Hotfix for Citrix XenApp 6.0 (Windows Server 2008 R2)

New Fixes in This Release

  1. When launching an application that is streamed to server and no ICA session exists, the IMA Service creates an extraneous two RAD*.tmp temporary files (for a total of three) at C:ProgramData. One of the files is passed to RadeRun and subsequently deleted by RadeRun. The other two files remain and accumulate over time. Only the one requisite file is created when launching a streamed to server application into an existing ICA session.[From XA600R01W2K8R2X64047][#LA0991]
  2. XenApp servers behind read-only domain controllers (RODCs) might experience slow application launch issues while winlogon.exe spikes CPU usage.[From XA600R01W2K8R2X64047][#LA1617]
  3. Clearing the “Allow connections made through Access Gateway Advanced Edition” option in the “Application Properties” of an application can prevent the Log Off or Disconnect buttons of that application from working. As a result, users cannot disconnect or close the application from the Web Interface.[From XA600R01W2K8R2X64047][#LA1670]
  4. Attempts to reconnect to a disconnected seamless session with LongCommandLine parameters can spawn an additional instance of the published application to be launched.[From XA600R01W2K8R2X64047][#LA1950] Continue reading “Hotfix for Citrix XenApp 6.0 (Windows Server 2008 R2)”

Windows 2008R2 optimization guide for desktop virtualization with XenApp 6.0/6.5

CItrix has released a nice guide how to configure Windows 2008 R2 to be at it’s best for desktop virtualization with XenApp 6.0 and XenApp 6.5.

When considering desktop virtualization with Citrix FlexCast technologies, one method for delivering services to end-users is through the use of hosted shared desktops using Citrix XenApp. Hosted shared desktops can deliver a locked down, streamlined and standardized environment ideally suited for task workers where personalization is not required. Delivering hosted shared virtual desktop requires proper planning and configuration to maximize the scalability of server resources while providing users with an optimized and functional desktop environment. This document outlines optimizations for XenApp 6 on Windows Server 2008 R2 to meet these goals. Continue reading “Windows 2008R2 optimization guide for desktop virtualization with XenApp 6.0/6.5”
