How to Enable DHCP on NIC Card.

Dear All,

I have Windows Server 2003 SMS and i have installed AD,DNS, & DHCP. Problem is that DHCP server not able to give IP address to Client.

On Server side everything is okay, but when i was checking ipconfig /all command in command prompt and i notice that DHCP Enable — NO.

How do i make DHCP enable Yes.
Where do i check & make it enable.

Thanks a lot in Advance.
Shri !!
