VMware vSphere 5.x supports Windows Server 2012 cloning and snapshot

Microsoft introduced a feature in Windows Server 2012 which enables snapshots to be reverted on Active Directory Domain Controllers without corrupting the Active Directory. This feature called VM-Generation ID also allows cloning of Active Directory running on virtual machines. VMware vSphere 5.1 does support this feature since its release but I have not read a lot of information on it. Only recently VMware wrote a blogposting titled Windows Server 2012 VM-Generation ID Support in vSphere about the support. --> Please... [Lire la suite]

Samba 4 released, brings Free alternative to Active Directory

The long wait is over — the Samba project has announced the release of an Active Directory-compatible domain controller. No longer does having an Active Directory (AD) domain controller on a network automatically mean that, somewhere in the building, a Microsoft server is lurking. Today's release announcement of Samba 4.0 means that it is now possible to control an AD domain from a non-Windows system. "Samba 4.0 comprises an LDAP directory server, Heimdal Kerberos authentication server, a secure Dynamic DNS server, and... [Lire la suite]

Au revoir Repadmin /showreps !

Suite au conseil d'un collègue, je vous propose de découvrir un outil qui permet de remplacer Repadmin en étant plus agréable à l'oeil.. il s'agit de AD Replication Status Tool. Ce logiciel permet d'avoir un visuel des réplications AD à un instant T. Relativement léger, il permettra lors d'audit ou de préventives d'avoir un rapide état des lieux de l'AD entre les différents contrôleurs de domaines.   https://www.microsoft.com/en-us/download/details.aspx?id=30005   Merci à Damien Charbonnel pour cet outil! Il faut un... [Lire la suite]

HOW TO: P2V a domain controller

A lot has been written about P2V’ing Windows Domain controllers. The preferred way is to build a new domain controller based on a virtual machine and demote the physical domain controller. Rebuilding a new domain controllers may not always be possible due to time constraints or other dependencies like additional software running on the domain controller which can not be easily migrated. However, P2V’ing of a domain controller is possible under the right conditions. These conditions are the same for any other transactional service... [Lire la suite]

Windows Server 2012 Virtualized Domain Controllers

Domain controllers are very different from non-domain controller computers on your network and that makes duplicating or cloning them somewhat problematic. Domain controllers present important security considerations and virtualizing DCs is something that must be done with care. Windows Server 2012 makes it much easier to deploy and manage secure virtualized domain controllers. In this article, we will discuss some of the issues involved. Issues and solutions One example of the issues you might encounter is when you have two domain... [Lire la suite]

Working with Domain Member Virtual Machines and Snapshots

One of the benefits of using a virtualization product that allows you to create snapshots, is the ability to create a "point in time" to which you can always revert your virtual machines. By reverting to this snapshot, you get your VM to the state in which it was saved, and are able to perform various tasks such as testing software, doing QA, creating labs and so on. However, one of the nasty issues of working with snapshots is when you have one or more virtual machines that are members of an Active Directory domain. When... [Lire la suite]

Hyper-V and Domain Controllers – Demo Tips and Tricks

In the past I have talked about the different configuration options when running Domain Controllers and Hyper-V.  One of the more interesting configurations I discussed then was having a Hyper-V server joined to a domain where the domain controller was a virtual machine running on the same instance of Hyper-V. This is actually a configuration I use all of the time when I am doing public demonstrations.  The reason why I do this is because: I do not like to ship hardware – as I have had hardware get damaged in shipping...

The fix for installation of Exchange 2007 SP2 with Windows 2008 R2 Domain Controllers is now available.

We have released the updated Setup prerequisite files for the problem we wrote about in Exchange 2007 SP2 Setup fails if all domain controllers are running Windows Server 2008 R2. This fix will unblock Exchange 2007 SP2 setup in those environments. Installation on non-Internet connected computers Using an Internet connected computer: 1. Download and extract Exchange 2007 SP2 to a local hard drive. 2. Download the updated ExBPA.PreReqs.xml and ExBPA.Readiness.xml files listed below. Please note: We suggest that you... [Lire la suite]

Meilleures pratiques Hyper-V : virtualisation des contrôleurs de domaine

Marc Bouchard de l’équipe Domaine & Sécurité a écrit un bulletin listant nos recommandations concernant la virtualisation des contrôleurs de domaine. Ce bulletin regroupe des points très importants à respecter.
