Having DHCP service on your network will save you a lot of time, how much?
Consider this - how long does it take to configure your network properties when
you set up a new computer? Five minutes? Ten? Thirty? And who is going to keep
track of the IP addresses that have already been used on other devices? The
network Administrator! Lots of work. As a systems admin I cringe at the thought
of how much time I spent on spread sheets with IP addresses listed by the
Thousands! So here is a tool that will save so much time you may want to give it
a pay raise!
DHCP can do more than
dole out IP addresses to computers. You can configure the service to fill in all
the blanks that took you all that time when you set up the NIC!
Along with the IP the DHCP service can configure these for your NIC:
Subnet mask, Gateway, DNS, WINS,
and more!
So lets see how you would work this magic. As with any service you need to
install it and configure it. You can use Add/Remove Programs, or Configure your
server. I would suggest Configure your server,
as with the other services the Wizard will do more pre-configuration.
Once you have the service installed you need to configure it, now this will
get involved so I will set up a table with the name of the item to be configured
and a sample of what should be in the field.
First we need to set up the console. Open the console,
add your server then right click on the server,
then right click on the DHCP label then click on
Authorize.
Next you have to create the 'Scope' the
Scope is the meat of the DHCP service. Use the table to fill out the Scope.
Now the fields that you should fill in to make set up of a new computer or
adding a computer to the network a snap!

As you look at the table one thing that should be apparent what makes this so
powerful. No? Well it is the
Address Pool! All the other stuff is just
fluff, helps the computer see other devices on the network!
With the address pool starting at 10.10.10.100 and ends at 10.10.10.254 will
give you 154 IP addresses. If you need more then add them! See the help function
on how to create a Super Scope.
Note 1:
Do not end your Address Pool with
xxx.xxx.xxx.255 [255 is reserved].
Note 2: I set this
sample up with 100 static IP addresses, this
may seem like excessive but you will need static IP addresses for servers,
printers, and Dial up among other things.
