What is dhcb?
No idea. Below information obtained here: http://support.microsoft.com/kb/169289 may help. DHCP (Dynamic Host Configuration Protocol) is a standard protocol defined by RFC 1541 (which is superseded by RFC 2131) that allows a server to dynamically distribute IP addressing and configuration information to clients. Normally the DHCP server provides the client with at least this basic information: • IP Address • Subnet Mask • Default Gateway Other information can be provided as well, such as Domain Name Service (DNS) server addresses and Windows Internet Name Service (WINS) server addresses. The system administrator configures the DHCP server with the options that are parsed out to the client.
What is a dhcp server?
A DHCP Server (Dynamic Host Configuration Protocol) automatically gives network devices (computer, smart phone, etc.) the configuration information required to communicate on a network. The DHCP server will assign a device an IP address, a subnet mask and a default gateway. Some DHCP servers will also provide the network device with further configuration information such as the address of a DNS (Domain Name Server). When your computer or smart phone connects to a wireless network, it has most likely recieved is configuration from a DHCP server.
How can someone find their DNS server configuration?
Someone can find their Domain Name System, or DNS, server configuration just by using their computer. Just pull up your my computer file and search for DNS.
What is DHCP scope and why it is required?
DHCP Gives four piece of information that are required in a network today. The four piece of information are IP address of computer , IP address of router , Subnet mask and IP address of name server. DHCP is a dynamic host configuration protocol and is backward compatible with BootP.

What roles do DHCP and DNS play?
DHCP is a host configuration protocol and is dynamic . DHCP is short for Dynamic host configuration protocol and is backward compatible with earlier protocols like BOOTp . DNS is domain name system that maps name to an IP address.
What is DNSDHCPserver?
You are referring to two different severs. A DNS servers and a DHCP server. A DNS server is called a Domain Name Server, it translates IP addresses into English so we can understand it. For instance a website has two names, the IP address 192.168.40.10 and that is matched up to a name in the DNS server such as www.Microsoft.com. So the DNS server gives you the name and vice versa is you wanted to find the IP address of www.Microsoft.com then there is a DNS server that will tell you its 192.168.40.10 (not real address). The DHCP or Dynamic Host Configuration Protocol, is a program that gives you your PC address, such as 192.168.43.99, it is done automatically when you log in, this way your computer has a unique identifier so someone can send you an email and it will only go to you because you have a unique number given to you by your DHCP server.
What is the effect of command copy running config tftp?
This command will copy the running configuration (located in RAM) of a Cisco device to a TFTP server. After executing the command you will be prompted for further information about the TFTP server (Server Address, file name, etc.).
What is DHCPINFORM?
DHCPInform is a DHCP message used by DHCP clients to obtain DHCP options. While PPP remote access clients do not use DHCP to obtain IP addresses for the remote access connection, Windows 2000 and Windows 98 remote access clients use the DHCPInform message to obtain DNS server IP addresses, WINS server IP addresses, and a DNS domain name. The DHCPInform message is sent after the IPCP negotiation is concluded. The DHCPInform message received by the remote access server is then forwarded to a DHCP server. The remote access server forwards DHCPInform messages only if it has been configured with the DHCP Relay Agent..
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.
How do you configure DNS in Linux operating system?
A DNS is a Domain Name Server. A domain is the name of a website, such as wiki.answers.com. Without a domain name server, you would need to know the IP address for the website. But with DNS, the name of the website is matched up automatically to the IP address.
