TCP/IP stack repair

P had a laptop brought to him for troubleshooting, it was not connecting to the LAN or the internet using either the ethernet port or Wifi. Suggested that he try with a Linux live CD to rule out hardware problems, and that if hardware issues were ruled out, it might be some sort of driver issue with Windows. The next day, he got back to me with the solution.

Your guess was right. Had to do a TCP/IP stack repair to resolve the connection issue.

Followed the steps given here :

TCP/IP stack repair options for use with Vista or 7.

Start - All Programs - Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults: netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults: netsh int ipv6 reset reset.log

Reboot the machine.

  1. This solved my issue. We also had to change permissions on c:\windows\system32\mpr.dll so USERS and EVERYONE had read access.
