2. After you installed the DHCP
Server, you should see the role in the Server Manager. You should also see the
warning that you have to complete the DHCP Server configuration. Please click
on "More" to open the detail information.
3. In the detail window please click
on "Configure DHCP configuration" to start the Wizard.
4. The Install Wizard starts.
5. In the next step you can authorize
the DHCP server to your active directory. You should do this because DHCP will
update DNS and AD DS entry's directly after allocating IP to DHCP Client. The
credential you choose should have Domain admin rights.
6. After this the DHCP will
authorized to AD DS. In my lap this took 5 minutes.
7. Please be advised in Windows
Server 2012 "closed" don't mean the configuration has finished. It
only means that configuration will be done in Background. You can see thestatus
by clicking on the Flag in the top of the Server Manager.
8. To configure a DHCP Scope we have
to open the DHCP MMC. So please click "Tool" and than
"DHCP".
9. In the DHCP MMC we click right on
the DHCP Server and than on first on "Add/Remove Bindings..."
10. Please check if your Binding is
set on the right Network Interface if not please change it before you go on.
11. After you checked and changed the
settings please click ok and go back in the DHCP MMC. Klick right on the DHCP
IPv4 stack and select "New Scope".
12. The wizard starts. Klick
"Next".
13. Select your Scope Name and a
Description.
14. Now you have to select the IP
range and the subnet, that will be managed by your server. To calculate the
range you need you can use this online tool
15. Now you can select exclusion from
DHCP e.g. static IPs or reservations and the delay.
16. Now you have to set the lease
time. Lease means the time that a DHCP client keeps his IP before he ask the
DHCP server again for a renewal. When you have a big IP scope and enough IP's
and no special security audits in your company, you could keep 8 days. When you
use DHCP for Wi-Fi connections or only a few IP's left, you should set the
lease to maximum 2 days.
17. Here you can select if you want
to configure the DNS, default gateway and WINS via wizard or later manually. In
this guide I will configure the options with wizard. Later I will show you how
to configure it manually.
18. At first we configure the default gateway.
Normally this is a router or routable switch (Layer 3 Switch).
19. After this we configure the DNS
Options that will provided via DHCP. First the Domain name. This should be the
name of your DNS Zone that will be handled with this IPs and the DNS Servers.
You can have as much DNS Servers as you need but mostly I see that Admins have
2 or 3 redundant DNS Servers.
Every entry you make will be checked.
If an DNS Server is not reachable you will get a warning but you are able to
enter the IP either.
20. Auf configuring DNS you can
configure WINS.
21. We have nearly finished, now you
can decide if you want to start the scope now ok later. Please select now.
22. Now click "Finish" and
the scrape will be installed and activated.
23. The DHCP MMC should look now
nearly like this.
24. To check, please power on one of
your Clients in this network and check with: Ipconfig /all if you get an IP and
the settings you have entered in the DHCP Server.
