Find the COM port first (this is the device manager in Win8.1)

In my case, I had to install the drivers for usb2.0-ser. [Download Drivers at: http://www.winchiphead.com/download/CH341/CH341SER.ZIP]

1 COM port in device manager

Connect using PuTTY

[Download PuTTY at: http://www.putty.org/ ]

2 putty com3 port

Press Enter

3 terminal

If needed reboot the device (sometimes needed). Just give a power reset

4 after reboot

Enter maintainer as the username. For the password bcpb + the serial number of the firewall (letters of the serial number are in UPPERCASE format)

6 enter maintainer and password

enter exec factoryreset and press Y

7 reset or not

8 reseting

CONGRATULATIONS…!!  FortiGate Firewall is restored to the factory defaults configurations. Now you can login through preferred medium. In this case web browser is used.

How to Install System Center Configuration Manager (SCCM) 2012

line5

INTRODUCTION

System Center Configuration Manager (SCCM, also known as ConfigMgr), formerly Systems Management Server (SMS) is a systems management software product developed by Microsoft for managing large groups of computers running Windows NT, Windows Embedded, macOS (OS X), Linux or UNIX, as well as Windows Phone, Symbian, iOS and Android mobile operating systems. Configuration Manager provides remote control, patch management, software distribution, operating system deployment, network access protection and hardware and software inventory. -WIKI

Please Note That,

  • In this scenario the domain controller is running on Server 2012 R2
  • In this tutorial SQL server 2012 is installed locally (If you prefer you can do it on a remote server)
  • SQL server 2012 should be updated to cumulative update 2 or higher to install SCCM

Firstly Create the System Management Container in Active Directory Domain Services

In the Domain controller click on Server Manager –> Tools –> ADSI Edit

Getting Started with Windows PowerShell

line5

Firstly you have to Install PowerShell

As the initial step you need to make sure PowerShell is running in your system. Keep in mind that in this lab scenario Window 8.1 operating system is used. Since windows 8.1 comes with pre-installed PowerShell you can skip this step. For earlier versions such as Windows Vista you need to download and install PowerShell manually.

Download Link: https://technet.microsoft.com/en-us/scriptcenter/dd742419.aspx

To Check the PowerShell version

get-host

get-host.JPG

get-host |select-object version 

get-host version

$PSVersionTable

versiontable.JPG

Set PowerShell’s Execution Policy

  • Restricted – PowerShell won’t run any scripts. This is PowerShell’s default execution policy.
  • AllSigned – PowerShell will only run scripts that are signed with a digital signature. If you run a script signed by a publisher PowerShell hasn’t seen before, PowerShell will ask whether you trust the script’s publisher.
  • RemoteSigned – PowerShell won’t run scripts downloaded from the Internet unless they have a digital signature, but scripts not downloaded from the Internet will run without prompting. If a script has a digital signature, PowerShell will prompt you before it runs a script from a publisher it hasn’t seen before.
  • Unrestricted – PowerShell ignores digital signatures but will still prompt you before running a script downloaded from the Internet.
  • Bypass – Everything runs without a warning. Be careful with this one.
  • Undefined – No policy is defined in the current scope. This is used to allow fall-back to policies defined in lower scopes (more details below) or to the OS defaults.

Check the current policy

Get-ExecutionPolicy

01 get policy

Change the policy into RemoteSigned

Set-ExecutionPolicy RemoteSigned

02 set policy

Run Your First PowerShell script

Create a script file with following content. Name the file as MyScript.ps1

Write-Host "Hello, world"

Save the MyScript.ps1 file into following folder

C:\Scripts

03 capture

Run Following commands at PowerShell

PS C:\> Set-Location C:\Scripts

PS C:\Scripts> .\MyScript.ps1

04 run script

Alternatively you can use cmd.exe to run the scripts

In this case following script is used to get the information.

computer hostname = w

$computers = "w"

Get-WmiObject -Class win32_bios -cn $computers |

Format-table __Server, Manufacturer, Version -AutoSize

05 cmd prompt

You can use PowerShell scripts against Multiple Computers

In this scenario Windows Server 2012 R2 server domain environment is used to run the scripts.

Save following script in MyScript.ps1 file.

$computers = Get-Content -Path C:\Scripts\Computers.txt

Get-WmiObject -Class win32_bios -cn $computers -EA silentlyContinue |

Format-table __Server, Manufacturer, Version –AutoSize

Watermark Multiple Computers MyScript script file

And Make sure the computers list in the network is saved as a text file in Computers.txt.

win7
S2012

Computers list Text File.png

The path of the text file should be

C:\Scripts\Computers.txt

Run the PowerShell script

PS C:\> Set-Location C:\Scripts

PS C:\Scripts> .\MyScript.ps1

Watermark Multiple Computers powershell
