Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Back up the registry before you edit it.

  • Download the appropriate registry settings file that is attached to this article and import to a client device.
    Note: The attachment contains the file for a 32-bit or a 64-bit operating system.

    – Or –
    HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\ICA Client\Client Selective Trust.

Resource Key Resource Description
FileSecurityPermission Client Drives
MicrophoneAndWebcamSecurityPermission Microphones and Webcams

Slow Application Authentication, Enumeration, and Application Launch with Citrix Receiver for Apple IOS Devices

Symptoms

When using an iOS device such as iPhone, iPad, you might experience one of the following issues when connecting to your XenApp Services site in a XenServer environment:

  • The iOS device intermittently fails to make a connection to the XenApp Services Site. (times out).
  • When attempting to connect to the XenApp Services Site, the authentication and enumeration process would take an excessive amount of time to complete.
  • When the Authentication process has completed and the published applications are enumerated, not all the applications that the user has access to are displayed.
  • When attempting to start an application from your Services Site, you might receive Protocol Driver Error.

Cause

The problem is caused by the XenServer PV Ethernet Adaptor Advanced Offload Properties.

When you install the XenServer virtualization drivers, the network interface has the following four Offload adaptor settings:

  • Large Send Offload
  • Offload IP Checksum
  • Offload TCP Checksum
  • Offload UDP Checksum

Resolution

As a workaround, you can just Disable all the four properties. No restart is required.

Make these changes on your XenApp, Citrix Secure Gateway, and Web Interface servers. Once these changes are made, you should be able to connect with your iOS devices quickly and without any issue.

Status

This workaround applies to Windows Server 2003 and 2008. This issue does not affect Windows Server 2008 R2.

Executive Summary

Desktop virtualization has grabbed the attention of the global IT community like never before. Server and desktop virtualization let IT simultaneously offer lower costs and greater access to the employees. The Bring Your Own PC (BYOC) movement, along with technologies such as XenDesktop and XenClient provide an opportunity to use any device – even computers owned by the employee – and work on the corporate desktop from anywhere, anytime.

The convenience and cost benefits of “work-shifting”come with its own set of challenges for corporate IT—two of those being security and user-experience. A significant number of remote users access virtual services from insecure locations, such as coffee-shops, airports, hotels and homes. These internet connections often have lower speeds, higher latency, and packet loss. Citrix XenDesktop and XenApp use the HDX™ technology to ensure high definition user-experience, no matter where the user works.

HDX WAN Optimization powered by Citrix Branch Repeater and HDX SmartAccesspowered by Citrix Access Gateway are integrated into the XenDesktop solution. Using the Repeater plug-in together with the Access Gateway plug-in, mobile users enjoy accelerated, secure remoteaccess to XenDesktop and XenApp. This paper describes the enhanced experience enjoyed with this “turbocharged Citrix” environment.
