleOne snap-ins and the site server are usng the same ZENworks Server Management version. The ZENworks for Servers 3.x snap-ins do not work with ZENworks 6.5 Server Management site server, and vice versa.
Install the latest ZENworks Server Management version of the snap-ins on the console and the latest version of the site server on the server and restart the processes.
Possible Cause: The site server processes are not running on the server.
Action: Restart the ZENworks Server Management processes on the server. Wait for about 5-6 minutes and launch ConsoleOne again. If the problem persists, contact Novell Support.
