Description

• There are some cases where the asset tag tool is not working on the device, this article details the locations and removal of the tags if required.

Environment

• N-able N-central

Solution

• There are 3 asset tag values that needs to be deleted or removed:
  • WMI
  • Registry
  • File Value
• The NcentralAssetTool.exe is found in the following location:
  • C:\Program Files (x86)\N-able Technologies\Windows Agent\bin\NcentralAssetTool.exe
    • NOTE: If this is not on the device, please copy this over from a working device.
• To clear out the asset tags, please do the following:

  2. Run the following commands:
     • cd 'C:\Program Files (x86)\N-able Technologies\Windows Agent\bin'
