The following section provides solutions to the problems you might encounter while working with the ZENworks Agent:

Satellite menu is not displayed in the left navigation pane of the ZENworks Agent page

Source: ZENworks; ZENworks Agent.
Explanation: When you promote a device to Satellite through ZENworks Control Center, the configured Satellite role is added to the device. However, when you double-click the icon, the Satellite menu is not displayed in the left navigation pane of the ZENworks Agent page.
Action: Refresh the managed device (In the notification area of the device, right-click the icon, then click Refresh).

Unable to use rights-based authentication to remotely manage a device

Explanation: When you use rights-based authentication to remotely manage a device, the following error is logged on the device: 
Rights Authentication failed. An internal error occurred while communicating to ZENworks Management Daemon. Contact Novell Technical Services.
Possible Cause: ZENworks Agent is not installed on the device. Only Remote Management service is installed on the device.
Action: Install ZENworks Agent on the device. For more information on installing the ZENworks Agent, see in ZENworks Quick Start Reference.

Unable to launch a terminal session with a Citrix Server that has ZENworks Agent installed

Source: ZENworks; ZENworks Agent.
Explanation: After deploying the ZENworks Agent on a Citrix server, you might encounter any of the following ICA login session issues:

  • The ICA login session that is launched from Citrix agent terminates after some time.

  • The ICA login session displays the following exception:

    winlogon.exe ..Application Error

    If you try to close the exception window, the session hangs displaying the following message:

    Running login scripts
Action: Before launching a terminal session with the Citrix server, do any of the following on the server:

  • Rename NWGina.dll.

    1. In the c:\windows\system32 directory, rename NWGina.dll.

    2. In the Registry Editor, go to HKLM\Software\Microsoft\WindowsNT\CurrentVersion\Winlogon, and change the value of the CtxGinaDLL key to the new name for NWGina.dll.

    3. Reboot the server.

  • Install Novell Client.

NOTE:This needs to be done only once.

The ZENworks Agent Policies page does not display the correct status for the DLU policy

Source: ZENworks; ZENworks Agent.
Explanation: If the User Management Agent Feature is disabled or uninstalled in ZENworks Control Center (Agent Features panel on the ZENworks Agent page), the status for the DLU policy on the ZENworks Agent Policies page is displayed as Success, even though the policy is not effective on the device

The partial or the general refresh of a terminal server might cause high usage of system resources and take considerable time to refresh the server

Source: ZENworks; ZENworks Agent.
Explanation: During a partial or general refresh of a terminal server, the ZENworks agent on the server simultaneously refreshes the sessions of all the users logged into the terminal server. If too many users are logged in to the terminal server, the ZENworks agent might take substantial time to refresh the terminal server and the usage of the system resources on the server might also be high.
Action: Perform the following steps to refresh the user sessions in batches:

  1. Open the Registry Editor.

  2. Go to HKLM\Software\Novell\ZCM\.

  3. To enable batch refreshes, create a string called EnableBatchRefresh and set the value to 1.

    By default, there are 5 sessions in a batch.

  4. (Optional) To change the number of user sessions in a batch, create a string called maxUserRefreshThreads and set the desired value.

The status or collection data upload by the agent times out because of slow links or because the server is busy managing other device requests in the zone

Source: ZENworks 10 Configuration Management; ZENworks Agent.
Explanation: The agent periodically uploads the status and collection data to the Primary or Satellite Servers in the zone. On slow links or when the server is too busy managing other device requests in the zone, this attempt to upload the data might time out. To address this, the upload-timeout setting must be increased to a suitable value above the default value of 100 seconds.
Action: To change the default upload timeout value of the ZENworks Agent on a Windows managed device, perform the following steps:

  1. Open the Registry Editor.

  2. Go to HKLM\Software\Novell\ZCM\.

  3. Add the upload-timeout parameter as upload-timeout=200 seconds.

Action: To change the default upload timeout value of the ZENworks Agent on a Linux managed device, perform the following steps:

  1. Open /etc/opt/novell/zenworks/conf/xplatzmd.properties in a text editor.

  2. Add the upload-timeout parameter as upload-timeout=200 seconds.

Agents may fail to connect to the Servers on slow links

Source: ZENworks; ZENworks Agent
Explanation: On slow links, agents may fail to connect to the servers. This can be observed by the connection timeout errors in the agent log file. To address this, the connection-timeout and socket-timeout settings must be increased to a suitable value above the default value of 100000. This value is in milliseconds.
Action: To change the default values for connection-timeout and socket-timeout on a Linux or a Macintosh managed device:.

  1. Open /etc/opt/novell/zenworks/conf/xplatzmd.properties in a text editor.

  2. Add the connection-timeout parameter as connection-timeout=200000, and socket-timeout parameter as socket-timeout=200000.

An agent refresh might take a considerable amount of time because of slow links or because the server is too busy managing other device requests in the zone

Source: ZENworks Configuration Management; ZENworks Agent.
Explanation: In the debug mode, the administrator observes a read timeout error in the agent log file. To address this, the read-timeout setting must be increased to a suitable value above the default value of 30000. This value is in milliseconds.
Action: To change the default read timeout value of the ZENworks Agent on a Windows managed device, perform the following steps:

  1. Open the Registry Editor.

  2. Go to HKLM\Software\Novell\ZCM\.

  3. Add the read-timeout parameter as read-timeout=100000.

Action: To change the default read timeout value of the ZENworks Agent on a Linux managed device, perform the following steps:

  1. Open /etc/opt/novell/zenworks/conf/xplatzmd.properties in a text editor.

  2. Add the read-timeout parameter as read-timeout=100000.

By default, the general refresh on a Windows device refreshes both the device and user sessions.

Source: ZENworks; ZENworks Agent.
Explanation: The general refresh on a Windows device from the ZENworks icon or the zac command utility refreshes both the device and user sessions. You can disable the general refresh for the device session by setting the value of the ManualDeviceRefresh registry key to Disabled.
Action: To disable the general refresh for the device session, perform the following steps:

  1. Open the Registry Editor.

  2. Go to HKLM\Software\Novell\ZCM\.

  3. Set the ManualDeviceRefresh registry key value to Disabled.

The quick-task execution fails when a policy is assigned to a device.

Source: ZENworks; ZENworks Agent.
Explanation: The quick-task execution fails when a policy is assigned to a device because the primary server is unable to communicate to the Agent on the Quick Task port.
Possible Causes: The possible causes for this issue could be:

  • The Agent is switched off.

  • The Firewall of the Agent or router prevents communication with the Quick Task port.

  • Any security software, such as an antivirus, blocks the communication with the Quick Task port.

If you perform a Remote Desktop access to a Windows 2008 device and keep the console idle, the Remote Desktop connection gets disconnected after 20 seconds.

Action: Uninstallation is done by a root user. Hence, the root user’s locale needs to be set. The terminal settings, which include the user locale settings needs to be done along with the Operating System settings to support localization.

User tracking displays different values for user login name

Source: ZENworks; ZENworks Agent.
Explanation: According to the user account configuration, online Active Directory login, or cached Active Directory login, you can see the User login Id or Active Directory Full Name of the user for usage tracking.
Action: To have a consistent display of user identity, you can switch the usage tracking from Full Name mode to User-Id mode:

  1. Stop the Novell ZENworks Agent Service.

  2. In the Task Manager, terminate the TSUsage32.exe, TSUsage64.exe, and ZCMUMHelpr.exe programs.
