Remote Desktop with 1366×768 resolution

Since I got my new laptop (XPS 14z) I’ve been running into the following annoying problem.
When I minimalize my full screen remote desktop session it’s not possible to maximize it back again.It would maximize to a window size smaller than my monitor so I have to scroll to see everything from my session. Especially when you got multiple sessions and quickly want to check some things on your local computer this can be really annoying.

Remote desktop to XenServer VM via PowerShell

Recently I wrote a PowerShell script that connects to the console of a virtual machine on a Citrix XenServer, without using XenCenter or the Web Self Service portal. This allowed me to offer a published application to my users so they can connect to the console session. But what if they want to connect via a Remote Desktop Connection (RDP)?

I’ve written a PowerShell script that looks up the IP address of the VM and connects via RDP.

Traag RDP verkeer met Windows 7

In het eerste lange weekend van het jaar heb ik eindelijk besloten mijn laptop opnieuw te instaleren. Dit is voor een IT’er een exercitie die je één keer per 1-2 jaar uitvoert.
