Creating a VHD vDisk from the endpoint device

image I’m deploying Citrix XenDesktop 7.1, with Citrix Provisioning Service Server, at a customer site.  The customer is using VMware 5.1 for a hypervisor. Today I am going to create the VHD file to be streamed into the VMware virtual machines and they will be delivered to the end users thru Citrix Storefront.

I’ve installed Windows 7 on a new virtual machine. After the basic Windows installation I’ve  installed the available Windows Updates.

Citrix NetScaler 10.1: Where did the Configuration Wizard go?

Configuration WizardA vanilla Citrix NetScaler shows the configuration wizard right after a users authenticates using the GUI. The configuration wizard enables basic configuration like the NetScaler IP (NSIP), Subnet IP (SNIP), hostname, DNS, Time Zone and Administrator Password.

Sometimes it’s useful to open the configuration wizard after it is closed (for instance if you want to change the host name via the GUI). up to NetScaler 10.0 there was a Setup Wizard button on the System > System Information page.

Citrix: Import NetScaler (10.1 Build 120.13) on Hyper-V Server 2012R2 / 8.1

Hyper-V did not find virtual machines to import from locationI tried importing a Citrix NetScaler Virtual Appliance on a Windows 8.1 machine and received the error “Hyper-V did not find virtual machines to import from location”. Importing the same appliance on Windows Server 2012 did work.

The cause of this error is that the virtual machine is exported from a Windows Server 2008R2 server (running Hyper-V 2) and Microsoft deprecated the WMI root\virtualization namespace v1 in Windows Server 2012 (Hyper-V 3) and removed it Windows Server 2012 R2 (see TechNet).  There’s no support for the old WMI format.

Citrix XenApp: Sessions disconnected right after connection

When new sessions are started, either via Microsoft RDP of Citrix ICA, they are disconnected within seconds. This applies to normal users and users with administrative privileges. This problem is caused by a chain of events. One components crash leads to an ungraceful shutdown of other components leaving a garbage configuration, preventing new connections.

Citrix Mobility Paris 13

On April 4th this year Citrix announced that no Synergy would be held in Europe, unlike previous years, and a new approach for the customer conference strategy was introduced: multiple regional mobility events.The article insinuated that Synergy Europe was replaced with the local conferences, starting with three mobility events (in Paris, Munich and London).

Today I’ve attended the first Mobility event in Paris with fellow peers Kees Baggerman (@KBaggerman) and Barry Schiffer (@barryschiffer) and I would like to share my experiences with you.

Redirect Registry by Modifying .NET Executable

Yesterday I was troubleshooting an application that was migrated to Citrix XenApp.

The application is able to use a high precision scale which is attached to the client pc’s com port. This com port is redirected to XenApp.

While testing users reported several issues, let’s have a look at them.

Error configuring COM Port
Within the application the comport to which the scale is connected must be configured:

De compoort lezer staat uit

After pressing "Registreer" to register the new com port the following error message was shown
