Absolutely. If you are running a Windows server, configure the DNS and DHCP Server settings in [Start] [Administrator Programs]. If you have a *nix server, configure the named and dhcpd daemons.
In either case, if you are running a single-server scenario, there are many advantages to running both DHCP and DNS on the same box. For example, if your local domain is set to something like "example.local", your PCs in the network would have names like accounting.example.local, server.example.local, and so on. By having both services configured together, you will be able to address your local network by the computer name ("accounting" or "ScottsDesktop", etc), without the "example.local".
If you are running Small Business Server, I think you *must* use both DNS and DHCP on that server, integrated into Active Directory.

However, one must be careful about running services on systems that may interfere with performance or be a security risk. Luckily, DHCP is a rather small service compared to others.

Describe the integration between DHCP and DNS.?
Traditionally, DNS and DHCP servers have been configured and managed one at a time. Similarly, changing authorization rights for a particular user on a group of devices has meant visiting each one and making configuration changes. DHCP integration with DNS allows the aggregation of these tasks across devices, enabling a company's network services to scale in step with the growth of network users, devices, and policies, while reducing administrative operations and costs.This integration provides practical operational efficiencies that lower total cost of ownership. Creating a DHCP network automatically creates an associated DNS zone, for example, reducing the number of tasks required of network administrators. And integration of DNS and DHCP in the same database instance provides unmatched consistency between service and management views of IP address-centric network services data.Windows Server 2003 DNS supports DHCP by means of the dynamic update of DNS zones. By integrating DHCP and DNS in a DNS deployment, you can provide your network resources with dynamic addressing information stored in DNS. To enable this integration, you can use the Windows Server 2003 DHCP service.The dynamic update standard, specified in RFC 2136: Dynamic Updates in the Domain Name System (DNS UPDATE), automatically updates DNS records. Both Windows Server 2003 and Windows 2000 support dynamic update, and both clients and DHCP servers can send dynamic updates when their IP addresses change.Dynamic update enables a DHCP server to register address (A) and pointer (PTR) resource records on behalf of a DHCP client by using DHCP Client FQDN option 81. Option 81 enables the DHCP client to provide its FQDN to the DHCP server. The DHCP client also provides instructions to the DHCP server describing how to process DNS dynamic updates on behalf of the DHCP client.The DHCP server can dynamically update DNS A and PTR records on behalf of DHCP clients that are not capable of sending option 81 to the DHCP server. You can also configure the DHCP server to discard client A and PTR records when the DHCP client lease is deleted. This reduces the time needed to manage these records manually and provides support for DHCP clients that cannot perform dynamic updates. In addition, dynamic update simplifies the setup of Active Directory by enabling domain controllers to dynamically register SRV resource records.If the DHCP server is configured to perform DNS dynamic updates, it performs one of the following actions:The DHCP server updates resource records at the request of the client. The client requests the DHCP server to update the DNS PTR record on behalf of the client, and the client registers A.The DHCP server updates DNS A and PTR records regardless of whether the client requests this action or not.By itself, dynamic update is not secure because any client can modify DNS records. To secure dynamic updates, you can use the secure dynamic update feature provided in Windows Server 2003. To delete outdated records, you can use the DNS server aging and scavenging feature.

Is it possible to install DNS active directory and DHCP on one server?
yes it is and recommended also
When configuring DHCP to use the local DNS why would you also include an ISP assigned DNS?
It is useful only in small environments. When you have only one DNS in organization and users mainly use internet (external DNS names) then you can configure in DHCP that users will obtain also external DNS server address as secon one. It will be used only when first DNS service won't be accessible. P.S.
What is the difference between dhcp server and dns?
DHCP is Dynamic Host Configuration Protocal. It assings IP addresses to the needed computers in a network dynamically. DNS is Domain Naming System(Service) It is system for naming computers and network services that is organized into a hierarchy of domains. DNS naming is used in TCP/IP networks, such as Internet, to locate computers and services through user friendly names.
Can you configure two dhcp server on a same network?
yes, one can configure two dhcp server on a same network. But for doing this, one has to define different scopes in both dhcp server in order to avoid ip address conflict. Eg. one can configure a scope for a lan with network address of 10.0.0.0 as- 10.0.0.10- 10.0.0.100 in one dhcp server. while other scope would be 10.0.0.101-10.0.0.200 . In this way we can have to dhcp servers on a same network. Which ever dhcp server receives the request for the ip address will provide the ip address. IN case for servers, one can use mac bindingin both servers so that they obtain same ip address
What can one do to resolve a dns?
One looking to resolve their DNS issues should enable reverse look-ups on their DNS server. Next, one should check for duplicate records on their DNS server. Finally, one should compare the records on their DNS server and make the necessary changes.
What is the process by which one DNS server sends a name resolution request to another DNS server?
referral
Where can one get information about configuring a DHCP server?
One can get information about configuring a DHCP server online in the following websites: Wikipedia, Microsoft or FreeBSD. One should carefully read the information, since an incorrectly configured DHCP server can mean the loss of Internet connection.
Where can one get information on a Comcast DNS server?
One can get more information on a Comcast DNS server from the following sources: What's My DNS, Comcast, DNS Knowledge, ZDNet, DSL Reports, Port Forward, Open DNS, Mac Medics, to name a few.
What are the benefits of using Windows 2003 DNS when using AD-integrated zones?
Advantages:DNS supports Dynamic registration of SRV records registered by a Active Directory server or a domain controller during promotion. With the help of SRV records client machines can find domain controllers in the network. 1. DNS supports Secure Dynamic updates. Unauthorized access is denied. 2. Exchange server needs internal DNS or AD DNS to locate Global Catalog servers. 3. Active Directory Integrated Zone. If you have more than one domain controller (recommended) you need not worry about zone replication. Active Directory replication will take care of DNS zone replication also. 4. If your network use DHCP with Active Directory then no other DHCP will be able to service client requests coming from different network. It is because DHCP server is authorized in AD and will be the only server to participate on network to provide IP Address information to client machines. 5. Moreover, you can use NT4 DNS with Service Pack 4 or later. It supports both SRV record registration and Dynamic Updates.Using Microsoft DNS gives the following benefits:If you implement networks that require secure updates.If you want to take benefit of Active Directory replication.If you want to integrate DHCP with DNS for Low-level clients to register their Host records in Zone database.
What is the process of replicating DNS information from one DNS server to another?
Zone Transfer
