Citrix XenApp failed to connect to the Data Store.

Today I needed my XenApp 6.5 server to check something in my lab and I wasn’t able to run the discovery of my XenApp farm. I checked the services and they were running fine (IMA, MFCOM etc). In the event log however I saw these nice messages: Continue reading “Citrix XenApp failed to connect to the Data Store.”

Worker Group Membership Changes Prevent Users from Launching Applications

Here’s another issue I encountered during my work at Citrix which I wrote a KB article for.

The issue is when an application is assigned to a worker group and the membership is changed of that worker group the application launch fails.

Change Worker Group assignments

When an application is assigned to a worker group and the membership is changed of that worker group the following symptoms are visible:

  • Newly added servers to the Worker Group are not used for launching the application
  • The application fails to launch displaying the following error message to the user: Connection Error: You have not been granted access to this published application OK
  • Disabling and re-enabling all applications would fix the error.

Resolution

Install the hotfix in CTX135783 – Hotfix XA650R01W2K8R2X64052 – For Citrix XenApp 6.5 for Windows Server 2008 R2 – English to fix this error.

Unable to logoff XA 6.5: ICA session displaying “Waiting for System Event Notification Service”

Users cannot log off from a XenApp 6.5 ICA session and the “Waiting for System Event Notification Service” pop-up is displayed.

Requirements

  • Windows Server 2008 R2
  • Citrix XenApp 6.5
  • Office Communicator 2007 R2

Cause

The screen remains unresponsive with the “Waiting for System Event Notification Service” pop-up. On the server user has a Communicator (OCS) running and one of the instances is pegging an entire core resulting in users unable to log off sessions.

Resolution

As a workaround you can do the following: To log off successfully from the unresponsive sessions, terminate the pegged OCS process.  For a permanent solution you need to apply this fix from Microsoft Cumulative update package for Office Communicator 2007 R2: December 2012.

Differences in Client Drive Mapping between XenApp 6.0 and 6.5, Presentation Server 4.5, and XenApp 5.0

This article describes the difference between earlier versions of Client Drive Mapping (CDM) and the version in Citrix XenApp 6.0 and 6.5.

Description

Versions prior Citrix XenApp 6.0, use the method of network mapping the local drive of the user. This method only mapped local drivers, not network drivers of the user machine. For users to be able to add network driver mappings they require a script to use the net use command and locate the drives from \CLIENT. With this method, the administrator is also required to create a log off script to delete these drives when the session is logged off. On XenApp 6.0, the CDM system uses a completely different mechanism; it uses the concept of redirection; the same concept used with Microsoft Remote Desktop connections.

Simple things to know about the client drive redirection:

  • Mapped drives are classified inside the session as Network Drives; redirected drivers have no specific Windows category so they are classified as Others.

New hotfixes for XenApp Commands for Citrix XenApp 6.0 and 6.5

Here you can find the fixes which come with these releases:

Enumeration Worker Groups in AppCenter Console is slow

Today an article I wrote a while ago came online at the Citrix knowledgebase.

When trying to add a Worker Group to a policy, it may take a long time to display the list of available Worker Groups.

Background

When editing a user policy and trying to add a worker group as a filter the AppCenter console, it may take a long time (>1 min) to enumerate the list of available worker groups in the farm. The server running the AppCenter console is running Windows Server 2008 R2 with XenApp 6.5 and hotfix rollup pack 01 installed.

To add a Worker Group filter to an existing policy through the AppCenter console it can take a while for the list of available Worker Groups to appear. Complete the following steps to reproduce this issue:

  • Launch AppCenter.
  • Go to your farm and select Policies.
  • Select the Filters tab.
  • Select All Filters and search for Worker Groups.
  • Select Add to add a Worker Group to this filter.
  • Click Add.
  • Choose browse in the New Filter Element screen.

It takes up to 6 minutes to enumerate the list of Worker Groups.

Resolution

Apply the correct Group Policy Management Console hotfix on the computer(s) running the AppCenter console.

CTX135403 – LIMITED RELEASE – Hotfix GPMx170WX64002 – For Group Policy Management Console for Windows x64 – English

CTX135402 – LIMITED RELEASE – Hotfix GPMx170WX86002- For Group Policy Management Console for Windows x86 – English

After applying the hotfix and restarting your machine, Worker Group enumeration takes lesser time than before.
