Hi,
Unable to access the LAN from my system having windows 7 OS installed. Checked in Network Sharing Center > gives me error message "The dependency service or group failed to start" and does not show the LAN active networks.
Few more observations :
-------------------------------
Laptop shows wireless connections with limited access
when connected to internet with ethernet cable > internet not working
Checked eventviewer > System Logs > gives me error message "The TCP/IP Protocol Driver Service failed to start due to following error : The system cannot find the file specified."
Checked under C:\Windows\System 32\ drivers : TCPIP.sys file is present . however ipsec.sys file is missing.
Please help with next steps to resolve the issue.

Start with:
sfc /scannow
If that doesn't work go to device manager
click on view
show hidden devices
non plug and play drivers, expend that
find "tcp/ip protocol driver" right click on it and uninstall.
