DNS server can't resolve Xbox LIVE server names

  • Level  

Okay, before getting started with these steps, there are two things to consider. First, if you’re on a wireless network, make sure you have the wireless password—you’ll need it to continue. Also, if you have manually entered your network settings, make sure you have that specific information recorded before beginning, since the first thing we’re going to do is reset the network settings to default. 

Reset network settings to default

Remove wireless adapters
If you have a wireless adapter attached to your console, turn off your Xbox 360 console, and unplug your wireless adapter from its USB port. 

Restore settings to factory default
Turn your Xbox 360 on. From your Xbox 360 dashboard (the console’s main menu), navigate to the ‘Settings’ hub, and select ‘System.’ From there, you can select ‘Network Settings,’ and the network you’re on (wired or wireless).

Once you’ve chosen the appropriate network, select ‘Configure Network.’ Navigate to the ‘Additional Settings’ tab, and select ‘Restore to Factory Defaults.’ Remember to write down any manual settings you have before doing so!

Reattach wireless adapters
If you use a wireless adapter, turn off your Xbox 360, and plug the adapter back into the console. You should be prompted to configure wireless settings. Follow the instructions onscreen to do so.

Test your LIVE connection
From the dashboard, navigate to the ‘Settings’ hub, select ‘System,’ and then ‘Network Settings.’ Select the appropriate network (wired or wireless), and then select ‘Test Xbox LIVE Connection.’

If you’re still receiving a DNS error, continue to the next step.

Restart your network equipment

Power down your console and network hardware
Turn off your Xbox 360 console, and then unplug your modem and router (or gateway). Wait 30 seconds before moving on to the next step. 

Re-activate your network hardware
Plug the modem back in, and be sure to give it at least a full minute to come back online. When it’s up to speed, do the same with your router, and repeat this step for any additional piece of network hardware you’re using. When all of your network hardware is running, turn on your console.

Run a LIVE connection test
Go to the ‘Settings’ hub on your Xbox 360 Dashboard, select the ‘System’ tile in the upper left, and then ‘Network Settings.’ Select the appropriate network (wired or wireless), and then select ‘Test Xbox LIVE Connection.’

If you still receive a DNS error, move on to the next step.

Use manual DNS settings

Obtain DNS server numbers from your PC
Press the ‘start’ button on your PC, and type cmd, and press ENTER. (if you don’t see a bar to type in, select ‘run’ and enter it there). At the prompt, type ipconfig /alland press ENTER.

Under your network name, you should see a line that begins with ‘DNS Servers.' Record this information. 

Enter DNS server numbers on your console
In the dashboard menu of your Xbox 360, go to the ‘Settings’ hub, and select the ‘System’ tile. Then, select ‘Network Settings.’ Select your network connection (wired or wireless), then select ‘Configure Network.’

On the ‘Basic Settings’ tab, select ‘DNS Settings,’ and then select ‘Manual.’ Here you will be able to select ‘Primary DNS Server’ and ‘Secondary DNS Server,’ into which you will enter the first and second numbers you recorded in the last step, respectively. When you have entered the numbers and selected ‘done’ for each one, press the (B) button and select ‘Test Xbox LIVE Connection.’ 

If you’re still encountering a DNS error, move on to the next step.

Connect directly to the modem

Try a direct modem connection
Use a network cable to connect your Xbox 360 console to your modem, bypassing the router entirely. Before running a LIVE connection test, navigate back to the dashboard, and go to the ‘Settings’ hub. Select the ‘System’ tile, then select ‘Network Settings.’ Select your network connection (wired or wireless), then select ‘Configure Network.’

On the ‘Basic Settings’ tab, select ‘DNS Settings,’ and then set it back to ‘Automatic.’ Then select ‘Test Xbox LIVE Connection.’

I’m still getting a DNS error. What do I do now?

You may want to give your Internet Service provider a call, to see if they have a resolution for the error on their end. Also, feel free to make a post in the forums, though please be sure to check the questions at the bottom of this page, to better help us help you!
