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.
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.
