Windows 10 - Convert MBR to GPT

MBR2GPT.EXE is a new tool in Windows 10 that converts a disk from Master Boot Record (MBR) to GUID Partition Table (GPT) partition style without modifying or deleting data on the disk. The tool is designed to be run from a Windows Preinstallation Environment (Windows PE) command prompt, but it can also be run from the full Windows 10 OS environment. With Windows 10, version 1703, you can also convert from BIOS to UEFI during an in-place upgrade with a Configuration Manager task sequence.

Watch this short demo to get a closer look at this new tool.

GPO - How to create local Administrator account using Group policies

Veeam - Incremental vs. differential methods compare

Here it is an explanation of differential concept during Tape Era and Veeam Incremental backup against Reverse incremental backup.

More details can be found in this Veeam article.

Differential backup

The forward incremental backup with Veeam is the default to write backups on disk. With a forward incremental backup, the virtual machine’s new, unique blocks are transferred to a separate file — the .vib file — after the full backup has been taken (Sunday in the example below). This is repeated with each restore point created, indicated as daily backups in the figure below. One additional technique that is used is the synthetic full backup. This is a great way to reduce the stress on primary storage and still have a complete restore point in one file. The synthetic full backup is created by reading the full backup contained in the .vbk file and the incremental backups to create a full backup file with the contents already in the backup repository. The forward backup is shown below:



Veeam recommends the reverse incremental backup for general-purpose storage, such as holding your backups on a SAN or direct-attached storage devices. The latest restore point is always a full backup file in this example, and the incremental backups are reflected by the previous restore points. The incremental process in this example happens by copying the unique blocks of the VM and then injecting that into the full backup. The blocks that represent the previous restore point are put in a reverse incremental file .vrb that will exist for each restore point in the backup chain. The diagram below shows this process:

Powershell - Manage AD through Command line

There are several powershell command line to manage or to get Ad information.

To use these feature you need to install some modules depending on your Operative system.



1) Windows 7 
These feature is enabled on RSAT module (download Link) and then you need to enable it as follow:

After that you need to launch this command (if you are using old powershell version

Import-Module ActiveDirectory

Precedent command need to be launched everytime. If you want to have it automatically installed you need to , for your account only, add the command Import-Module ActiveDirectory to %UserProfile%\My Documents\WindowsPowerShell\profile.ps1.
If you only want to import the module in the PowerShell console, you would add the above command to Microsoft.PowerShell_profile.ps1.

REMARKS PowerShell command will work only if execution policy is set to RemoteSigned or Unrestricted.

Here it is correct command line:

Set-ExecutionPolicy RemoteSigned



2) Windows 2008 R2 Rsat is already installed and you simple need to enable it like following screenshot.




Import-Module ServerManager
Add-WindowsFeature RSAT-AD-PowerShell
Import-Module ActiveDirectory

Alternatively:


3) Windows 8/8.1 you need only to download RSAT @ 8.0 or RSA @8.1.
All options are enabled by default and nothing more is necessary.

4) Windows 2012 and 2012 R2

You can install from here 



or utilizing this command

Add-WindowsFeature RSAT-AD-PowerShell

You do not need to import module.

5) Windows 2016

Through Powershell you can launch these commands:

Get-WndowsFeature RSAT-AD-PowerShell to view if it is installed.

Install-WindowsFeature RSAT-AD-PowerShell

Then:

Import-module activedirectory

Get-Module

You will review in Administrative tools --> Active Directory Module for Active directory

6) Windows 10

you can use this script:

https://gallery.technet.microsoft.com/Install-the-Active-fd32e541

RSAT Windows 10


<---------->

You can launch this command line to verify installation went fine

Get-ADUser

You can review all powershell commands available here:

Just to take confidence about potentiality of this commands you can.

Finding Locked-Out Users

Search-ADAccount -LockedOut | where {$_.ObjectClass -eq 'user'} | FT Name,ObjectClass -A

Finding Users Whose Accounts Are About to Expire

The following example demonstrates how to find all the users whose accounts are about to expire in the next 90 days:

Search-ADAccount -AccountExpiring -TimeSpan 90.00:00:00 | where {$_.ObjectClass -eq 'user'} | FT Name,ObjectClass –A

 Get-ADUser, which enables you to query information about Active Directory user objects. 

To view number of failed logons since the last successful logon for a particular user.

Get-ADUser -Filter {Name -eq "Administrator"} -Properties * | Select-Object Name, msDS-FailedInteractiveLogonCountAtLastSuccessfulLogon

Here it is a Microsoft article that let review all commands that can be useful



Here it is an article that explain some advantages of powershell

Hacker - Wifi without password and DNS Spoofing/Arp Poisoning

Wifi without password has higher risk than usually known from non IT persons and underestimated as problem as well.

You need consider that website to IP translation is done, obviously, from DNS server and DNS Spoofing technique (with ARP poisoning) that change website name to IP association.

In this way, with Pishing technique, a website cloning is proposed to user that write on browser, for example, www.facebook.com.

So hacker can get user and password insertion and stole, in this way, user credentials.


If you like you can read this italian article that explain more verbosely concept.

Veeam Explorer for Active Directory and Group policy Object Restore procedure

Today I would like to mention Veeam Explorer for Microsoft Active Director released with Veeam Backup & Replication versions v9 and 9.5

Veeam Explorer for Microsoft Active Directory was a part of Veeam Backup & Replication v8. Its initial functionality was intended to solve the most frequent cases administrators have with Active Directory: Granular objects and containers recovery (ok, password recovery also was included, as well as AD data export in LDIFDE format)

Starting from Veeam Backup & Replication v9, you can restore Group Policy Objects, and the process is very easy.

About domain controller backup you can review this veeam article:

https://www.veeam.com/blog/backing-up-domain-controller-best-practices-for-ad-protection.html


Group policy restore follow this step by step procedure:

The actual recovery procedure is very similar to one I described before:


  • Administrator starts application-item restore for Microsoft Active Directory from the main ribbon or via the backups hive
  • Then, the administrator selects an appropriate backup point with a known valid state
  • Veeam Backup & Replication mounts that restore point to the backup server, extracting the Active Directory database and SYSVOL catalog, and automatically opens them in Veeam Explorer for Microsoft Active Directory
  • If all prerequisites are met, the administrator should be able to find the Group Policy Objects container right below the Users and Computers container
  • Then, the administrator finds a desired GPO manually or by using the search, and performs either the restore or export procedure (figure 1)

Figure 1. Veeam Explorer for Microsoft Active Directory GPO options

Hint: As an option, the administrator can compare GPO attributes with the production state and see what exactly was changed (figure 2).

Figure 2. Veeam Explorer for Microsoft Active Directory Comparing backed up GPO with production

Additional improvements to Veeam Explorer for Microsoft Active Directory

Besides that, in the same version 9, Veeam Explorer for Microsoft Active Directory added support for the recovery of:
Active Directory-integrated DNS records (DNS integrated into Active Directory and replicated as a part of Domain Services replication)
Objects in Active Directory configuration partition (Native AD partitions containing forest-wide information about existing domains and sites available services, which come per forest and are replicated to all Domain Controllers)




Additional resources:
Note: Group Policy is a Windows Server feature (since Windows Server 2000) that allows an administrator to centrally manage the working environment of users and computers, allowing common policies to be configured from one place and then distributed at ease, while also controlling what users/computers can or cannot do.
