Supporting DNS name resolution
You can configure Citrix Receiver for Windows 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.
Citrix Receiver for Windows connecting to published applications through the Web Interface also use the Citrix XML Service. For Citrix Receiver for Windows connecting through the Web Interface, the Web server resolves the DNS name on behalf of the Citrix Receiver for Windows.
DNS name resolution is disabled by default in the server farm and enabled by default on the Citrix Receiver for Windows . When DNS name resolution is disabled in the farm, any Citrix Receiver for Windows request for a DNS name returns an IP address. There is no need to disable DNS name resolution on Citrix Receiver for Windows.
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.
- Add a string registry key xmlAddressResolutionType to HKEY_LOCAL_MACHINE\Software\Wow6432Node\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions\Lockdown\Application Browsing.
- Set the value to IPv4-Port.
- Repeat for each user of the user devices.
