Connecting a computer to a Domain


Installing a domain name server (DNS) and active directory are the first step in making the work network.

I got the help for configuring the DNS and AD through videos present in my previous blog “DNS Installation & Setup”.

However I didn’t get to connect the client computer to domain that easily.

Microsoft pages guided me to use the Computer Name/Domain Changes dialog to get connected to the Domain.

But I ended up with the exception, “Network path was not found”. I found that the reason for this was that I didn’t provide the DNS server’s IP address on the client machine. By following the Step 1 below, I was able to get through it.

After completing the issues, I found that the connecting a computer to a domain is a three step process.

 

Step 1: Preparing the client to connect to the domain

1. Click on Start button, select Control Panel. Click on Network and Sharing Centre.

2. On the left pane of Network and Sharing Centre, select the Change adapter settings to open Network Connection window.

3. The Network Connection window would contain the network connections configured in the client system.

4. Right click on the Local Area Connection which is actively connected and select Properties.

5. In the network adapter Properties, select the Internet Protocol Version 4 (TCP/IPv4) and select Properties.

6. In the Internet Protocol Version 4 properties, select Use the following DNS server addresses.

7. In the Preferred DNS server, provide the IP address of the DNS server. The IP address of the DNS server can be found by executing the ipconfig /all in the server’s command prompt.

8. Select Ok twice to close the dialogs. No need for restart.

 

Step 2: Change your computer name (Optional)

Its always preferred to change the name of the computer before joining it to the Domain, because the default name of the computer may look a little odd. However this step is optional if we are comfortable with the existing name.

Follow the instructions on the Microsoft’s page, Change your computer name to do this. You would be requested to restart the computer to have the change take place.

 

Step 3: Connect the client to the Domain

1. Use the Microsoft page Connect your computer to a domain to open up Computer Name/Domain Changes dialog box.

2. In the Member of group box, select the Domain and provide the domain name. In my case 8FingerGenie.

3. On selecting Ok, it would ask for the user name and password of the domain. Use the domain server’s Administrator or equivalent credential here. I used the Administrator and its password. Before clicking Ok, ensure that the domain name you have provided is displayed under the password text box, like Domain: 8FingerGenie.

4. Once the credentials are accepted, you would be prompted with a confirmation dialog as below.

5. Clicking Ok here would display another dialog like this. This instructs us to restart the computer.

6. Once the machine is restarted, it is connected to the DNS. We can find the computer’s name added to Active Directory of the AD-DS server. In my case, the new computer’s name is Perseus and I could find that the active directory was displaying that as below.

The virtual machine could not be started because the hypervisor is not running


Hyper-V is a key feature that Windows Server 2008 R2 provides. It is provided as one of the server roles. The main component of Hyper-V is called Hypervisor. It’s the virtualization software between the hardware and the operating system to support multiple operating systems to run on the same host machine.

 

Exception

I got the following error after installing the Hyper-V role in the Windows Server 2008 R2.

Hper-V exception

 

Explanation

Though the virtualization software is provided by the Windows Server, its not the end of story. The hardware has to support it. Virtualization requires a 64 bit processor that is equipped with the virtualization (Intel VT and AMD-V) technology. Intel has a huge list of processors supporting virtualization technology and so is AMD.

By default the virtualization technology is disabled. Installation of Hyper-V also requires enabling of the virtualization technology in the hardware.

 

Solution

In my case, I have a Intel Xeon processor which supports the virtualization technology (Intel VT). The next possible solution is to enable the hardware-assisted Virtualization.

In the server startup, I pressed F2 to enter the BIOS set up. The dell machine’s Bios version was 1.6.4.

Under the Processor Settings I found the Virtualization Technology. I found it was disabled. I enabled it and saved the Bios changes.

This solved the exception in the Hyper-V. The Hyper-V then was able to connect and install another operating system on my new virtual machine.

DNS Installation & Setup


I bought a new Dell server recently. When I looked out for help in configuring DNS I found the following videos very much helpful. I write this blog just to make sure that I don’t lose these videos.

 

Following videos guides the setup of Active Directory Server

dcpromo.exe helps to install the Active Directory Services.
