Windws Vista won't boot > tcpip.sys

Hello everyone,

This all started after I bought CS:S (game) where you have to load the server list for online gameplay.
So every time the list was loading my internet failed.
After checking the logs I figured out tcpip.sys was causing these errors.
So I did some research and found a patch which would fix this problem!
After installing I had to reboot.. and BAM the BSOD came saying that \\system32\tcpip.sys was either corrupt or missing.

I already tried Safe mode, Last known working configuration, windows vista dvd repair, all of them failed.

Please help me.

Kind regards,
Pascal
