Exam dumps
Unfortunately I’ve received numerous requests for an exam dump of 74-409 which really upsets me.
For those that are not aware of it, you are not allowed to share or use exam dumps. “If Microsoft learns that a candidate used a “brain dump” site to prepare for an exam, this candidate will be permanently banned or prohibited from taking any future Microsoft Certification exams and may be decertified from the Microsoft Certification Program. In addition, test scores and certifications, if applicable, may be revoked. These actions may be taken even if the candidate did not intend to defraud the Microsoft Certification Program.”

Preparing to take the exam
This is generally what I do for preparing to take the exam:
- Determine the skills that are measured in the exam 74-409
- View the online course Server Virtualization with Windows Hyper-V and System Center at Microsoft Virtual Academy (MVA)
- Reflect how confident you are that the online course has provided you with sufficient skills to take the exam.
- Optionally enhance your knowledge using:
- If you (know someone who) attended the course for this exam (20409A-ENU), then be sure to take a look at the book. It contains a lot of details that are missing from the jump start videos.
- Windows Server 2012 R2 Private Cloud Virtualization and Storage Poster and Mini-Posters
- Community/user created content for taking the exam
–Study resources 74-409 Server Virtualization with Windows Server Hyper-V and System Center
–Born To Learn wiki
–Veeam Study guide
–Free MCP Training study guide (in progress)
- Blogs by people that already took the exam, to see how they prepared.
- Recordings and slides of the Virtualization IT Camp
- Additional Hyper-V and Server 2012 R2 related courses on Microsoft Virtual Academy (MVA)
- Real life or virtual meetings, presentations and user groups. Microsoft has started a Microsoft User Group Portal wiki, but unfortunately it’s not widely being used yet. Therefore I suggest searching the internet or taking a look at the Microsoft Events website.
- Your own lab to work with the products. You can use the existing Microsoft Test Lab Guides (TLG) or if you don’t have the hardware for your lab, just browse the document.
- Technet library documentation about Hyper-V. This can also be downloaded here for offline use.
- Technet TechCenter
- Training videos. By example on YouTube, or from commercial companies like CBT Nuggets and PluralSight. Nowadays you can get monthly subscriptions or just get trials for a couple of days to help you get a good start.
- Great TechNet Blogs.
- Guided labs / guided experiences like by example the Microsoft Private Cloud Guided Labs. Note: these might not be updated to 2012 R2 yet, but they should provide you with a better understanding.
- Virtual labs (search for hyper or virtual machine manager)
- Twitter by following people with interesting information on Hyper-V, by searching for tweets containing hyperv or hyper-v or by connecting with the community.
- Forums to discuss and share information. Since I’m from the Netherlands I use Tweakers.net a lot and can be found discussing Microsoft Certification related stuff in the topic “[Microsoft Certified] Ervaringen en discussies”.
- Windows Server 2012 Hyper-V Best Practices (In Easy Checklist Form)
- Free e-books:
–Introducing Windows Server 2012 R2
–Microsoft System Center Microsoft System Center
–Windows Server 2012 R2 Overview White Paper
–Windows Server 2012 R2 Server Virtualization White Paper
- Printed books, but as far as I know there are no specific books yet for 74-409 and most books covering Windows Server 2012, Hyper-V or System Center 2012 have not yet been updated to the R2 release.
- Channel 9 to search for relevant content.
- Technet Video to search for relevant content.
- Server Posterpedia Windows store app or component architecture posters.
- Infrastructure Planning and Design (IPD) Guides
- Survival guides

Today I helped a colleague troubleshoot a couple of systems were unable to activate using Key Management Service (KMS). Basically for this situation it boiled down to this:
Determine for the KMS service
- Which server is hosting the KMS service.If an SRV record has been added for KMS DNS auto discovery, run from CMD: nslookup -type=srv _vlmcs._tcp
- If the server hosting the KMS is functioning correctly:
- Check if the server is up and running.
- Check if the “Software Protection” service (sppsvc) is running.
- Verify if the KMS service is listening on port 1688: telnet localhost 1688
- Verify the KMS status. Run from CMD: slmgr.vbs /dli
- Verify if a KMS key is installed and activated.
- Verify if the minimum threshold for activation is being met.
- Verify if other clients are able to activate using KMS. Even though the output of “slmgr.vbs /dli” gives you an indication, you can use the “Volume Activation Management Tool” (VAMT) for more insight and functionality.
- Verify that a VLK key is being used.
For clients that are not able to activate
- Verify if the correct KMS server can be resolved correctly:
nslookup -type=srv _vlmcs._tcp
- Verify if the KMS can be contacted:
telnet <KMS FQDN or IP> 1688
- If this is not the case, perform a traceroute to determine potential causes. Reasons could include:
- No default gateway configured on the client to reach the KMS.
- No route configured on the client to reach the KMS.
- Firewall on the client is blocking the traffic.
- Firewall on the server is blocking the traffic.
- If it is a VM, the virtual network might be misconfigured.
- Routing on the network is not correct.
- Firewall on the network is blocking traffic.
- Clear any previous (mis)configuration: slmgr.vbs /ckms
- Attempt activation: slmgr.vbs /ckms
NOTE: If you have lots of systems where you need to clear configuration and then attempt activation, you can also perform slmgr.vbs on remote computers using:
slmgr.vbs TargetComputerName [username] [password] /parameter [options]

The last couple of months I’ve been playing around a lot with PowerShell and I’ve also been trying to make some nice GUI versions for my script using PowerShell Studio 2012 from Sapien Technologies Inc. While looking for more information how to best use PowerShell Studio 2012 I came across LazyWinAdmin.
LazyWinAdmin is a great tool created by Francois-Xavier C that will save you a lot of time. It provides you with most of the commonly used tools and commands in a very structured and easy to access way. In the picture below you can see what I mean.
For more info on the tool, take a look at the website and be sure to download and test it yourself.
If you want to take a look at other useful tools I’ve found in the past, take a look at my applications list.

Troubleshooting can be very difficult and there are many different approaches and personal preferences. Also the chosen approach can even differ based on the situation.
Even though there is no troubleshooting process that is best in all situations, it is considered a good practice to troubleshoot in a structured manner.
This is why I’ve created a sample ICT troubleshooting flowchart in Visio for companies that:
- Have separate dedicated management teams for various IT disciplines like Windows, Linux/Unix, Database, Backup, Storage, Virtualization and Applications.
- Have both offshore and onshore IT personnel where all tickets are initially routed to the offshore team.
- Uses a ticketing system:
- To log events, incidents, changes, problems, etc.
- To route tickets to various disciplines.
- Use a CMDB.
- Use a change calendar.
Keep in mind that this is a sample troubleshooting flowchart that was only created to provide some structure or inspiration for troubleshooting.
I hope it is useful. If you have any ideas or suggestions, please leave a message.
PS: If you don’t have Visio, you can download Microsoft Visio Viewer 2013 from Microsoft.

In the first part of this LAB setup guide, I described the hardware selection process.
In the second part, I described the hypervisor selection and installation.
In the third part, I described VM guest considerations and preparations.
In the fourth part, I described Configuring Server 2012 VM as DC with DNS and DHCP using PowerShell
In the fifth part, I described easily creating (many) proper AD users with PowerShell
In the sixth part, I described creating a local PowerShell v3 Help Repository with PowerShell
In this post I will describe how you can make your lab available over the internet.
When you’ve created your home LAB, you want to be able to use it anywhere. Depending on your situation, one of these options probably best meets your needs.
Examples include the use of:
- Remote desktop connection to your server
+ Easy to configure (enable on server and configure NAT forwarding if appropriate)
– On many enterprise or public networks TCP3389 is blocked by the firewall.
– Connects only to specific server. Even though you access the rest of the network from there.
- VPN connection to your network
- Using your hardware router
+ Connection to network, not just a server.
– No dependency on Windows Server
- Using Windows Server 2008 / 2012
+ SSTP VPN (TCP443), is generally not blocked on enterprise/public networks.
+ Connection to network, not just a server.
– Dependency on Windows server.
– Requires more configuration.
– The root CA certificate for the certification authority (CA) that issued the server authentication certificate needs to be into the store Local Computer\Trusted Root Certification Authorities. For a self-signed certificate, this means that you need to have local admin permissions to add it.Note: DirectAccess is a great feature, but it requires the client to be a member of the domain. And in my case this would limit where I can connect from, therefore I don’t plan to use it. For other situations it might be a better solution though.
- Using 3rd party tools like logmein, teamviewer or VNC
+ Connects only to specific computer.
Since I want to be able to connect from within enterprise environments as well, I chose to use SSTP VPN in Windows Server 2012. The basic steps you have to perform, include:
- On the server, you have to install and configure the VPN service.
- On the server or your own PKI, you would want create and install a machine certificate. You can create a Certificate Signing Request and request a 3rd party public certificate. Alternatively you can create a certificate using your own Certificate Authority, or you could create a self-signed certificate, For creating the self-signed certificate you can use the great PluralSight SelCert tool.
- On the client, you have to make sure the created certificate will be trusted. This means you have to add the certificate to local system\trusted root certificate authority if you’re using a self-signed certificate, which requires local administrator permissions on the client.
- On the client, you have to set-up the VPN connection to the server. Preferably you want to connect by DNS name. For your home lab you can also utilize dynamic DNS services like by example no-ip.com or alternative solutions.

With PowerShell it is relatively easy to reverse a string:
$str = “gnirtsdesrever”
$str[-1..-($str.length)] -join “”
Some of you might ask: Why would anyone want to do this ? Well, since the start of the year Usenet DMCA takedowns have begun to occur automatically, very quickly and very often. This means many movies and TV series on Usenet / News Groups are being taken offline very quickly.
Counter measures to prevent takedowns by uploaders include:
- The use of encrypted links to NZB files.
- The use file names that make it harder to find copyrighted files.
As you can probably guess, some just reverse the file names. The PowerShell script I’ve created will automate reversing the file names for files in the specified folder that match the specified file name filter.
I hope it is useful for you as well.
PS: Someone else on usenet had the same idea as me and created a VBS that will add a right-click menu option to explorer. I’ve added this in the same location as my PowerShell script as well.

At the companies I’ve worked for , disk space on the system disk ran out on a regular basis for some systems and caused a lot of monitor calls. These kind of boring repetitive tasks are always the ones you want to automate.
So when I came across the great blog post “Weekend Scripter: Use PowerShell to Clean Out Temp Folders” on the “Hey, Scripting Guy! Blog”, I wanted to post it on my own blog as well. The blog post also describes the process of creating the script very well, which is very convenient for those who are relatively new to PowerShell to scripting and want to learn how to do it better.
If you want to take it even a step further, you could automate it even more. By example by automatically running the clean script when an event is generated that the disk is running out of space. You can configure this using by example:
Or you could use PowerShell remoting to do it on many systems at the same time. This could come in handy by example when after WSUS patching the content in “C:\Windows\SoftwareDistribution\Download” is not deleted automatically.
