When powering on a virtual machine, have you ever come across this error message? The parent virtual disk has been modified since the child was created. Or perhaps you are unable to remove snapshots for virtual machines on one or more datastores. That one I know causes many calls into Support. There are several cases where you may encounter Snapshot issues after experiencing issues with a virtual machine. We've just updated KB 1007849 to include a video: Consolidating snapshots (1007849) The KB and video applies to ESX 4.1... [Lire la suite]

In Exchange 2010, you can provision Personal Archives for your users. A personal archive, or an archive mailbox, is an additional mailbox where users can move older messages or messages that they don’t need to access frequently but may still want to retain for a longer period. You can also apply a Retention Policy to mailboxes to have old email moved to the archive after a certain period. Moving older email out of the primary mailbox keeps it smaller and faster, although larger mailboxes aren’t a concern according to Microsoft’s... [Lire la suite]

Exchange Server 2010 Service Pack 1 requires a number of hotfixes to be installed. These are listed in Exchange 2010 Prerequisites in Exchange 2010 documentation and in the Exchange 2010 SP1 FAQ and Known Issues post on the Exchange team blog. While preparing a server for SP1, I erroneously kept trying to install the hotfixes on the Hyper-V host sytem, which has Windows 2008 R2 (instead of the VM running Windows Server 2008 SP2). Obviously, none of the hotfixes I downloaded for Windows 2008 SP2 would apply, and the hotfix installer... [Lire la suite]

Cet article est la suite du post Permissions Exchange et Groupes imbriqués - Appartenance aux groupes de distribution Dans ce précédent post , je vous partage un script qui permet de trouver l’information d’appartenance à une groupe plus facilement. Dans ce post nous allons rechercher particulièrement l’information dans le cas de groupes de sécurité. Nous allons prendre l’exemple où l’on cherche à savoir si un utilisateur doit avoir le droit d’envoyer (Send As) sur une boîte partagée. La meilleur façon d’illustrer cela est sous...

Introduction Consider a scenario where users behind ISA Server (internal network) start to receive random prompts for authentication while trying to access internet using ISA Server as proxy. The authentication prompt persists even after entering the credentials. To resolve the issue it is necessary to restart Firewall Service. Although you probably heard or read about this scenario many times, the goal of this post is to give you a compiled version of the action plan and what to look for while analyzing the data. Data...

Pour se former aux produits de la gamme Forefront, rien de mieux que de rentrer dans le vif du sujet avec une plateforme opérationnelle. J’avais déjà présenté le Business Ready Security dans un précédent billet. Une nouvelle version de cette maquette de démonstration est disponible sur le site de Microsoft.  Celle-ci comprend toujours quinze machines virtuelles prêtes à l’emploi. Cette nouvelle version inclus: La mise à niveau de UAG 2010 avec son Service Pack 1 La version finale de Forefront EndPoint... [Lire la suite]

La mise en œuvre d’environnements VDI sur plate-forme Microsoft s’appuie sur les composants Hyper-V et System Center Virtual Machine Manager comme socle de virtualisation et d’administration ainsi que Remote Desktop Services pour les fonctionnalités de présentation (accès et de déport d’affichage) et de pilotage (gestion de l’état des machines virtuelles). Pour ce qui est de RDS les fonctionnalités liées à la présentation sont prises en charge par les services RD Gateway et RD Web Access et celles de pilotages par le service RD... [Lire la suite]

The last in the series of papers I wrote in this general area has just been published and is available here. This one details the configuration you need when you want to have Outlook Anywhere use NTLM authentication when published through TMG or UAG. Why would you ever want to do this? Well, if your clients are domain joined it does avoid the Basic authentication pop up in most cases, and because it is more secure than Basic as credentials never pass over the wire (though of course with Basic they are, or certainly should be,...

A while back we published an article explaining the support constraints that surrounded deploying Exchange 2007 with multiple Outlook Web App (OWA) Virtual Directories (see here http://msexchangeteam.com/archive/2008/01/07/447828.aspx) and as this idea seems to come up more and more frequently, we wanted to do the same for Exchange 2010. Microsoft supports using multiple OWA and Exchange Control Panel (ECP) virtual directories on a single Exchange 2010 Client Access Server, each in its own website. Each virtual directory must be...

When managing an Exchange 2010 server organization in a production environment, an Exchange Administrator many times wants to keep track of things like Database Latency, Disk Space problems, search issues, user needs, and more. PowerShell was created to give us more power in our admin efforts, and many books have already been written to assist us with mastering the ins and outs of PowerShell Programming. What if I told you that you already had some examples of PowerShell programming, right on your Exchange server? And they are pretty... [Lire la suite]
