Notes from the field: XenDesktop RemotePC and Multi Licensing

Recently I got involved at a customer location which was going to use Remote PC catalogs in combination with their XenDesktop / XenApp 7.15 environment. This was no problem whatsoever to configure but on closer testing I encountered a bug that when you create for example a delivery group called “Windows 10 Remote PC” and adding more than one desktop the second, third and so on would get the published name of the local computer name e.g. WSDELL34951 which doesn’t comply with a standard name. The following can be observed for the delivery group name:Normally you would see at “PublishedName” an empty value, to correct this take a note of the “Uid” number and put in the following command:In this case my id was 4, and voila this will correct the name in StoreFront like in the following screenshot:

For the Multi Licensing part this needs to be done at the same level in powershell, see the following article:Multi-type licensing

In the previous screenshot you will see:

“LicenseModel” & “ProductCode” these need to be compliant with their respective edition of XenApp or XenDesktop license model, management is then per delivery group and not applicable for the entire site anymore. This would be a default for every new delivery group that will be created unless like in above screenshot you will add the “LicenseModel” & “ProductCode”


Hope this helps!

Notes from the lab: Windows Server 2016 black screen when launching any application

I came across an issue in my lab environment where the screen will go black while launching a session on Windows Server 2016. This is with XenApp/XenDesktop 7.15 LTSR
The following registry entry: DisableLogonUISuppression (D WORD Value 0) did not resolve the issue as stated in the following articles: and

Ultimatly after some trial and error the deletion of all subkeys from below registry entries resolved it:


Notes from the field: XenServer 7 mouse alignment MCS/PVS machines and XenServer 7 MCS XenTools

Came across two bugs on a XenServer 7 deployment in combination with XenDesktop/XenApp 7.12 worth sharing:

The first is a mouse alignment issue which results in VNC mouse pointer slowness or disalignment of the pointer on a console session in XenServer, the following can check the status of the usb and usb_tablet parameters on the vm’s:
## xe vm-list uuid=[of the provisioned machine] params=platform
which will give the output of the VM and the following command will set the value’s:
## xe vm-param-set uuid=[of the provisioned machine] platform:usb=true
## xe vm-param-set uuid=[of the provisioned machine] platform:usb_tablet=true
confirm the settings with the xe vm-list command and afterwards reboot the machine and the issue is resolved.

The second bug is in a newly provisioned MCS catalog the XenTools of all provisioned machines won’t get installed, there is a private fix for this with Citrix Support under LC6769, the definitive solution shall be updated in 7.13 according to support.
