1. Open the **/etc/sysconfig/network-scripts/ifcfg-ens160** file with the command:
   vi /etc/sysconfig/network-scripts/ifcfg-ens160
   Make sure that Primary DNS (DNS1) is the Active Directory host IP in that file.
2. Restart the network service with the command:
   systemctl restart network
3. The NTP servers should be changed. Open the **/etc/chrony.conf** file with the command:
   vi /etc/chrony.conf
4. Edit the configurations in the **/etc/ntp.conf** file according to the information below:
   server time.google.com iburst
   server time2.google.com iburst
   server time3.google.com iburst
   server time4.google.com iburst
