you need a default gateway. I am not familiar with windows and especially the USB connection. But you want to copy the DNS, and probably gatway settings from the server PC to the gaming PC I would think. 192.168.0.1 *might* not be correct. You can also open a command window and type

Code:
ping 192.168.0.255
This is the broadcast address your your network. Anything listening *should* respond back. That would most likely be your DNS and default gateway.


Though the server PC might be your gateway, depends on how ICS really works. I guess if one doesn't work try the other.

good luck.
