Can DNS run on a non domain controller?

In a small environment, at least one domain controller (DC) should be a DNS server. It is possible to install DNS on servers which are not DCs, including non-Windows servers, but installing DNS on DCs allows the use of AD-integrated lookup zones (see below), which improve security and simplify zone replication.

Does DHCP use DNS for contacting other computers within its domain?

2 Answers. It will dish out an IP address and DNS server addresses to any computer on the same broadcast domain (ie. any contiguous network infrastructure not separated by a router). DHCP will update the computer’s name and IP in DNS, and it will replicate to all of the other DC/DNS servers in your organization.

    Are domain controllers using correct DNS settings?

    The domain controllers must be configured to use the correct DNS settings in TCP/IP property of the network card. For example, if you have four domain controllers in an Active Directory domain and if all domain controllers are running DNS server role then the settings on DNS TCP/IP property must be configured to use DNS server IP of each other domain controller in order to avoid resolution failures.
