From the release of Windows Server 2008 you can choose when you install the OS between the Full or the Core version of Windows. The Core version has most of the functionnalities of the Full but lose its graphical interface (GUI).

In this particular configuration, most of Windows administrator will be lost. You can hopefully manage remotely the server using the well known MMC consoles but there are a lot of basic tasks that will require manual configuration.

If you try this savor you’ll find some included scripts to enable/disable Windows Update or Remote Desktop but that’s all.

There is however a tool named “Core Configurator” available in 2 version (2.0 for R2 and 1.1 for R1) that enable you to easily configure your Server Core.

The following can be done:

• Product Licensing
• Networking Features
• DCPromo Tool
• ISCSI Settings
• Server Roles and Features
• User and Group Permissions
• Share Creation and Deletion
• Dynamic Firewall settings
• Display | Screensaver Settings
• Add & Remove Drivers
• Proxy settings
• Windows Updates (Including WSUS)
• Multipath I/O
• Hyper-V including virtual machine thumbnails
• JoinDomain and Computer rename
• Add/remove programs
• Services
• WinRM
• Complete logging of all commands executed

There is another tool (in command line this time) named Core Configuration Console R2 (also exist for R1). It does most of the jobs (perhaps more than Core Configurator) and it’s worth having a look on it.

Keep in mind that you can also manage Server Core using:

• GPO (for Firewall settings, WSUS, Service configuration, screensaver etc.)
• Custom scripts (in PowerShell since Windows Server 2008 R2) so they can be reusable and be part of your documentation (it’s always easier to launch a script than going through multiple screens)

Amateurs de bonne cuisine ou tout simplement amateurs de bons plans, je tenais à vous faire découvrir ce site :

LaFourchette propose un guide de restaurants (surtout sur Paris mais pas que) avec les avis des utilisateurs et se propose de réserver pour vous une table.

Le gros point fort du site repose sur ses promotions où on trouve régulièrement des bons plans du type :

• -50% sur l’addition
• Cocktail offert
• Une bouteille de vin offert (bon faut voir la bouteille après)

Donc si vous voulez déjeuner/diner dans des restaurants haut de gamme pas cher, pensez à ce site (ça fait un peu pub mais non je ne touche aucune commission).

Merci à Laurent pour m’avoir fait connaitre ce site.

TrueSec, a consulting/training company in US and Sweden, well known for their experts has published a series of guides about deployment of Windows 7 using Lite Touch and Zero Touch deployment method.

These guides (in video and PDF format) show you how to deploy a PoC (Proof of Concept) from installing the environment (SCCM, SQL, MDT 2010), through capture a reference computer, deploy it afterwards, personalize images.

This is worth to look at it. It leverages the latest technologies :

• Windows 2008 R2
• SCCM 2007 R2 SP2 + WSUS
• SQL Server 2008
• MDT 2010
• Windows 7

It is from my point of view a good opportunity to discover what these products can do for you.

The link to download these guides (as a iso file) is here : http://www.deploymentcd.com/

PowerShell utilise la puissance du Framework .Net et permet donc d’utiliser les classes de celui-ci avec une très grande facilité dans vos scripts.

Dans cet exemple, je vais vous montrer comment faire une résolution DNS à partir de la classe Net.Dns du Framework.

[System.Net.Dns]::GetHostentry("blog.paux.fr")

Le résultat sera (en fonction si votre entrée est un simple alias ou un vrai nom d’hôte) :

HostName                  Aliases            AddressList
--------                  -------            -----------
dedibox2.jeanb-net.com    {}                 {88.191.92.204}

On peut biensûr décorer un peu tout ça en pipant une liste de nom d’hôtes depuis un fichier, rediriger ça dans une grille via out-gridview (nouveauté PS2.0 !). (A noter que si vous voulez non pas avoir le nom d’hôte mais vraiment votre input, vous pouvez le rajouter via la commande Add-Member, testez avec et sans vous verrez).

gc .\hosts.txt |% { [System.Net.Dns]::GetHostentry($_) | Add-Member -Name Host -MemberType NoteProperty -Value $_ -PassThru } | Select Host,AddressList | out-gridview

On peut biensûr faire des résolutions inverses (IPv4 ou IPv6).

[System.Net.Dns]::GetHostentry("2001:4860:a005::68";)

La classe Dns du Framework reste sommaire, il n’est pas possible de résoudre autre chose que ça (impossible de récupérer les NS, MX, SOA, TXT etc.) mais on peut pour cela utiliser d’autres classes qui implémentent un autre resolver (ou utilisant de manière plus approfondie celui de Windows)

PowerShell uses the power of .Net Framework thus you can leverage .Net classes in your PowerShell scripts.

In this example I’ll show you how you can perform DNS lookups using the Net.Dns class :

[System.Net.Dns]::GetHostentry(“blog.paux.fr”)

The result will be (depending if your input is a A or CNAME) :

HostName                  Aliases            AddressList
--------                  -------            -----------
dedibox2.jeanb-net.com    {}                 {88.191.92.204}

You can obviously pipe a list of hostname to this command and if you need to keep the original name you can add it to the resulted object and display it in a grid (new to PS2.0 !):

gc .\hosts.txt |% { [System.Net.Dns]::GetHostentry($_) | Add-Member -Name Host -MemberType NoteProperty -Value $_ -PassThru } | Select Host,AddressList | out-gridview

You can of course do the same with an IP address (or an IPv6 address):

[System.Net.Dns]::GetHostentry("2001:4860:a005::68")

The class in .Net Framework stay basic so you can’t resolve NS, SOA, MX or TXT records for example but you can try to use other classes as this implementation of a resolver in C# or using this one (that use the internal DNS resolver of Windows)

Microsoft released last week Office 2010 Technical Preview on Connect and it is time to speak about it !

I really appreciate this new version, for a lot of reasons (conversation display in Outlook, improvements of UI in most of apps of the suite etc.) but I’d like to emphasis on one improvement I was asking for a long time : the ability to have multiple Exchange Accounts in the same Outlook process (without using App-V, run-as or other tips to launch multiple Outlook).

You can ask why do I have 2 Exchange accounts, but it is simply because I’ve got my Avanade corporate account and my personal Exchange server (Exchange 2007 but soon Exchange 2010)

So how to do this ?

1. Close Outlook
2. Go to control panel
3. Search “Mail”
4. Click on New Account
5. Enter your account settings (and use Autodiscovery !)
6. Launch Outlook

As you can see it is really straightforward so abuse of it !

I’ve got now my two Exchange accounts, as we had before for POP/IMAP :

If you often use PowerShell as script language you well know the out-* and export-* cmdlets.

I often use export-csv and open the result in Excel or out-GridView in PowerShell v2 (useful cmdlet BTW) for a nice graphical interface. I sometime use Excel API to create an Excel sheet directly or to import data but something was missing : simplicity.

These are an excellent solutions but why don’t we use Excel directly with an out-excel cmdlet ?

I just found this cmdlet there : http://pathologicalscripter.wordpress.com/out-excel/ and it is working very well ! So have fun using it.
