powershell, XenApp 6.5

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.

This version of Citrix Receiver does not support selected encryption [Error 1046: The Virtual Driver is not loaded]

At a customer we are building an environment based on the following technologies.

  • Windows 2008R2
  • Citrix Xenapp 6.5
  • 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

Troubleshooting

Old-fashioned troubleshooting Windows XP(SP3)

Sometimes you have to help friends or family with there computer problems. Very often the problem is malware. Nowadays malware is a pain in the ass. It disables firewall, anti-virus, antispy- malware programs and sometimes it corrupts your TCP/IP stack. In my case the TCP/IP stack got corrupt and the DHCP Client services would not start.

WorkspaceManager

RES WorkspaceManager 2011 causes a delay when an application is started

At this moment I am working on a project for a new workspace for medical personnel. The products we are using are Windows 2008 R2 with XenApp6 for the desktop, Windows 2003 with XenApp5 for legacy apps. The workspaces will be managed by RES WorkspaceManager.
After a basic install of Windows and XenApp we installed RES WorkspaceManager Agent. After this install the servers responded slowly. Explorer, control panel and all other windows explorer windows opened after about 15 seconds. For testing purpose we removed the RES Agent and immediately the problem was solved.
I decided to contact RES Support. They came with the following solution/KB article. Continue Reading
