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

Powershell – Check XenApp LoadEvaluator

At a customer I was busy checking the servers via the Citrix Management Console wich load evaluator was set. Because the environment contains a lot of servers it is a time consuming job. Therefor I created 2 small scripts.

The first script will do the following.

  • Add citrix powershell Snapin
  • Get a list of XenApp servers in the farm
  • Check for each server wich load evaluator is assigned
  • Write the result to a CSV fileThe second script will do the following.

Citrix Receiver – Security Warning

When you start a Citrix Session and open an explorer window the following message appears.
Citrix Receiver – Security Warning.

This message is caused by the Citrix Receiver. The Receiver is trying map the local drives and is trying to access them.
In case of a writable profile this is not a big issue. If you choose to Permit all access the settings are saved in the registry thus in the profile. When working with mandatory profiles these setting will not be preserved. Also in a ThinClient environment this behavior is not wanted. Because this will generate some helpdesk calls.

  • RES WorkspaceManager 2011
  • RES VDX (former workspace extender)
  • Windows 2003 (Legacy Farm)
  • XenApp 5.0 (Legacy Farm)

At the client side we use a HP thinclient with Windows 7 embedded with the Citrix receiver 3.0.

During the tests of the environment we experienced an error message. When starting a Citrix XenApp session with RES VDX enabled the following error might occur: “This Version of Citrix Receiver does not support the selected encryption. [Error 1046] The Virtual Driver is not loaded”. Continue Reading
