If it is necessary to reboot the domain controller, how can you ensure that everything continues to work after the reboot?

Before restarting the domain controller, it is important to ensure that:

• There is at least one additional domain controller in the network that can handle user and service requests during the restart.
• All critical services (DNS, DHCP, LDAP) are functioning correctly on other controllers.
• A backup of the domain controller's system state has been made.

After the restart, you should check:

• The status of the Active Directory service and replication between controllers using the commands dcdiag and repadmin.
• The operation of DNS records, especially SRV records needed for domain controller discovery.
• The ability of users to authenticate and access resources.

Example of a replication check:

repadmin /replsummary

If all checks are successful, the domain controller is functioning correctly after the restart.
