1. Open the **/etc/sysconfig/network-scripts/ifcfg-ens192** file with the command:
   vi /etc/sysconfig/network-scripts/ifcfg-ens192
   Make sure that Primary DNS (DNS1) is the Active Directory host IP in that file. The interface name (ens192) may be different on your system, please check the correct interface configuration file accordingly.
2. Restart the network service with the command:
   systemctl restart network
3. The NTP servers should be changed. Open the chronyd config file with the command:
   vi /etc/chrony.conf
4. Edit the configurations in the config 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
