How to Troubleshoot a DNS Suffix

Control the DNS suffix settings on your computer.

When you connect a computer to a local network, the computer should automatically add the network's DNS suffix to the end of its hostname. This functionality allows other network users to connect to the computer through the file sharing or remote desktop protocols. If your computer is not accepting the correct DNS suffix when connecting to a network, you can manually adjust the DNS suffix settings in Microsoft Windows.

Instructions

1. Log in to your computer with an account that has administrative privileges.

2. Open the "Start" menu and click "Control Panel."

3. Double-click the "System" icon. Go to the "Computer Name" tab at the top of the pop-up window.

4. Click the "Change" button, then click "More." Enter the correct DNS suffix in the field labeled "Primary DNS suffix of this computer." Press "OK" or "Apply" to save the settings.

5. Restart the computer to finish setting the new DNS suffix.
