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.
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.
