DNS resolution issues
DNS (Domain Name Server) servers allow for transcription between an IP address and a domain name. DNS resolution issues:
- Your browser won't display webpages.
- Mail software (Outlook, Thunderbird) can't be used
- Peer to peer software are still functional (they generally work using the IP address of their servers).
To diagnose this DNS resolution problem , use the ping command:
- E.g Ping a server using its IP address (Google): ping 220.127.116.11
- If you get a message like: " Response ...", it means you are connected to the server.
- Now ping the same server using the URL: ping www.google.com
- If you get a message like: " host not found", then you have a DNS resolution problem. .
- Start > Network Connections > Show all connections.
- Go to "Local Area Connection" (or Wireless Network).
- Right-click > "Properties".
- You will find a line "Internet Protocol TCP/IP".
- Click on Properties.
- Check "Use the following DNS servers".
- Specify the DNS servers of your ISP.
Reset your Modem
You can always try to reset your modem.
- Press and hold the reset button for a couple of seconds.
- Some modems don't have a reset button. Simply remove the power cord and connect it again to reboot the modem.
