DHCP client is active by default when TCP/IP is bound to an adapter.
DHCP server needs to be installed and configured separately.
A DHCP (Dynamic Host Configuration Protocol) scope defines the valid pool of IP addresses that can be assigned to the network. You need to activate a DHCP scope so that the IP addresses that are issued (or leased) to the client devices will be compatible with the network configuration. If a client is issued an invalid IP address it will not be able to communicate on the network.
After installing the DHCP role, you configure a scope by giving it an IP address range, possible exclusions, and any scope options to be given out to clients. Then, you activate the scope, and you are done.
169.x.x.x is an IP address that is assigned to your PC if it cannot receive an address from a DHCP server. You usually get this IP if your PC cannot reach your DHCP server (typically your Internet modem/router/firewall) because of a network problem. Check that your PC has a link to the network.
RARP help the PC to find its MAC address in the same network from the RARP Server.RARP Serveronly providethe IP adress to the PC by remembering its MAC.DHCP works on the same way but DHCP Server provide the PC its IP address, Subnetmask, Default Gateway and DNS Server etc...So the big difference is DHCP provide more information than your RARP Server.
DHCP has to be configured by using the DHCP snap-in MMC console. This is under the Administrative Tools once DHCP has been installed. In Windows Server 2008 you add the Role, so it isn't installed via the Control Panel at all. For configuring the scope, you need to specify the address ranges to give out, any exclusions, and scope options for default gateway, etc.
Yes, you can.
You have to find the cheat code
Activate it
DHCP will request a refresh at the half-life of the lease time. So, in your case, 12 * 60 mins, or 720 minutes.
You have to install a router with a DHCP server option on. In that way the public address will be assign to the router and your PC will get a private ip address from the DHCP server.
The port 67 and port 68 are used by DHCP and the DHCP clients.
dhcp has to be authorized
