One of the workstations keeps getting the error saying An error occured
because "Method not found: 'Boolean
Novell.Zenworks.Zmd.SessionManager.IsDesktopActiva ted(Int32)'.". Does
anyone have any idea what it means???

Also at zcc console, it shows the agent service is running, but the
request failed for one or more known address" at zenworks agent status.

I tried to uninstall the agent and reinstall it but it does not fix the

Can someone give any advice?

Thank you very much!
