Microsoft Windows - Device not functioning error when running ipconfig
The following error occurs when attempting to run ipconfig:
Windows IP Configuration An internal error occurred: A device attached to the system is not functioning. Please contact Microsoft Product Support Services for further help. Additional information: Unknown media status code.
The problem is caused by a driver for an Intel wired network adapter.
The issue is known to be in versions 8 and up of drivers for some Intel wired network adapters drivers; e.g., Intel PRO/1000 MT Mobile wired network adapter in the ThinkPad T51, including the latest driver 8.10.3.0 (20/08/2008).
The problem doesn't exist in driver versions 7 and below.
The recommended work-around is to stay with driver 7.2.17.101 (10/26/2004).
