When scanning a network using PDQ Inventory, you receive an error, "A device attached to the system is not functioning".
If running Remote Repair against the machine, you might also see the same error in "Connect to IPC$ share".
This issue can exist under the following conditions:
- The computer is not running a Windows operating system and is not listed in Active Directory.
- One of the devices on the machine is switched off or not connected properly. Examples would be a USB drive or other external drive.
- Conflicting system and/or driver files on the machine (rare).
- The drive types (USB/external and local) are not compatible (rare).
- The machine has been infected with malware (rare).
If you receive the "A device attached to the system is not functioning" and the computer is not running a Windows operating system and is not in Active Directory:
1. This is normal behavior. You can double-click the computer name (Ctrl+O) or right-click the computer name on the main console and select Open Computer to open the computer window then select Computer from the menu and select Allow Scan to disable scanning for that computer. This will allow you to edit fields for the computer.
2. If you would like some basic information about the machine to be included, add the machine into Active Directory.
