There are enough online resources available to encourage  you prepare for CCNA. I would suggest get your hands on ICND1 and ICND2 books written by Wendell Odom. These two books are very well detailed and provide you a great insight to CCNA and teach you everything you need to know to pass CCNA.

There are other resources that could be of immense help while preparing for CCNA like Chris Bryant Video Boot Camp. And Pual Browning new site

Make sure you install GNS3 on your machine. It is a unique graphical network simulator. You would need ISO images to be able to use the routers in GNS3 and you can find them online. There is one thing that no software simulator can provide, a full switch mode you would need a real cisco switch to practice some of the commands.

For this tutorial you would need at least 1GB USB stick and fast internet. The USB stick will be formatted so don’t use a USB stick with your important files or photos stored. Your current operating system should be Windows if you are using other operating systems this will not work.

To start with you would need to get a Linux distribution (they are open source) there are large number of Linux distributions available but easiest and commonly used distribution is Ubuntu the current stable version is 12.04 you can download it from their website.

Once you have the Ubuntu downloaded then you can use Universal USB installer to load the Ubuntu on to the USB. ImageOpen the Universal USB Installer in Step 1: select Ubuntu 12.04 Desktop. Step 2: click the Browse button and find the Ubuntu distribution (ubuntu-12.04.1-desktop.iso) you downloaded before. On Step 3 it is important to select the correct USB drive in the drop down (go to My Computer and see the drive letter for your USB stick). Then click Create to make the live Ubuntu USB stick. It depends on your computer specs and the USB speed on how long would it take but it should never take longer than half an hour.

Once the USB stick is ready you can either install Ubuntu into your computer or just try running your computer via the USB you just created. To start your computer with the USB your computer should have the capability to start from a bootable USB drive.

Nowadays most desktop and laptop computers have the option to allow you select the media you would like to start your computer with by pressing the F12 button on the startup screen. However, if this doesn’t work then you would need to go to the BIOS and set the boot priority.  You can start the BIOS by pressing F2 or DEL button the startup screen. Then go to the Boot Tab on the top and make the USB the first option.

If you successfully configured your computer to start with USB you should see the image below:

ImageClick Try Ubuntu to start Ubuntu without installing or changing anything in your computer. If you would like to install Ubuntu on your computer then choose install and follow the instruction here.

Run the commandline as administrator.


Type cmd on the search box, right click on the cmd icon and Run as administrator.

Then copy and paste command below:

REG ADD "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList" /v postgres /d 0 /t REG_DWORD /f

After setting up the samba make sure you add root

smbpasswd -a root

If you get the above error try this:

smbpasswd -a -m $machinename

(the machine you are trying to join to the domain)

you might get the error the group ‘machines does not exist.

addgroup machines

try again now you should be able to add the machine name and join the doamin.

Look at the /var/log/samba/log.machinename for more details of the errors you get.
