    Duplicate Device IDs overwriting Inventory records in Endpoint Manager

    adamHoward Rookie

      This article addresses how to resolve a specific issue with inventory records being overwritten due to duplicate device IDs in your environment caused by a misconfigured image or an imaging process that was done without correctly following your internal imaging process. Most likely the LANDesk agent was added to the image or was installed to a machine out of order during a new build.


      How to determine if you are having a duplicate device ID issue resulting from the imaging process already including a LANDesk agent


      Unfortunately, some of this is going to be you, your admin, or other console users saying that devices are just missing or not displaying in the network view. Noticing this issue may be occurring requires more detective work than a distinct and clear error.

      If you are seeing weird behaviors with a batch of similar machines disappearing/reappearing in Inventory, review your Core server ldscan folder


      [COREPATH]\Program Files\LANDesk\ManagementSuite\ldscan\ErrorScan


      When opening the various .scn files (.scn file extension is the OOTB default for EPM, your environment may be configured differently), you will be looking for the following information:

      Device ID ={***************************************}

      Device Name =***********

      Network - TCPIP - Host Name =************.domain


      If you see multiple files with matching device IDs but different device name/hostname then you probably have an issue with how the machine was imaged


      The reason these items are showing up in ErrorScan is because the core doesn't recognize the information even though it thinks it already has a matching device ID. Prove this by looking at the LANDesk Inventory Server warnings in the Application section of Event Viewer on the core


      Run eventvwr.msc

      Expand Windows Logs

      Click Application

      You can filter or sort by Source (this may take a few minutes)



      How to resolve duplicate device IDs overwriting inventory records caused by an image with the LANDesk agent


      NOTE: As a user with Administrative privileges on the client device


      1. STOP all LANDESK related services


      2. Delete the following Registry Keys for 32bit clients:

                HKLM\SOFTWARE\Intel\LANDesk\Common Api\UniqueID

                HKLM\SOFTWARE\LANDesk\Common Api\UniqueID


                HKLM\SOFTWARE\LANDesk\ManagementSuite\WinClient\SoftwareMonitoring\MonitorLog contents


                Delete the following Registry Keys for 64 bit clients:

                HKLM\SOFTWARE\Wow6432Node\Intel\LANDesk\Common Api\UniqueID

                HKLM\SOFTWARE\Wow6432Node\LANDesk\Common Api\UniqueID


                HKLM\SOFTWARE\Wow6432Node\LANDesk\ManagementSuite\WinClient\SoftwareMonitoring\MonitorLog contents


      3. C:\ProgramData\LANDesk (delete the entire directory and subdirectories, this is a hidden directory)


      4. Run Security Scan - look for this line "Sending current settings information to core. Failed: Core has no inventory data for this computer" (this is important to make the inventory scan work, otherwise it will fail and you will see the entry in Event Viewer)

          Without this step, I was encountering an error stating "LDISCN32: The inventory server [CORE] did not respond"


      5. Open command prompt and run C:\"Program Files (x86)"\LANDesk\LDClient\LDISCN32.EXE /V /F /SYNC

      You do not have to wait for Security Scan to finish, it will probably fail anyways until it can properly sync up with the right inventory information
