Support DNS name resolution

Jun 19, 2013
You can configure Receivers that use the Citrix XML Service to request a Domain Name Service (DNS) name for a server instead of an IP address.
Important: Unless your DNS environment is configured specifically to use this feature, Citrix recommends that you do not enable DNS name resolution in the server farm.

Receivers connecting to published applications through the Web Interface also use the Citrix XML Service. For Receivers connecting through the Web Interface, the Web server resolves the DNS name on behalf of the Receiver.

DNS name resolution is disabled by default in the server farm and enabled by default on the Receiver. When DNS name resolution is disabled in the farm, any Receiver request for a DNS name returns an IP address. There is no need to disable DNS name resolution on Receiver.

To disable DNS name resolution for specific user devices

If your server deployment uses DNS name resolution and you experience issues with specific user devices, you can disable DNS name resolution for those devices.

Caution: Using Registry Editor incorrectly can cause serious problems that can require you to reinstall the operating system. Citrix cannot guarantee that problems resulting from incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Make sure you back up the registry before you edit it.
  1. Add a string registry key xmlAddressResolutionType to HKEY_LOCAL_MACHINE\Software\Wow6432Node\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions\Lockdown\Application Browsing.
  2. Set the value to IPv4-Port.
  3. Repeat for each user of the user devices.
