4. Confirm that you receive the feedback commands indicating that the reset was successful.
5. Close the command window.
6. Shut down the computer, and power it back on. (Cold boot the computer, do not restart it.)
7. In the Windows Control Panel, click Open Network and Sharing Center, and then click Change Adapter settings.
8. Re-enter the desired TCP/IP settings for the problem LAN connection.
