If you were troubleshooting a computer and you couldn't get to the internet by the name, for example, www.yahoo.com, what steps would you take?

I would try to first ping it by name, by opening a command prompt in Windows. I would go to ---Start----Run---and type cmd.
When the command prompt opens I would type: ping yahoo.com
If I get replies then I would think there is some sort of name resolution problem or in other words a DNS issue.

Interviewer: OK so suppose you don't get any replies you just get time outs, now what would you do?
-Well I would then see if the network cable is plugged in, or if the wifi is turned on

Interviewer: OK so suppose the network cable is plugged into the computer, now what?
-I would check to see if there is a link light, if not I would unplug and replug the network cable. Then retest.

Interviewer: OK now suppose there is a link light now what?
-I would start thinking there might be an issue with the internet and if possible check other computers.

Interviewer: OK no one else is having the problem
-In that case I would investigate settings IP settings and check whether the user in fact has an IP address assigned, if drivers are loaded for the Network Interface Card. In fact I might just try a reboot of the computer.
-Or I might just try to release and renew the IP address. By going to Start---Run---typing in CMD, next ty ping in at the command prompt:

ipconfig/release
then
ipconfig/renew
