W7 won't connect

[ram1009]

I'm working on a friends computer that already has W7 Ultimate installed but it won't connect to the net using my wired LAN. I ran the troubleshooter and the resultant message said W7 could not connect to the DNS server. There are several other computers on this LAN that don't have this or any problems. I hope someone can point me in the right direction.

does the computer have an IP?

I don't know. I'm pretty lost in W7.

Start -> Run/Open -> type CMD and hit Enter

at the DOS screen type ipconfig and hit Enter

There is an IP address if that's still the question. The only thing that looks out of the ordinary to me is four entries called "tunnel adapters" which all say "media disconnected". I've never heard of a tunnel adapter.

does the IP start with 169?

or 10, 172, or 196?

192.168.0.181

FYI, I have tried reinstalling the LAN driver. No difference. I also tried the e-mail program and it can't find the server either.

in CMD can you do the following:

PING 192.168,0.1
PING 192.168,0.254
PING 206.13.30.12
PING www.yahoo.com

PING 192.168,0.1
PING 192.168,0.254
PING 206.13.30.12
PING www.yahoo.com

PING 192.168,0.1 <1ms TTL64
PING 192.168,0.254 Destination Host Unreachable
PING 206.13.30.12 24ms TTL241
PING www.yahoo.com couldn't find host


I tried something else that has me thinking this box has a hardware problem. I replaced the HDD with a known good one and tried to do a fresh install of W7 Ultimate. It hung twice in the same place. Sounds like hardware to me. Maybe the MB.

can you enter the 206.13.30.12 as a DNS server IP under the network card's properties?
