XenDesktop 7.6 Multiple Screen with Desktop Viewer

By default when Desktop Viewer is enabled, it does not span on multiple screen. When it is maximizes, it only maximizes on one screen. To have it utilizes multiple screen, do:

Enable Desktop Viewer
Login to your StoreFront Server
Navigate to C:\inetpub\wwwroot\Citrix\<your store or receiver web>\
Edit web.config
Find showDesktopViewer="true" and make sure the value is true, not false

Enable Force Full Screen
Login to your StoreFront Server
Navigate to C:\inetpub\wwwroot\Citrix\<your store>\App_Data\
Edit default.ica
Find [Application] 
Add DesktopViewer-ForceFullScreenStartup=true under that tag

Propagate your change across your  Server Group

XenDesktop 7.5 Publish Application to Multiple Delivery Group

Recently I deployed XenApp/XenDesktop 7.5 environment with StoreFront 2.5. By default, using the GUI console, it only allows you to publish an application to a single Delivery Group.

If you have 4 servers and 2 delivery groups, and in each delivery group, 2 servers are registered, with this configuration in mind, you can only publish a particular application to a single delivery group, which equals to 2 servers only.

There was a requirement to be able to publish an application to all the 4 servers within 2 delivery groups. Apparently this is not possible using the GUI console.

However, using PowerShell you can !

You publish the application to the 1st delivery group using the GUI console, then you publish to the 2nd delivery group using the following

Add-BrokerApplication -Name "My Published App" -DesktopGroup "Delivery Group 2"

Note: There is a bug with this, which I believe is fixed with 7.6. The bug is if you were assigning a user to only a single delivery group, that user won't be able to see any of published application assigned to him/her. The user must be assigned to both delivery group.

Citrix PS or XenApp Data Store Move - Domain Service Account

To move Citrix SQL data store from one server to another and using domain service account rather than SQL built-in account, follow the process below

• Stop IMA services from all Citrix servers
• Backup the database from the source SQL server
• Restore the database to the destination SQL server
• Add the domain service account to the SQL server and assign dbo rights to the database that just been restored
• Edit the MF20.DSN file on each Citrix Server and make sure the following value exist

UID = DOMAIN\USERNAME
Trusted_Connection=Yes
DATABASE=SQL-SERVER-DATABASE-NAME
WSID=CITRIX-SERVER-NAME
SERVER=SQL-SERVER-NAME[\INSTANCE]

• Save the MF20.DSN file
• Run the following command

dsmaint config /user:DOMAIN\USERNAME /pwd:PASSWORD /dsn:"FULL-PATH-TO-MF20.DSN FILE"

Note: /dsn: requires double quote ""

Then run this:

dsmaint recreatelhc

Then Start the IMA Service

Citrix XenApp Management Console Bug

Citrix XenApp 5 or 4.5FP2 has got a bug - when you launch CMC and run the discovery, it does not find the XenApp farm, only the Web Interface module.

To fix it, run the following:

cd %CommonProgramFiles%\Citrix\*Present*
%windir%\microsoft.net\framework\v2.0.50727\regasm /codebase pse.core.dll
cd %CommonProgramFiles%\Citrix\*Framew*
CmiLaunch.exe

Run the discovery again and it should find it now
