When you run the ipconfig /renew command, you receive:

An error occurred while renewing interface local area connection: The system cannot find the file specified.

This error can be caused by your firewall software or by your Windows installation being damaged.

1. Make sure that a firewall is NOT enabled on your local area connection and that 3rd-party firewall software is not installed.

NOTE: See How do I enable or disable the Internet Connection Firewall (ICF) in Windows XP?

2. Open a CMD prompt.

3. Type netsh int ip reset resetlog.txt and press Enter, to reset the TCP/IP protocol.

4. Type ipconfig /renew and press Enter. If the error still occurs, perform an in-place upgrade of Windows XP.
