Your PC may not recognize any DNS server addresses.
A DNS server is a host on the Internet that translates Internet names (such as www addresses)

Troubleshooting a TCP/IP Network Using a Ping Utility
Most TCP/IP terminal devices and firewalls contain a ping utility that sends an echo request packet
to the designated device. The device then responds with an echo reply. Troubleshooting a TCP/IP
network is made very easy by using the Ping utility in your PC or workstation.
Testing the LAN Path to Your Firewall
You can ping the firewall from your PC to verify that the LAN path to your firewall is set up
correctly.
To ping the firewall from a PC running Windows 95 or later:
1. From the Windows toolbar, click Start and select Run.
2. In the field provided, type "ping" followed by the IP address of the firewall; for example:
ping 192.168.1.1
3. Click OK. A message, similar to the following, should display:
Pinging <IP address> with 32 bytes of data
If the path is working, you will see this message:
Reply from <IP address>: bytes=32 time=NN ms TTL=xxx
If the path is not working, you will see this message:
Request timed out
If the path is not functioning correctly, you could have one of the following problems:
