Computer Not getting to the internet

I have a computer that is getting an IP address and everything but can't get the internet. I unplugged the ethernet cord from the computer and plugged it into my notebook and it works fine. When I plugged it back into the computer that isn't working it still didn't work.

I can ping the local gateway (192.168.3.254) but I can't ping 4.2.2.2. It's almost like its not updating its routing tables....Any ideas?

P.S. I restarted the computer.
 
Both the non functional and the functional computer is setup to be DHCP. I removed the ethernet connection in network settings and readded it but still doesn't work. Another thing that makes me wonder is that the non functioning computer is getting its IP address surprisingly quickly after I reconnect the ethernet cord.
 
Strange... is the IP address assigned to the non-functional computer in the IP range of the DHCP server? Or is it something like 169.27.141.5 or something outside of the 192.168.3.x scope?
 
nope, the ip address he gets is in the same subnet.
192.168.3.40
255.255.255.0
192.168.3.254 (gateway)

All of the other computers and devices on the network work just fine. Strange, isn't it?
 
that's the first thing I thought was the DNS servers because I setup the DNS servers but I'm unable to ping 4.2.2.2 which tells me it can't be DNS
 
the dns servers are assigned by DHCP. I can't get rid of DNS servers anyways cuz it's greyed out. It's not DNS though cuz that doesn't explain why I can't ping an ip address
 
So, is there a way to test my theory which is that it has (for some odd reason) bad routing tables? Because that's my only idea how it's possible that it can only be able to see devices within the 192.168.3.x subnet.
