• Try sending and receiving email.
• Third, check your LAN to make sure you can reach other computers on your LAN.
• First, check to see if you can send files across your network to another computer.
• Second, can you send and receive information from your workstation server?
• Third, are you able to print from each of your workstations on your LAN to your network printer?

If all your computers are responding on your LAN properly, however they are unable to reach the Internet, then it may be a problem with your Internet connection. In this case you should contact Internet Channel at 212.243.5200

If these steps do not work, go onto Advanced Troubleshooting

• "Pinging"
• A useful utility for trouble shooting networks is a program called ping. The ping utility transmits a packet of data to another computer on your network and records the time it takes for the packet of data to return. Ping is included in win9x and WinNT, or can be downloaded for the Macintosh. The ping utility is used to check if there is a connection between two computers. To use ping you type in the command ping followed by the IP address of the machine you are trying to reach.

• This is what you should see from a successful ping
  
  C:\ ping 216.223.200.14
  PING 216.223.200.14 with 32 bytes of data
  64 bytes from 216.223.200.14: icmp_seq=0 ttl=255 time=0.768ms
  64 bytes from 216.223.200.14: icmp_seq=1 ttl=255 time=0.715ms
  64 bytes from 216.223.200.14: icmp_seq=2 ttl=255 time=0.682 ms
  64 bytes from 216.223.200.14: icmp_seq=3 ttl=255 time=0.700ms

  4 packets transmitted, 4 packets received, 0% packet loss
  round-trip min/avg/max = 0.682/0.716/0.768 ms

• This is what you should see from an unsuccessful ping
  
  C:\ ping 206.240.56.81

• Pinging a workstation and locating IP addresses
• The first computers you should try to ping are the computers in your office. You can check the IP of a computer running win95/98 by typing winipcfg at the run line, or in WinNT you can go into the control panel, open the network icon, and then go to protocols. Open TCP/IP and it will have your IP address.
• After pinging several workstations in your office and receiving a reply from them you should try to ping Internet Channels DNS (216.223.200.14). If you do not get a reply from a workstation using ping it is most likely the IP is either not part of your network or there is a problem in your network and you should call your network consultant to find and repair the problem.
