Slow application start times VMware UEM and App-V

When users need to wait for 60 seconds until they can interact with the application the user experience is impacted. We encountered this behaviour at a costumer and needed to troubleshoot this.

To read more on how I found the problem by excluding antivirus and group policy settings see my guest blog post at Logit Blog

App-V 5.0 registry import not working using dynamic config

A few weeks ago I called my colleague Ryan Bijkerk of www.logitblog.com with the question can VDI tuning break App-V? This inspired him to write a nice article on how performance optimization van break App-V which can be found here.

Within our company we are using VDI for desktops and App-V 5.0 for application virtualization.  Also we did some performance tuning on the VDI’s. Everything was working fine until we we got an App-V application with a registry import via the DynamicConfiguration.xml. First I thought this was an issue with one of the settings we did with the performance tuning maybe we disabled a services that was needed. This was the reason for my call with Ryan.

So I started my troubleshooting by enabling the disabled services without any luck. The registry import was still not working. So I started Googling and I came a cross the following site http://www.app-v.info which let me to the Blog of Trentent. His blog provide the solution by setting the following value:

Registry location: HKEY_LOCAL_MACHINE\Software\Microsoft\AppV\Subsystem key:
Value: NoBackgroundRegistryStaging
Data Type: DWORD
Data: 0

You can read the full article here about the the registry value.

7.6, XenDesktop

Generic USB devices XenDesktop 7.6

USB devices are automatically redirected when USB support is enabled, and the USB user preference settings are set to automatically connect USB devices.

In Receiver for Windows 4.2, USB devices are also automatically redirected when operating in Desktop Appliance mode, and the connection bar is not present. In earlier versions of Receiver for Windows, USB devices are also automatically redirected when operating in a desktop appliance mode or with Virtual Machine (VM) hosted applications.

However, it is not always best to redirect all USB devices.

PowerShell 3.0 stopped working!?

In a Citrix XenApp 6.0 environment I use a lot of powershell scripts to get things going. For example during logon of a user some scripts are used to copy program settings to the user profile. Under PowerShell 2.0 everything went fine.

After the release of PowerShell 3.0 we updated the environment with the latest version of PowerShell including the required full installation of Microsoft .NET Framework 4. Everything worked out great. All the scripts worked. Until a week ago. Continue Reading

Prevent users saving items on the Citrix/Terminal Server desktop.

In my current environment we allow users to save items on their desktop. Because we are using mandatory profiles we save the settings using Flex profiles from Immidio.

Lately some users are complaining that the logon times are increasing. After some investigation we came to the conclusion that the users are saving a lot of files to their Citrix/Terminal server desktop. The flex file would be around the 8 GB. My manager asked me to come up with a solution so that the users aren’t able to save files to their desktop but allow them to save shortcuts. Continue Reading

Automation Machine for Hosted Desktops – Cache Cleaner Tool

At a customer we are using Login Consultants Automation Machine for Hosted Desktops (Former Solution 4). Automation Machine (AM) is described as Management of Citrix and Microsoft desktop infrastructures for experts, by experts. This tool is using powershell foundation and it is based on scripts and XML configuration files. For some parts like software installations and printer driver installations AM will use a cache file. In the cache file AM will keep entry about the installed applications or print drivers. When an entry is present in the cache file AM will not install that peace of software or that driver anymore. That can give some problems with testing. Therefore I created a simple tool that can delete an entry from the cache file. Check my blog post: Automation Machine Cache Cleaner

Citrix XenApp 6.5 disaster recovery

High availability is always a hot topic at the customer but one thing is often forgotten. Disaster Recovery.

Recently I had a disaster recovery test on a Xenapp 6.5 environment. Scenario, delete all components.

Before starting I had to make sure that the backup was completed successfully. After deleting all components, VM’s, Databases etc… I started the restore. First I started to restore the Operating Systems then I restored the database for XenApp 6 after that I started an unattended install of XenApp 6.5 DataCollector by Login Solution 4. After the installation of the DataCollector I did a check to see if the farmsettings, farmpolicies and all other settings are restored again. Continue Reading
