If after running ipconfig and you have an address here are the next steps.
0.) Turn off firewall while troubleshooting
1.) Ping 127.1.0.1 - this will ensure your TCP/IP stack is functioning properly.
2.) Using Ipconfig /all make a note of your IP address, your default gateway address, and the DNS server addresses.
3.) Ping your own IP address - this will verify your NIC is working.
4.) If your router has an address, Ping it.
5.) Ping your default gateway. This will verify your connectivity to your provider.
6.) For the halibut, ping your DNS server addresses.
If all of the above works, you are on the network and working properly, so far.
Since you're using Windows 200(0) (
) do this:
At a command prompt type --> nslookup
This will fireup a utility that connects to your DNS server. You'll be at a > prompt and they'll probably have it locked down so you won't be able to do much. You can type a ? to see a list of commands you can run.
Type in this >www.cisco.com
You should get back this:
This was a command telling your DNS server to lookup the name for Cisco and give you the address.
If this doesn't work, contact your provider and tell them you are having some DNS issues and tell them what you did.
If it does work - get back to us. And we'll go from there!
