Check and change the DNS Resolvers your Windows Server uses

Follow

While sending out our notifications of Legacy Resolver Shutdowns following DNS Flag Day, we have had a lot of questions from non-managed customers on how to find their DNS Server settings on their servers.

Below is a step-by-step guide on how to locate your DNS Server settings on a Windows Server.

1) Right click on the network icon down near the clock in the taskbar.

2) Select Open Network and Sharing Center

 

3) From the menu on the left - select "Change Adapter Settings"

4) Select the Network Card you would like to change - eg Local Area Connection 1 - right click on the icon and select "Properties"

5) Select "Internet protocol version 4 (TCP/IP v4)" and click the "Properties" button.

6) At the bottom of the next window, you will find your DNS Servers.  These should be set to 221.121.130.3, and 221.121.134.9

7) If these two values were not set to 221.121.130.3 and 221.121.134.9, update them, and then click OK, as shown below.

8) You should be good to go now!
