I am currently facing DNS_PROBE_FINISHED_NXDOMAIN status when I try to visit www.outlook.com. At first, I thought that outlook service is down for certain time. After this problem gets repeated time to time, I thought to do some research to resolve this problem.

Here is the solution for UBUNTU:
Step 1: Open terminal. Type or copy the following command:

sudo nano /etc/resolv.conf

Step 2: Add the following line:

nameserver 8.8.8.8
nameserver 8.8.4.4

Step 3: Then save and restart localhost:

sudo service network-manager restart

Now, reload the page your problem is gone. Now you can reach to you desired site.

In WINDOWS:
Step 1: Right click on internet icon on the task bar then Click on Open Network and Sharing Center.
Step 2: Click on  change adapter settings on the left side
Step 3: Choose the network in which you are connected, then right click on it and go to properties.
Step 4: In the window you wil see Internet Protocol Version 4 (TCP/IPv4). Open it and click the properties.
Step 5: Follow the instruction below.

Step 6: Restart your network but right clicking on the network in which you are connected or restart your computer.
You are connected!.
Happy reading.
