The DNS server on a domain controller is the authoritative source for resolving domain names. If the DNS server is not functioning properly, users may not be able to access resources on the network or resolve domain names.

There are a number of ways to fix a DNS server that is not functioning properly. A DNS server can be restarted, or the DNS server can be updated.

Additionally, the DNS server can be configured to use a different DNS server. If all of these methods fail, the DNS server can be replaced.
