3. SETTING UP HYPER-V
You can use the steps in the following procedure to convert a Server with a GUI installation to a Minimal Server
Interface Configuration using Server Manager:
1. On the Windows Server 2012 system, open Server Manager and select add roles and features
1. Select Hyper-V as a role
3
5. 5. The installation progress window shows as a summary what you have installed
5
6. 6. once the installation is finished, close the window
CREATING A VIRTUAL SWITCH
1. Select Hyper-V manager
6
7. 2. Select virtual switch manager
3. In this exercise we will connect the switch to a private network
4. Give the switch a name. I named it "Vm1" as shown in the following figure

8. INSTALLING WINDOWS SERVER 2012 IN HYPER-V
1. Choose a drive where the virtual machine will be stored
2. Create a folder that will contain the virtual machine
8
9. 4. In the Name text box, enter a name for the virtual machine, such as DC1.
5. By default, the virtual machine data is stored on the system disk. To select a different location, select the Store The
Virtual Machine In A Different Location check box, click Browse, and then use the Select Folder dialog box to select a
save location. Click Next.
9
10. 6. On the Assign Memory page, specify the amount of memory to allocate to the virtual machine. In most cases, you
should reserve at least the minimum amount of memory recommended for the operating system you plan to install.
Click Next.
7. On the Configure Networking page, use the Connection list to select a network adapter to use. Each new virtual
machine includes a network adapter, and you can configure the adapter to use an available virtual network for
communicating with other computers. Click Next.
10
11. 8. On the Connect Virtual Hard Disk page, use the options provided to name and create a virtual hard disk for the
virtual machine. Each virtual machine requires a virtual hard disk so that you can install an operating system and
required applications. Click Next.
9. On the Installation Options page, select Install An Operating System From A Boot CD/DVD-ROM. If you have
physical distribution media, insert the distribution media, and then specify the CD/DVD drive to use. If you want to
11
12. install from an .iso image, select Image File, click Browse, and then use the Open dialog box to select the image file to
use.
10. Click Next, and then click Finish.
12
13. CREATING A DIFFERENCING DISK
1. To ensure that you create a new machine identity, you should generalize your installation.
To do that for Microsoft operating systems, that means running sysprep. IThe simple usage of the tool is to simply
type sysprep from an elevated Command Prompt or the Run dialog box and read the dialog box. Review the
Sysprep dialog box, select the appropriate options, and then run it.
2. Ensured the generalize box is marked
13
14. 3. Change the shutdown option from reboot to shutdown then press OK
Leave the virtual machine shut down/off
14
15. 4. Locate the virtual hard drive file, vhdx, and set that as read-only. To do so, right-click the actual file, clickProperties,
then select the Set the virtual hard drive (.vhdx) file as read only. This will help prevent you or someone else from
accidentally modifying it.
15
16. 5. You no longer need the parent virtual machine configuration files or folders. In Hyper-V manager, right-click the
entry for the virtual machine and then select Delete. Confirm the deletion by clicking Delete. This should remove all
the extraneous files, leaving you only with the virtual hard disk. However, you can go check the file path to ensure
the folders and .xml files were removed. Just be sure not to remove the .vhdx file, because that is the one you want.
That is your parent virtual hard disk from which you will create the differencing disks.
16
17. 6. Right-click the Hyper-V server you want to target, click New, Hard Disk. The New Virtual Hard Disk
Wizardopens.
7. If the Before You Begin page appears, review it and then click Next.
17
18. 8. Select vhdx as the disk format
9. On Choose Disk Type, select Differencing and then click Next.
18
19. 10. On Specify Name and Location, type an appropriate name. For example, APP1.vhd and then enter a specific
location where you want to store the virtual hard disk. For example, I have stored the vhdx to I:DifferenceDisk2. Then
Click Next.
19
20. 11. On Configure Disk, in Location, type or browse to the file path to the parent vhdx that you created previously
and then click Next
12. The parent disk is under the virtual hard disks folder
13. On Completing the New Virtual Hard Disk Wizard, review your selections and then click Finish.

7. While installation is in progress, you should cease the chance to configure the root password
Configuring bind
24
25. 1. Login as root and Install bind
2. Install webmin . Before installing webmin , you may do the following steps :
a. create the /etc/yum.repos.d/webmin.repo file containing :
[Webmin]
name=Webmin Distribution Neutral
#baseurl=http://download.webmin.com/download/yum
mirrorlist=http://download.webmin.com/download/yum/mirrorlist
enabled=1
b. You should also fetch and install my GPG key with which the packages are signed, with the commands :
wget http://www.webmin.com/jcameron-key.asc
rpm --import jcameron-key.asc
25
26. Use "yum update" to install updates
Configure the network settings
26
27. Disable the firewall by typing the following commands:
iptables -L
iptables -F
systemctl disable firewalld.service
To confirm if bind is running , running the following commands:
systemctl start named.service
systemctl enable named.service
systemctl status named.service shows bind is active
Configure the named.conf configuration file
27
28. Replace the IP address 127.0.0.1 with your static IP address and "localhost" with "any"
In the same configuration file, replaced the lines highlighted where it says yes with no and comment out the last line .
28
29. Edit the resolv.conf by typing the following command : gedit resolv.conf
Configure the hosts file by adding the following as shown in the image
29
30. Configure the "hostname "file by typing the following command : gedit hostname
Configure the local-host-names file
30
31. Configure the sendmail.mc file by commenting out the following line as shown in the figure
gedit /etc/mail/sendmail.mc
I did change my server ip address to 9.0.24.16 at a point
To access the webmin site, type your < IP address >: port# , example: 9.0.24.16:1000
Your username is : root
31
33. In the domain name/network field, you can put any alias. I did earlier put fedora2.net but will later on change it to
.org.
The email address was also changed to fedora2.org.
Only the mail server field is not touched
Select address to create records
33
34. I created 2 records: a www and a blank one . For the blank record, simply leave the name field empty
Select mail address to create an MX record
34
35. Set priority to 10
Edit zone options in order to transfer the zones already created
35
36. Point the zones to the class DNS : 9.0.20.3
Create a forward look up zone pointing at the class DNS
36
37. Login windows 2012 server which is your edge server then connect to the slave the server
Enter the IP address of the slave server
37
39. In the exercise, I changed the record to .org. So please ignore the following record
The DNS could not resolve the IP address because I did not configure the named.conf properly.
39
40. Earlier I had changed the IP address from 9.0.24.10 to 9.0.24.16

41. Configuring sendmail
1. In order to use Sendmail, first ensure the sendmail package is installed on your system by running, as root
In order to configure Sendmail, ensure the sendmail-cf package is installed on your system by running, as root
2. Avoid editing the sendmail.cf file directly. To make configuration changes to Sendmail, edit
the /etc/mail/sendmail.mc file, back up the original/etc/mail/sendmail.cf, and use the following alternatives to
generate a new configuration file:
o Use the included makefile in /etc/mail/ (~]# make all -C /etc/mail/) to create a
new/etc/mail/sendmail.cf configuration file.
41
42. 3. You should be able to see the file "make" created
Edit the local-host-names file
Type gedit /etc/mail/local-host-names
