Inventory Management - Knowledge Base

1. I cannot complete inventory scanning manually. Why?

Inventory scanning may fail with any of the following errors:

Access Denied

If you get the error message, 'Access Denied', complete the following tasks:

  • Ensure that the administrator credentials for the domain are valid and have not been changed. These credentials are specified while defining the Scope of Management (SoM).
  • Check if the DCOM settings are enabled in all the computers in your network. Refer to here for steps to enable DCOM Settings.
  • Make the following settings if the client computers are part of a workgroup (not part of a Windows Domain).
  • Turn off the Forced Guest feature
    1. Click start>Run
    2. Enter explorer
    3. Click OK
    4. Select Tools>Folder Options
    5. Click the View tab
    6. Deselect the option Use simple file sharing
    7. Click OK

RPC Server Unavailable

If you get the error message, 'RPC Server Unavailable', check if the following are switched on or enabled:

  • Remote computer: If the remote computer is not reachable, ensure that the system is switched on and running when the inventory scan is in progress.
  • Remote Administration feature: If the Remote Administration feature is disabled in the computers firewall, enable it using the steps given here.
  • File and Printer Sharing for Microsoft Networks: If the 'File and Printer Sharing for Microsoft Networks' is not enabled in the network adapter of the computers, enable this option using the steps given here.

Scanning Timed Out

If you get the error message, 'Scanning Timed Out', complete the following tasks:

  • Ensure that you have opened the following TCP ports in the Desktop Central server and added them to the exceptions list in the firewall:
    • 8020: Used for agent-server communication and to access the Web console
    • 8027: Used to complete on-demand tasks like inventory scanning, patch scanning, remote control, remote shutdown and moving agents from one remote office to another

This ensures that no data is blocked by Desktop Central when a firewall is enabled in the computer where the Desktop Central server is installed.

  • Check if the computers are switched on when inventory scanning is in progress. Ensure that the service "ManageEngine Desktop Central 7-Remote Control" is running in the computers.

    Note: This is applicable if the scanning has failed for computers in remote offices.

  • Disable virtual adapters, if any, when the computer in which the Desktop Central server is installed has multiple IP addresses. For example, a virtual adapter and two NICs.

Questions

2. I had scheduled an inventory scanning session. However, this task has failed. Why?

If scheduled inventory scanning fails, ensure that you do the following:

  • Check if the firewall running in the computer where the Desktop Central server is installed is blocking data. If the firewall is blocking data, add the following ports to its exception list:
    • 8020: Used for agent-server communication and to access the Web console
    • 8027: Used to complete on-demand tasks like inventory scanning, patch scanning, remote control, remote shutdown and moving agents from one remote office to another
  • Ensure that the local group policy (GPO) is enabled in the computers in which you want the inventory-scanning task completed. Click here for steps to enable the local GPO.

Questions

3. I have set up inventory alerts, but I do not receive any alerts?

To receive email alerts, you should configure the Mail Server settings in the Desktop Central server. For more information, see Mail Server Configurations.
