How to enable AD recycle bin in Windows Server 2012

How to enable AD recycle bin in Windows Server 2012

Microsoft Windows Server 2008 R2 onwards allowed administrators to recover the Active Directory objects that are deleted accidentally.

Microsoft has now simplified the recovery process by incorporating Deleted Objects node in the Active Directory Administrative Center (ADAC). Graphical user interface has now been provided by the Microsoft to manage and recover the deleted objects.

Following requirements must be satisfied to use this feature:-

  • Forest functional level should be Windows Server 2008 R2
  • Recycle Bin optional-feature must be switched on
  • Objects should be recovered within Deleted Object Lifetime (DOL) – Default to 180 days.

By default, Active Directory Recycle Bin is disabled. To enable this feature, you must raise the forest functional to Windows Server 2008 R2 or higher. Once this feature has been enabled, it can’t be reverted.

Steps to use Recycle Bin User Interface in Windows Server 2012

  •  Raise the forest functional level
  •  Enable Recycle Bin
  •  Create test user, group or any OU
  •  Restore deleted objects

How to Raise the Forest Functional level:

  1. Open Active Directory Users and Computer by running dsa.msc command from powershell.
  2. Right click and select the Raise Domain functional level.
  3. Select Windows 2008 R2

A message will appear confirming functional level can’t be reversed. Click Ok to close the window.

How to Raise the functional level through Windows PowerShell:

Set-ADForestMode –Identity Arabitpro.local -ForestMode Windows2008R2Forest –Confirm:$false

How to Enable Recycle Bin feature

  1. Open Active Directory Administrative Center by running dsac.exe command from the PowerShell.
  2. Select the appropriate domain and click on the Enable Recycle Bin in the Tasks pane.
  3. A message will appear saying that Recycle Bin can’t be disabled. Click Ok. Click F5 to refresh ADAC.

Note: It may take time to replicate these changes across the domain controllers in the forest.

How to enable Recycle Bin through PowerShell:

Enable-ADOptionalFeature –Identity ‘CN=Recycle Bin Feature,CN=Optional Features,CN=Directory Service,CN=Windows NT,CN=Services,CN=Configuration,DC=ArabITPro,DC=local’ –Scope ForestOrConfigurationSet –Target ‘ ArabITPro.local’

Testing AD recycle bin by deleting and restoring deleted objects.

  • Open Active Directory Users and Computers or ADAC to create a new user, group or OU.
  • Delete the objects to restore.

Once objects are deleted, now is the time to restore it.

  • Open Active Directory Administrative Center, expand the domain and click on the Deleted Objects.
  • In the result pane, you will see objects deleted in the above steps. Select the objects which you want to restore, and click on Restore or Restore To option for restoring deleted objects to a different location.

PowerShell commands to restore the deleted objects to their original location

Get-ADObject –Filter ‘Name –Like “*Tom*”‘ –IncludeDeletedObjects | Restore-ADObject

PowerShell commands to restore the deleted objects to a different location

Get-ADObject –Filter ‘Name –Like “*Tom*”‘ –IncludeDeletedObjects | Restore-ADObject –TargetPath “OU=OU1,DC=ArabITPro,DC=local”

Once script  execution completes it will output a file called rras_vpn_users.txt in same folder as script.

Using Dsquery :

Run command prompt on a Domain Controller and then run the below command.

dsquery * -Filter “(&(objectCatgegory=person)(objectClass=user)(msNPAllowDialin=TRUE))”

 

PowerShell Get-ADUser (with AD modules):

Get-ADUser -LDAPFilter “(&(objectCategory=person)(objectClass=user)(msNPAllowDialin=TRUE))”

Installation of System Center Virtual Machine Manager 2012

Introduction

With the constant adoption of new virtualization solutions and resources by enterprises, is very important to provide a strong and powerful management solution with centralized structure where you can install, configure, monitor and manage all the available solutions in a single console. These are the concepts of System Center Virtual Machine Manager 2012(VMM2012). With it is much easier to control hosts, virtual machines, storage, network configuration and applications. With new features such as Power Management, Windows updates, creation of Private Clouds and several others that offer  a complete virtual management solution.

VMM2012 can manage the following virtual hosts:

• Hyper-V 2008 SP2, 2008 R2 Hyper-V and Hyper-V 2008 R2 SP1
• Hyper-V Server 2008 R2
• VMWare ESX / ESXi Server 3.5 and 4.1 (managed by VCenter 4.1)
• Citrix XenServer 5.6 Feature Pack 1

Note: Virtual Server and Windows 2008 (without Service Pack) are no longer supported.

New SCVMM 2012 Server Features

• VMM Server in High Availability (Cluster)
• Citrix XenServer Management
• Private Clouds creation and management encapsulating servers, network and storage arrays into a dedicated structure
• Delegating access to Private Clouds with capacity control and quotas
• Server App-V Integration and virtual applications installation to sequence through the VMM2012
• Definition of service templates for creating virtual machines, operating system images and application packages
• Automatic Host system Installation and configuration
• Creation of Hyper-V Cluster environments through administration console
• Network resources creation and configuration (ex: logical networks, IPs and MAC Pools, Load Balancers)
• Storage resources creation and configuration (ex: Arrays classifications, logical drives, storage pools)
• Physical and virtual servers update through WSUS 3.0 SP2 integration
• Power Management between hosts allowing for instance the shutdown of hosts in clusters that are not being used and the automatic start of it when necessary
• Read Only Administrator
