HELP ME , im getting crazy!

[A-wesker]

First of all hello.Im really getting crazy becouse im having a very annoying problem with xbox live (xbox 360).Let me tell you what the problem is.

Im connecting my Adsl modem to a Switch with an ethernet cable , from there with a cross-over cable i conect the switch to my pc in the first ethernet card.
In the second ethernet card , i use the other ethernet cable (straight) and i connect it to xbox 360.All good till here , becouse i also used Internet sharing and its ok.Also the conection of the cables is also ok.The problem is that when im running the test of 360 for XBL , it gets passes IP but it fails in DNS!!I tried so many things but nothing happens!Let me tell you my PC settings and 360 setings.

PC settings (on Xbox 360-PC network)
IP : 192.168.0.3
SubMask : 255.255.255.0
GateAway : 192.168.0.3

DNS : 192.168.0.3
DNS (2) : 192.168.0.4

ALL OF THE SETTINGS are manual.I did after i did some manual settings on 360 and i had as result IP Pass.

360 settings
IP :192.168.0.160 -> Manual
SubMask : 255.255.255.0 -> Manual
GateAway : 192.168.0.3 -> Manual

Dns : 192.168.0.3 -> Auto

So my question is what the #!#[email protected]#!$%^ i must do so as to get connected ?
Thanks for the interest.
