How to remove a role or feature in Windows Server 2012

Hi Community,

after intalling the wrong role in Windows Server 2012, I got the idea to blog how to remove the role.

1. First open the Server Manager.

2. Klick on “Manage” and than on “Remove Roles and Features”.

3. The wizzard starts.

4. Now you have to select the server were you want to remove a role.

5. Select the role you want to remove.

6. If you want to remove a feature, you can select it in this menu.

7. Now you get a small of all actions that will be performed. Klick “Remove” to start the actions.

How to Configure DHCP on Windows Server 2012

Hi Community,

today we go on with a startup/basic config for DHCP.

1. You should install the role and RSAT Management features like discribed in Point 1. to 6. in this article. Please select this time DHCP Server.

http://datacenter-flo.de/?p=332

   

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 complette 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 Wizzard.

4. The Install Wizzard 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 credetial you choose should have Domainadmin rights.

6. After this the DHCP will authorized to AD DS. In my lap this took 5 minutes.

7. Please be adviced 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 the status 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 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 wizzard starts. Klick “Next”.

13. Select your Scope Name and a Discription.

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 LINK.

15. Now you can select exclusion from DHCP e.g. static IPs or reservations and the delay.

16. Now you have to set the leasetime. 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 WiFi 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 wizzard or later manualy. In this guide I will configure the options with wizzard. Later I will show you how to configure it manualy.

18. At first we configure the default gateway. Normaly 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. In my case I will leave this point out because I have no application or operating system planned that need WINS. You can configure it manualy later at any time, so no worries.

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 scrope 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.

How to Configure DNS Reverse Lookup Zone in Windows Server 2012

Hi Community,

before we start with DHCP let us complette the DNS config by creating a Reverse Lookup Zone on our current DNS server.

1. The first thing we have to do is to open the “Server Manager” and than click “DNS” under “Tools”.

2. In the DNS MMC we click right on “Revers Loopup Zone” and select “New Zone…”.

3. Now the configuration wizzard starts. Klick “Next” to beginn.

4. Now you can select the zone type. In our case we select “Primary zone” and we want to store the information in Active Directory. So please select also “Store the zone in Active Directory”.

To learn more about DNS, feel free to visite Wiki page http://en.wikipedia.org/wiki/Domain_Name_System

5. Now we configure Zone replication. To prevent us from to much network traffic because of DNS replication, we do not replicate the zone over the complette forest, we replicate only in this domain.

6. After this you have to select the IP Version that will be handled by this zone.

7. Then enter the Network ID the musst be identified.

8. Now you have to set Dynamic Update for DNS entry’s. In a pure Windows Server DNS environment you should select “Allow only secure dynamic updates” otherwise you should select “Do not allow dynamic updates”. “Allow both nonsecure and secure dynamic updates” could be a entrace for Haks (DNS spoofing).

9. Now you get a short summary and you can create the zone by clicking “Finish”.

10. If all works fine you should see the new zone in you DNS MMC.

How to configure the first Domain Controller in a Windows Server 2012 Domain incl. DNS

Hello Community,

today I will explain how to configure the first Domain Controller in new Windows Server 2012 forest in Windows Server 2012 pure mode.

1. Open the Server Manager and klick on “Add roles and features”

2. The default page will open, click “Next”.

3. select “Role-based or feature-based installation” and click “Next”.

4. Select “Select a server from the server pool” and than select you local system. In my case FLO-SVR-DC01.

5. Now you can select the roles to install. Befor you go on with selecting roles please check if:

– you configured a static IP, Default Gateway, Subnet and DNS on the Network Interface to you client LAN

– Networkcable is connected to your switch

– you have no other Domaincontroller, DHCP- or DNS Server in your network

6. Please select for the first DC

– Active Directory Domain Services

– DNS Server

For every option Windows will ask you to install the “Remote Server Administration Tools” (RSAT). DO THIS otherwise it will be harder to finish the configuration. With later installations you can try to administrate the systems from remote or PowerShell.

7. Now the menu should look nearly like this. If this is the fact, you can click “Next”.

8. Now you have the “Feature selection”. You don’t need to install more features at the moment. Click “Next”

9. Now the Wizzard to configure ADDS starts.

10. Now you can select which operation the DC will perform. We plan to create a new forrest, so please click on “Add a new forest”.

11. Than typ in the name of your Root domain that you have planed e.g. local.company.com. After this click “Next”.

12. In the next Step you have have to select Forest function and domain level. You have to be carefull by selecting the level because some Active Directory Integrated Software e.g. some LDAP connectors, cannot work with Windows Server 2012 Domain Level. So please contact your software vendors first.

Create and set the Directory Services Restore Mode Password. Please also notice it down because you need it for a DC disaster recovery.

After this you can click next.

13. Normaly you could select in this Wizzard a DNS delegation but currently we have no DNS Server in this domain, so we have no option to delegate.

14. Now the NetBIOS Name will created. You are able to change it but you don’t have to do it.

15. After this you can set the Database folder, Log files path and SYSVOLL folder for ADDS Service. You can change the default path but I wouldn’t do this, you only force problems with this.

16. At next you get a install summary and you are able to view the PowerShell Script the will be executed (I love this option!!)

17. After this the Wizzard runs a validation check and when all is ok you can install ADDS.

18. Service installs.

19. After installation is finished you should see ADDS and DNS in your Server Manager

20. Please also look if the DNS Forward lookup Zone for your domain was created.

For this click on “Tools” in the the upper right Corner and select “DNS”.

21. Under Forward Lookup Zones you should the your Domain and there should be a NS, SOA and two A records for your DC.

22. Go back to Server Manager and select “Active Directory Users and Computers” under “Tools”

There your Domain should be listed and in “Domain Controllers” should be the “Computer Account” for your DC

23. Congratulations you installed your DC. In the next Blogs I will explain you how to install and configure DHCP and how to create a Reverse Lookup Zone in DNS.
