Disable “Allow the computer to turn off the device to save power” for all WiFi adapters

Written by Ingmar Verheij on May 1st, 2014. Posted in Other

When a Windows computer enters sleep mode it ensures that WiFi adapters enters the device power state D3 (Sleep) and on resume ensure it puts it back to the device power state D0 (Full on).

Windows assumes that if a driver says it supports sleep states it handles this correctly, but this setting is known to cause some spontaneous disconnects with the access point (AP). Optionally Windows can be configured to place the WiFi adapters in device power state D4 (Off).

I wrote a PowerShell script that disables the “Allow the computer to turn off this device to save power” setting for all WiFi adapters (contact me if you want it to disable ALL network adapters).

Run and compile .NET code in RES Workspace Manager (using PowerShell)

There are occasions where you need a custom solution to fulfill a requirement which cannot be solved with existing applications or tools. This is usually where scripting comes into the picture, nowadays we tend to built most scripts using Microsoft PowerShell as it’s a very powerful framework with a huge repository of cmdlets. Nonetheless there are situation where PowerShell has no built-in cmdlet (or third party cmdlet is available) and you’d have to revert to API’s or .NET code.

Wouldn’t it be a shame if you’d have to write and compile .NET code using an IDE like Visual Studio before you can use that code? Well, there’s a solution!

Building a lab server

Written by Ingmar Verheij on April 29th, 2014. Posted in Other

Working in IT means you never stop learning, change is all around. To keep up with developments and to try out new ideas it’s essential to have a lab environment where I can play around with different technologies.

In the past I’d had a lab environment running in the cloud but I felt limited not having direct access to the hardware. While I have no intention to start experimenting with virtual GPU sharing yet, I might in the future. So I decided it was time to invest in a lab server to run at home. Since the server runs physically runs at home it needs to have fairly high wife acceptance factor (WAF). A stylish design, low power, low noise and fairly affordable server is desirable.

Citrix XenApp or XenDesktop: A decision tree

Citrix XenApp or XenDesktop: A decision tree

Citrix offers two products to deliver hosted resources to users: XenApp and XenDesktop. Although the products share great similarities (and since v7.x the underlying architecture is now common, FMA rather than IMA),  have their unique characteristics.

What product do you need? When and why? In this article I’m trying  to help you make this decision based on a decision tree.

During the course of this article I’m assuming you’re designing a XenApp / XenDesktop 7.x environment, however the principal is equal for XenApp 6.x and XenDesktop 5.x.

Citrix released “XenBroker 7.5”

Rest In Peace - Citrix XenAppIn 2013 Citrix merged their application and desktop delivery solutions XenApp and XenDesktop into XenDesktop 7. XenDesktop 7 (XD7) combined the ability to provide remote access to single- and multi-user Windows platforms improving their FlexCast technology.

Besides that we got rid of the ancient IMA architecture, what I liked most was the fact that there’s  now one single product to offer access to single- and multi-users applications AND desktops: XenDesktop. Nonetheless we had to let our beloved XenApp go. After numerous evolutions and name changes (WinFrame >> MetaFrame  >> Presentation Server >> XenApp) this was the end of an era. But, Citrix did skip the cursed version 6 for the XenDesktop product range. Hooray!
