How to solve the screen flickering on a XPS 13 (2015)

  I’ve been using a beautiful Dell XPS 13 (9343) for the last 3 months as my primary machine. Not only has it a decent processor (i7), it also has a beautiful high resolution screen. The brightness and contrast is much better than on the Lenovo X1 Carbon that I’ve been using previously. But the […]

The case of the missing IP addresses

In a VMware vSphere 5.5 environment we discovered a strange issue with most VM’s. After a reboot they would lose their network connectivity. It doen’t matter if they run 2008 R2, 2012 or 2012 R2, they all show the same behavior. They are unreachable over the network In vSphere they show the correct IP address […]

High resolution user pictures in Office 365

Imagine you have a bunch of pictures of your users… and imagine that they are 648×648 pixels and are named %username%.jpg. Wouldn’t it be awesome if you could upload those in Office 365 without bothering your users with an instruction?

Slow client Hyper-V in Technical Preview

I decided my life was too easy. I’ve replaced Windows 8.1 update with Windows 10 Technical Preview on my primary machine. Overall this works pretty well, but I did run into a performance problem with client Hyper-V. When setting up a demo virtual machine with Windows 8.1 I noticed it was very slow. I use […]

Adding trusted senders to Office 365

One of the strenghts of Sharepoint is imo the user subscribed email alerts. Our SharePoint admin created a workflow that produces an email. This email contains some HTML to make it pretty. Outlook however, by default, blocks the HTML and the receivers end up with an email that’s well… ‘not’ so pretty.

Enable Lync users automatically with PowerShell

To enable a user for Lync, some admin interaction is normally necessary. To make life a bit easier, but to stay in-control at the same time, I wrote a PowerShell script. The key features are; Checks for usersobjects in multiple user defined OUs Checks if the userobjects are enabled Checks if the userobject has an […]

Who says the command line isn’t sexy?

Recently I have been doing a lot with Powershell. There is just one issue… a blue window with white text on it, it’s not really cool is it? Especially when you are running lenghty scripts, it just looks cool for geeks like myself. How cool would it be if the PowerShell window could be transparant? […]

renewing Exchange 2013 certificate fails

Recently a customer contacted me with an Exchange 2013 issue. Their Exchange certificate was about to expire and they had some trouble renewing the certificate on one of their Client Access servers. The 3rd party certificate was successfully imported and activated on the 1st CAS server, but it failed to import on the 2nd CAS server. […]

Deploying DPM 2012 agent with SCCM

Although System Center Data Protection Manager offers a way to do a remote installation of the agent, it’s far from ideal when you have to deploy the agent to several hundred laptops. Since the agent offers a silent installation, I thought it would be best to let SCCM do what it does best. I created […]
