Additional instructions on changing your DNS settings in Windows Vista and in Windows 7

Some ISP’s prevent their DNS server from being able to resolve MX records. This is done intentionally, so that residential clients won’t be able to use their own SMTP server.

Additional instructions on changing your DNS settings in Windows Vista and in Windows 7

Some ISP’s prevent their DNS server from being able to resolve MX records. This is done intentionally, so that residential clients won’t be able to use their own SMTP server.

Fortunately, you can use any public DNS server. It is not mandatory to use your ISP’s DNS server. You can even combine theirs and yours, so if their DNS server will not find the right record, it will be further queried from the other DNS. We tried using some very good DNS servers from Level 3 communications. Their IP addresses are:

4.2.2.1, 4.2.2.2, 4.2.2.3, 4.2.2.4, 4.2.2.5, 4.2.2.6

You can easily set them up by going to your network settings. To do this, please follow these steps:

Instructions for Windows XP

  1. Go to your control panel, choose Network Connections and choose the connection you are using to get to the Internet
    Network Connections
  2. This window
    Local area connection status
    will open up. You can click on the “Properties” button
  3. In this window
    Local area connection properties window
    Choose “Internet Protocol” and press “Properties”
  4. In this window
    Internet Protocol (TCP/IP) properties window
    you need to choose “Advanced”
  5. Then you come to this window
    Advanced TCP/IP properties window
    where you actually add the DNS servers
