DHCP On Windows Server 2003


DHCP

Dynamic Host Configuration Protocol

--> used to configure client TCP IP conf

How to create DHCP

--> Control panel

-->add or remove prg



--> add or remove windows components


--> network services


--> Details --> DHCP --> ok --> next --> Finish


Authorization DHCP

--> In administration tools

-->DHCP --> the red colour will appear before authorize



-->Right click on server name (ex jestel.com)

--> right Click Authorize

-->then right click and refresh

-->now red colour become green


To create scope

--> Right click on server name and click ( new scope)

--> click next



-->Type scope name

-->Click next


--> type the ip range ( ie: from starting ip to ending ip)

-->click next


-->add exclusion ( it means in the given ip which particular ips are not set to clients)

-->click next

-->next


-->next

--> type domain name & ip address

-->next

--> Finish

It becomes like the following picture

Now on client machine

--> in tcp ip properties

--> click obtain ip address automatically


--> in run à cmd

-->type ipconfig /release



--> again type ipconfig /renew

--> now system will gets ip automatically



To reserve particular ip for particular machine

--> in DHCP

--> click reservation



--> type the mac address of the particular client machines and set ip
