    La version d’évaluation de Project Server 2016 est maintenant accessible au téléchargement ici. Pour plus d’information, la documentation Technet est disponible ici. Les licences devraient être disponibles courant mai.

    A présent l’installation de Project Server est intégrée à celle de SharePoint 2016, il n’est plus nécessaire de faire une installation séparée. Néanmoins, Project reste un produit à part entière ainsi son activation nécessite une licence. J’attire votre attention sur les éléments dépréciés de cette nouvelle version par rapport à Project Server 2013 tel que le Resource Plans qui est remplacé par le Resource Engagements. Pour plus de détails, je vous invite à consulter cet article Technet.

    Vous avez des suggestions sur cette nouvelle version, partager vos idées ou voter dans le User Voice.

    Bonne journée à tous.

    Symantec recently posted a bulletin for Endpoint Protection which may affect Lync Server, Skype for Business Server, and Exchange.  The bulletin can be found here.  If you find your Lync/Skype/Exchange services are not starting after server reboot and you are running Symantec Endpoint Protection earlier than 12.1.6, be advised:


    Windows computers hang on startup after installing Symantec Endpoint Protection earlier than 12.1.6



    After you install a version of Symantec Endpoint Protection earlier than 12.1.6, Windows computers sometimes hang on startup. This issue is intermittent, and may not occur every time the computer is started.



    The Symantec Endpoint Protection Auto-Protect component does not properly release its opportunistic lock (oplock) on the VIRSCAN7.DAT file. The default location for this file is C:\ProgramData\Symantec\Symantec Endpoint Protection\12.1.4112.4156.105\Data\Definitions\VirusDefs\20150114.001\VIRSCAN7.DAT.



    This issue is fixed in Symantec Endpoint Protection 12.1 Release Update 6 (12.1.6 or 12.1 RU6). For information on obtaining the latest build of Symantec Endpoint Protection, see Download the latest version of Symantec Endpoint Protection.

    You can use one of the following workarounds until you can update to 12.1.6 or later:

    • Manually create a folder exception for Symantec Endpoint Protection Virus and Spyware Definitions on affected computers.
      Follow the instructions in the knowledge base article Excluding a file or a folder from scans to create a folder exception for the following folder:
      C:\ProgramData\Symantec\Symantec Endpoint Protection\VersionofSEP\Data\Definitions\VirusDefs
      Where VersionOfSEP is the version of SEP installed. For example, on a computer that runs version 12.1.5 (12.1 RU5), the path to this file would be:
      C:\ProgramData\Symantec\Symantec Endpoint Protection\12.1.5337.5000.105\Data\Definitions\VirusDefs
    • In the Virus and Spyware Protection policy, disable Rescan when new definitions load.
      1. In the Virus and Spyware Protection policy, under Windows Settings > Protection Technology, click Auto-Protect > Advanced > File Cache.
      2. At the bottom, uncheck Rescan when new definitions load.
    • Disable deferred scanning in Auto-Protect by following the steps in the knowledge base article How to disable deferred scanning in Auto-Protect for Symantec Endpoint Protection.

    What are different ways to schedule a Skype Meeting?

    1. Skype for Business Client.

    2. Outlook Client.

    Well, there is another way we can create/Schedule a Skype Meetings, Skype for business Web Scheduler using any web browser.

    Web Scheduler is not something that’s available by default in Skype for Business, however we can configure it to be available for Skype users.

    Configuring Web Scheduler is pretty straight forward, this blog would guide you through the configuration procedure with reference Screenshots.

    Configuring Web Scheduler Application on Skype for business Server.

    • Before configuring Web scheduler, we see below Simple URL configurations in Skype for business Infrastructure:

    Get-CsSimpleUrlConfiguration | Select-Object -ExpandProperty SimpleUrl

    • Run below commands from Skype for business Management shell to create a new simple URL Entry for web scheduler:

    $SimpleUrlEntry = New-CsSimpleUrlEntry -Url “”

    $SimpleUrl = New-CsSimpleUrl -Component “WebScheduler” -Domain “*” -SimpleUrlEntry $SimpleUrlEntry -ActiveUrl “”

    Set-CsSimpleUrlConfiguration -Identity Global -SimpleUrl @{Add=$SimpleUrl} –Verbose


    • Now we would see another simpleurl configured below:

    Get-CsSimpleUrlConfiguration | Select-Object -ExpandProperty SimpleUrl

    • Run Step 2 from Deployment Wizard on all the Front End Servers in the Skype for business Pool, which adds the components for Web Scheduler Feature.


    • After performing above actions, we would see new Virtual Directory created under Internal & External Website on Skype for business Front End Servers below:


    • If we look further, we will have few URL Rewrite modules that gets added below:



    • As per the URL Rewrite module settings, Front end Server will redirect user to Internal/External Web services along with Scheduler Virtual Directory (Https:// which provides the sign in page.

    本日、トヨタは、自動車を人々の日常生活と結びつける取り組みの一環として、データサイエンスのハブとして機能する新会社Toyota Connected (以下、TC)の設立を発表しました。自動車の運転をよりパーソナルに、より直感的に、より安全にするためにTCが作り出すあらゆるものに対応するため、マイクロソフトのAzureはコンピューティング プラットフォームとしてハイブリッドなソリューションを提供します。

    TC の社長兼CEOであるザック ヒックス (Zack Hicks) 氏は次のように述べています。


    マイクロソフト コーポレートストラテジープランニング担当 エグゼクティブ バイスプレジデント カート デルベーン (Kurt DelBene) は次のように述べています。



    TC は、人々がテクノロジに萎縮したり、スマートフォンや車内ディスプレイを前にして当惑したりすることがないようにしながら、直感的で没入型な体験を提供し、運転者の注意を削がずに安全性を強化するために、テクノロジを「人に優しく」することを目指しています。



    ヒックス氏は「将来を見据えると、トヨタ一社だけですべてを行えるわけではありません。他社も同じです。このトヨタとマイクロソフトの素晴らしい協力関係は、新たに周囲の状況を反映した没入型の革新的なドライブ エクスペリエンスの提供に欠かせないものです」と述べています。

    Most of us will have used the Quick Access Toolbar in Windows Office apps – clip_image001even if only to click the floppy disk icon to save documents, which, like many others, makes no sense to modern life. The QAT (not to be confused with other, phonetically similar terms) lets you dock commonly-used commands to be constantly available on the top corner of your favourite Office apps.

    clip_image002Click the downward arrow to the right of the QAT and you can quickly add extra commands, either chosen from a common list or by selecting pretty much any command from the gamut of menus offered in the Office application.

    clip_image004A common QAT command is the Touch/Mouse mode option that changes the spacing between menu items and the like, but there are many other useful commands that can quickly be added to the toolbar, that make it easy to do repetitive stuff or just things that are normally buried deeply in other menus. Let’s try a couple of examples.

    In Outlook, try opening a message that someone else sent you (this one would be a good start); go to the QAT and click clip_image006the down arrow to the far right side, choose More Commands… andthen select “Developer Tab” from the Choose commands option. Now, pick the Design this Form option from the list and Add to the clip_image008toolbar. Then press OK.

    Thiswill now add a new icon to the QAT, which will let you “design” whichever form you have open. In Outlook, a “form” is used to display clip_image010Items such as email messages, contacts, calendar appointments etc. The QAT is content-sensitive to different forms, so if you add it to email, it won’t show up on appointments unless you add it there too.

    In fact, adding to appointments is the best place to do it, since you can show the date and time that an appointment was created in your calendar; if you just find an appointment that you can’t remember the context of, you could quickly show the date/time you created it and that might help figure out how valid it is. If you have a meeting that someone invited you to, you’ll easily see the date/time it was sent, but if you’re the organiser, you won’t – unless you use something like Design This Form, then navigate to All Fields and choose Date/Time fields to show all the common date or time attributes of that form.

    For more context, this topic was covered some time ago on the Electric Wand blog and a previous tip, #102.

    clip_image012Another example of QAT goodness is in OneNote– if you’re routinely using OneNote for account planning or clip_image014status reporting, it’s quite handy to be able to colour cells or rows in tables to show their status, but the menu option to set the colour would need you to go into the table menu. To quickly add to the QAT for future easy access, click the down arrow / More Commands… / choose the Table Tools tab and look for Shading, then Add>> and OK.

    Whilst you’re playing with any application’s QAT, it’s worth having a look through the other commands you might want to add – like while still in OneNote, try your favourite OneTastic macros, for example.

    clip_image016On the topic of OneNote (and we’re still talking about the desktop one, not the Modern App version), there have been some updates shipped out to Office365 users that could be interesting – especially the ability to search handwriting, not just scribbled using a Surface stylus or similar, but grabbed from a photo by OfficeLens. There’s a promise of a future update that will be able to search handwriting in any picture that’s dropped into OneNote.

    This opens the door to being able to scan in old paper notebooks for easier reference/shelf space clearance, and ditch the dead tree notebooks for digital. If you’re like controversial car design Chris Bangle, you may beg to differ.

    clip_image018To check you’re on the latest version of OneNote via O365, go to the File menu, look under Office Account and the Office Updates section, and choose Update Now from under Update Options.

    Today's interview is with...

    Umer Qureshi

    Umer Qureshi's avatar 

    Umer is a Microsoft intern in in Lahore, Pakistan. He has written 9 articles.

    Example articles:


    1. Who are you, where are you, and what do you do? What are your specialty technologies?

    I am Umer Qureshi living in Lahore, Pakistan. I am 22 years old and in my last year of bachelors degree. As I am a student so I am not working in any IT Company yet but I teach computers to O-Level (Cambridge) students. I am a .Net Developer and have some knowledge about MVC, entity framework, ADO.Net, web scraping, azure etc. I am new to blogging so that’s why I do not have a huge list of blogs. Recently I did a 6-month internship in Microsoft Innovation Centre Lahore, where I got motivated to write articles and blogs.

    Photo 1. Visit to Intel Office (March'15) - CA, USA


    2. What are your big projects right now?

    I have a couple of big projects which I am trying to complete in parallel, first of all I want to complete my degree this spring and to secure a good Job so I am getting myself prepared for the interviews and polishing my skills, secondly I want to be a MCSD (Web Applications) so preparing for that too and the third one in the list is to do my master’s degree from abroad so I can get a different exposure and learn new things.

    3. What is TechNet Wiki for? Who is it for?

    TechNet wiki is a guide to IT people from where they can seek help, and can help others. It’s a kind of digital library giving you all the things you need. I think TechNet wiki is for everyone not specifically for IT people or people working only on Microsoft technologies. TechNet wiki is so vast that everyone can be benefited somehow.

    Photo 2. Visit to Stanford University (March'15) - USA

    4. What do you do with TechNet Wiki, and how does that fit into the rest of your job?

    TechNet wiki is like a technical encyclopedia for me, whenever I need help while doing my projects or I am stuck somewhere in coding, TechNet Wiki is the first resource I seek Help from. It has helped me in doing many of my university projects, so I am very thankful to TechNet wiki and its authors. Now as I have gained at least enough knowledge to guide someone so instead of always getting help I decided to provide help by sharing my knowledge with others.

    5. What is it about TechNet Wiki that interests you?

    TechNet Wiki has a collection of great articles and authors which interests me. As I am a Microsoft lover and work on their technologies so TechNet Wiki is the most reliable source from where I like to seek help. TechNet wiki has provided a great platform to experts so they can help newbies like me. Everyone is learning by exchanging their knowledge with others.

    Photo 3. Teaching students how to code, as a volunteer in Hour Of Code (H.O.C. Dec'15) - Lahore, Pakistan.

    6. In what other sites and communities do you contribute your technical knowledge?

    I have my personal blog where I share my knowledge and also on few other platforms like code-project, c#corner and code.msdn. I share my source code on GitHub so I can provide maximum guidance to my readers with helping code for a jumpstart.

    7 .Do you have any tips for new Wiki authors?

    I am a new wiki author but as far as I have learnt is that one should try to write in a descriptive and easy way so people from different regions, speaking different languages and having little knowledge may also be able to understand what you are trying to explain. Before publishing anything perform it by yourself thinking like you are yourself a newbie and try to explain all the hurdles one can face, secondly do proof read it. 



    Thank you, Umer for all your contributions!

    Everyone, please join me in thanking Umer for his articles!

    Hello and welcome everybody to our TNWiki Article Spotlight on Tuesday.

    IoT has been around the news for a while now. In Germany we even have our own term for it ("Industrie 4.0"). Especially predictive maintenance is a common use case. Predictive maintenance tries to get the time in the future where a part can fail, for example a part of a robot in an industry plant. With Azure Microsoft offers some components which are very useful in IoT solutions. We have Stream Analytics, we have an Event Hub and we have Azure ML ... and we also have the IoT Hub. Putting them together takes some time and patience. What if you want a complete solution which has most of it already put together? That is the point where the Azure IoT Suite appears on the stage. The Azure IoT Suite contains pre-packaged solutions for common scenarios. Currently these solutions are for remote monitoring, that means monitoring multiple devices in several remote locations, and ... predictive maintenance. This solutions has a lot under the covers, such as WebJobs and Azure ML and it comes with a nice web interface. But going through it and trying to modify the solution can be hard. Luckily Peter a.k.a XAML guy wrote an article which explains the predictive maintenance solution. He shows the different components and what role they play and how you can create the solution. He also explains a little bit how the solution can be modified.

    If you want to get your feet a little bit wet and don't have the time to built a complete solution yourself Azure IoT Suite is a good starting point. To get started with the predictive maintenance part of it you should definitely check out this article.

    Je me propose de vous faire découvrir une « stack storage » typique que l’on retrouve coté serveur. Il y a des différences notables par rapport aux « stacks storage » coté poste client en raison de la complexité de certaines technologies inhérentes au monde serveur. A savoir : le multi-pathing, le fait que l’on va travailler sur des LUNs (du FC, du iSCSI, du SCSI locale) etc… L’idée étant de comprendre le cheminement que va prendre une IO pour atteindre un disque. i.e. quels devices\drivers vont prendre part à la résolution d’une IO.

     Attention, ça pique un peu. Bonne lecture !


    Le dump que nous allons analyser a été généré sur un Windows 2016 (TP3) avec une topologie représentative (mais non exhaustive) de ce que l’on peut rencontrer.

    1: kd> vertarget

    Windows 10 Kernel Version 10514 MP (4 procs) Free x64

    Pour connaitre le nombre de volumes que Windows « voit », il faut simplement rechercher les DEVICE_OBJECT gérés par le driver volmgr.sys. Dans notre cas, nous avons 4 devices:


    1: kd> !drvobj \driver\volmgr

    Driver object (ffffe000abe2cc00) is for:


    Driver Extension List: (id , addr)

        Device Object list:

    ffffe000adb4bac0 ffffe000ac832c90  ffffe000ac835980  ffffe000ac3d5580



    Il faut savoir que pour le driver volmgr.sys (comme pour certains autres), il y a toujours un device servant à « gérer » les autres devices. i.e. il y a un device qui ne représente pas un volume réel. Concernant volmgr.sys, il s’appelle toujours VolMgrControlet, est le premier device créé (donc le dernier dans la liste ci-dessus):

    1: kd> !devobj ffffe000ac3d5580

    Device object (ffffe000ac3d5580) is for:

    VolMgrControl \Driver\volmgr DriverObject ffffe000abe2cc00

    Current Irp 00000000 RefCount 0 Type 00000012 Flags 00000840

    Device queue is not busy.



    Nous savons donc que Windows, au moment de la génération du dump, « voyait » 3 volumes => HarddiskVolume 1 à 3. Les voici :


    1: kd> !devobj ffffe000adb4bac0

    Device object (ffffe000adb4bac0) is for:

    Sur ces 3 volumes, il y en 2 qui correspondent : au volume de 300MB pour la base BCD et au volume Système de Windows (typiquement, ce que nous retrouverons sur un poste client). Ce sont respectivement les 2 premiers devices créés durant la phase de boot. Nous pouvons d’ailleurs retrouver notre volume système facilement avec cette commande :


    1: kd> !driveinfo c:

    Drive c:, DriveObject ffffc000230ea8d0

        Directory Object: ffffc00022e1e630  Name: C:

           Target String is '\Device\HarddiskVolume2'

            Drive Letter Index is 3 (C:)

        Volume DevObj: ffffe000ac832c90

        Vpb: ffffe000ac83a5c0  DeviceObject: ffffe000abe18030

        FileSystem: \FileSystem\Ntfs

        Volume has 0x1703f4e (free) / 0x1bd32ff (total) clusters of size 0x1000

        94271.3 of 113971 MB free

    Nous pouvons également retrouver le nom des volumes (s’il y en a un) avec la commande !vpb (Volume Parameter Block ).

    Pour le HarddiskVolume1 (BCD), nous avons « System Reserved »:


    1: kd> !vpb ffffe000ac8358c0

    Vpb at 0xffffe000ac8358c0

    Flags: 0x1 mounted

    DeviceObject: 0xffffe000acfc2030

    RealDevice:   0xffffe000ac835980

    RefCount: 20

    Volume Label:                System Reserved



    Pour le HarddiskVolume2 (C:), nous n’avons pas de nom (car pas de label):


    1: kd> !vpb ffffe000ac83a5c0 

    Vpb at 0xffffe000ac83a5c0

    Flags: 0x1 mounted

    DeviceObject: 0xffffe000abe18030

    RealDevice:   0xffffe000ac832c90

    RefCount: 1867

    Volume Label:



    Pour le HarddiskVolume3 (une LUN), nous avons « LU-08 »:


    1: kd> !vpb ffffe000adb3efa0

    Vpb at 0xffffe000adb3efa0

    Flags: 0x1 mounted

    DeviceObject: 0xffffe000adb30030

    RealDevice:   0xffffe000adb4bac0

    RefCount: 22

    Volume Label:      LU-08



    Ce que nous avons découvert correspond pour le moment à ça :

    L’idée de cet article consistant à montrer une stack storage « serveur », nous allons maintenant rentrer dans les détails de notre LUN (LU-08) qui se trouve être notre volume HarddiskVolume3. Une stack storage est, en réalité, composée de plusieurs sous stacks différentes. Dans cet exemple, et pour illustrer un cas complexe réel, nous rencontrerons une stack File System, une stack Volume, une stack disk (MPIO dans notre cas) et enfin les stacks Storport (pour la gestion de la partie SCSI). Pourquoi ? parce qu’une IO à destination de notre LUN va traverser un file system (NTFS\FAT et tous les File System minifilter drivers), puis un volume, puis va traverser un disque multi-path (MPIO) pour ensuite atteindre une LUN sous la forme d’une commande SCSI à destination du stockage.


    Commençons par la stack file system. Le point d’entrée de la stack File System se trouve être le DeviceObjectde notre commande !vpb (voir plus haut) :


    1: kd> !devstack 0xffffe000adb30030

      !DevObj           !DrvObj            !DevExt           ObjectName

      ffffe000ad961780  \FileSystem\FltMgr ffffe000ad9618d0 

    > ffffe000adb30030  \FileSystem\Ntfs   ffffe000adb30180 

    Nous savons donc que la LUN a été formatée au format ntfs car il y a un device ntfssur la stack. Il y a également moyen de récupérer tous les filter drivers file system à partir du device fltmgr(Filter Manager) mais ce sera l’objet d’un autre article. Une stack va se lire de haut en bas. i.e. pour notre stack file system, une IO va passer d’abord par fltmgr.sys (et tous les minifilter drivers file system) puis par ntfs.sys. Nous en sommes ici pour le moment :



    Poursuivons avec la stack volume :


    1: kd> !devstack 0xffffe000adb4bac0

      !DevObj           !DrvObj            !DevExt           ObjectName

      ffffe000adaf7040  \Driver\volsnap    ffffe000adaf7190 

    > ffffe000adb4bac0  \Driver\volmgr     ffffe000adb4bc10  HarddiskVolume3

    !DevNode ffffe000ad6c7360 :

      DeviceInst is "STORAGE\Volume\{82402ec9-6156-11e5-89cc-00fec8f70d10}#0000000000100000"

      ServiceName is "volsnap"

    Une IO va donc d’abord passer par volsnap.sys. Volsnap gère les snapshots VSS. C’est au niveau de volsnap.sys que va se prendre la décision d’aller chercher des données plutôt dans la diffarea (si tel devait être le cas, en cas de snapshot), ou plutôt sur le volume réel. Je ferai un article sur le sujet plus tard. Si une IO doit continuer son chemin vers notre LUN, alors elle va passer par le driver volmgr.sys.





    Nous allons maintenant traverser la stack disque. Comme le multi-pathing a été activé, notre disque sera un disque MPIO. Pour faire le lien entre le volume et le disque, il va falloir aller chercher l’information dans la structure DEVICE_OBJECT_EXTENSION de notre volume. Chaque DEVICE peut maintenir une structure (DEVICE_OBJECT_EXTENSION) pour stocker des informations qui lui sont propres. Les structures en question étant non-publiques, nous allons devoir retrouver l’information en tâtonnant. Il faut dans un premier  temps rechercher les adresses qui correspondent à la structure de type DEVICE_OBJECT_EXTENSION de notre device volume. Pour se faire, il suffit d’utiliser la commande !devobj sur notre device volume puis de dumper les adresses comprises entre le champ DevObjExt (en rose) et DevExt (en bleu). Nous avons donc :


    1: kd> !devobj ffffe000adb4bac0

    Device object (ffffe000adb4bac0) is for:

    HarddiskVolume3 \Driver\volmgr DriverObject ffffe000abe2cc00

    Nous avons à l’offset 0x168ce que nous recherchons (faites-moi confiance). Si d’aventure dans une version ultérieure de Windows cette structure devait changer, vous pouvez toujours essayer de retrouver notre device en tâtonnant avec une commande !pool pour retrouver un pool tag de type Devi.

    Notre stack disque ressemble donc à ça :


    1: kd> !devstack ffffe000`adb70060

      ServiceName is "disk"



    Ce qui nous donne le schéma suivant:



    Pour continuer, il faut maintenant rechercher le nombre de paths, et les découvrir. Comme pour le device volume, la structure n’est pas publique mais peut être retrouvée en tâtonnant selon la même technique s’agissant de MPIO. Nous avons donc :

      ServiceName is "disk"

    Il s’agit ici de disques iSCSI vers une baie de disque QNAP. Le driver mini-port storport dans ce cas est celui de Microsoft (msiscsi.sys). S’il avait été question de LUNs  fiber channel, nous aurions eu des devices QLogic ou Emulex (i.e. du code non Microsoft).

     Ce qui nous donne le schéma suivant:





    Pour résumer : 2 LUNs ont été présentées à Windows pour attaquer le même disque coté baie mais via 2 chemins différents (redondance). Ces 2 LUNs ont été « multipathées » coté Windows ce qui fait que le disque manager ne voit qu’un disque (le disque MPIO). Les IOs (si elles ne peuvent être résolues par le cache), vont traverser l’ensemble des devices\drivers depuis fltmgr.sys jusqu’au miniport storport pour transfert via la carte HBA ou adaptateur réseau (si iSCSI).

    Si le multi-pathing est paramétré pour faire du round-robin (d’autres modes existent), alors les IOs seront distribuées successivement vers une LUN puis vers l’autres etc…
