Get-brokersession | Where-Object {$_.sessionstate -eq "Disconnected" -and $_.sessionstatechangetime -lt (Get-date).AddHours(-4)} | stop-brokersession


Use this command to stop sessions that have been disconnected for 4 hours. This could be useful when the Timings you want are not accepted by the Sessions GPO setting. 

When you add an App-V sequenced package into the new XenApp 7.8 integrated App-V library, you will need to make sure that the location you are importing the packages from is a network Share.  If you do not import the package from a network share, you'll notice that the powershell command to import the package is run, but the Studio screen appears blank and the application is not added.

On further investigation,  the Studio Console Log will display "Successful" for the import.  The Windows event log will show no details of any error.  You can launch Powershell from Studio and type the command:

Get-AppLibAppVpackage

This will display a list of the imported App-V packages.  You may notice that there will be entries in there even though there is nothing in Studio.  Notice the erroneous metadata entries (Your failed import attempts) and zero package GUID information.  When you try to remove these entries using Remove-AppLibAppVPackage -UID, it will not work.  

Citrix will implement a patch for this issue, but in the meantime, please be aware that if you add a package from any location that isn't a share, it will not display an error and it may create erroneuos metadata entries.

• Check the location that you import the Sequenced Packages from is a Network Share

• Check the Citrix Application Library Service is running on the Delivery Controllers

Your XenApp/Xendesktop services may be running, but how can you check that they are working as they should?  Do the following:

Launch Studio Console from a Desktop Delivery Controller and Select the Launch Powershell option

Check each service in turn with these commands:

Get-ConfigServiceStatus
Get-BrokerServiceStatus
Get-HypServiceStatus
Get-AcctServiceStatus
Get-ProvServiceStatus
Get-AnalyticsServiceStatus
Get-MonitorServiceStatus
Get-AdminServiceStatus
Get-logServiceStatus
Get-SfServiceStatus
Get-EnvTestServiceStatus
GetADIdentityService

If they return as "OK", then it indicates the Service is running and connected with the database.

You have created a shared start menu for your Hosted Shared Desktops, but you notice that the start menu groups and tile locations are not being applied for your users.  So you Logon as an admin and pin your apps to the tile menu again and create start menu groups. You make sure that the Start menu folder redirection is configured to Move the contents of your Start Menu to the shared start menu location.  You wish to use the Start Menu layout setting in Group Policy so that your Start menu tile format can be exported to XML and loaded for all users. You notice that the GPO setting isn't available because you are using 2008 AD servers. So what can be done? Follow this procedure to test a solution:

Make sure that you have already created the redirected Start Menu on a file share that has Access Based Enumeration enabled. Make sure that you have pinned all of your apps to the start menu and created any start menu groups

1 ) Go to DC.

2) Copy Startmenu.adml & admx files into same folder location and rename the copies to startmenubackup

3) Run the installer for the Win 8 2012 GPOs on the DDC with the GPMC console installed

4) C:\Program Files (x86)\Microsoft Group Policy\Windows Server 2012\PolicyDefinitions
Copy Startmenu.adml &  Startmenu.admx from Desktop Delivery Controller  "C:\Program Files (x86)\Microsoft Group Policy\Windows Server 2012\PolicyDefinitions"  to Domain Controller Policy Central Store

5) Overwrite existing files.

6) Go to your Start Layout Policy and check that "Start" or "Start Layout" GPO setting is available in Users\Admin Templates\Start Menu & Task Bar

7) Export your Start Layout using:

8) export-startlayout –path “\\YourStartMenuShareLocation\StartLayout.xml” -as xml

9) Edit the "Start" Layout GPO setting to point to the path that your XML file is located in (as above)
May have to copy Start Menu.adml and ADMx files into the c:\windows\policydefinitions of your Server 2012 controller and edit the GPO settings on there if you have no 2012 DCs.

10) Apply the policy and test.  You should see the apps that your user has access to and the start menu layout should include the Start Menu groups you created
