Should all domain controllers be DNS servers?
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.
Can I remove DNS from a domain controller?
Right click the domain controller you want to remove and click delete. If the DC is a global catalog server you will get an additional message to confirm the deletion. I’m going to click Yes. That is pretty much it.
What should I do if the domain controller points to itself for DNS but the SRV records still do not appear in the zone?
What should I do if the domain controller points to itself for DNS, but the SRV records still do not appear in the zone? Check for a disjointed namespace, and then run Netdiag.exe /fix. You must install Support Tools from the Windows 2000 Server or Windows Server 2003 CD-ROM to run Netdiag.exe.
Should DHCP be on domain controller?
Domain controllers do not require the DHCP Server service to operate and for higher security and server hardening, it is recommended not to install the DHCP Server role on domain controllers, but to install the DHCP Server role on member servers instead.

What is the difference between authoritative and Nonauthoritative DNS?
An authoritative answer comes from a nameserver that is considered authoritative for the domain which it’s returning a record for (one of the nameservers in the list for the domain you did a lookup on), and a non-authoritative answer comes from anywhere else (a nameserver not in the list for the domain you did a lookup …
Does Active Directory sit on a domain controller?
Active Directory is a type of domain, and a domain controller is an important server on that domain. Kind of like how there are many types of cars, and every car needs an engine to operate. Every domain has a domain controller, but not every domain is Active Directory.
How do I restrict DHCP to authenticate domain users?
DHCP is required to give out an IP before authentication can start. So you cant stop DHCP to non Domain Users. I would suggest that you look at 802.1x, This will allow you to control who can connect to your switch, this does require that the switch supports it.
What does remove DNS delegation mean?

What is DNS delegation?
Delegation. For a DNS server to answer queries about any name, it must have a direct or indirect path to every zone in the namespace. These paths are created by means of delegation. A delegation is a record in a parent zone that lists a name server that is authoritative for the zone in the next level of the hierarchy.
