Citrix ICA

From ThinManager Knowledge Base
Jump to: navigation, search


ThinManager thin clients can use either the Microsoft RDP or Citrix ICA protocol to communicate to the session. This option is enabled in the Terminal Server Configuration Wizard and is selected in the Display Client Configuration Wizard. For information related to installing Citrix Xen App, see the ThinManager and Xen App 6 Fundamentals Article.

Limitations of Citrix ICA Display Clients

  • Due to configuration constraints with newer versions of XenApp / XenDestop, ThinManager supports Citrix installations through XenApp / XenDesktop 6.5. Version 7.0 and later are not currently supported.
  • Many ThinManager features are not compatible with ICA Display Clients. Much of Relevance, tiling, session scaling, among others, are not compatible with this display client type.
  • ICA Display Clients are currently only supported on physical thin clients. It is not supported on WinTMC, iTMC, or aTMC.

Display Client Configuration Wizard

A Display Client (formerly Application Groups or Terminal Server Groups) can be configured to use the ICA protocol on the Terminal Services Display Client Type page of the Display Client Configuration Wizard.

The Citrix ICA page has a few settings for configuration:

  • Encryption Level – This drop-down sets the Citrix encryption level.
  • ICA Browser Address – Entering the ICA browser address aids in connection across routers, subnets, and domains.
  • Use a Citrix Published Application – This checkbox, if selected, will allow usage of Citrix Published Applications to deploy programs to the thin client.
  • Enter the name of a Published Application - This field allows the desired published application to be designated when the Use a Citrix Published Application checkbox is selected.

Note: Published Application should have a continuous name and not contain spaces.


If the Display Client is using a Citrix Published Application the wizard will finish with this page.
If the Display Client is not using Citrix Published Application the wizard will continue to allow the selection of Terminal Servers that are configured to use the ICA protocol.

Terminals Using Display Clients with ICA

If a terminal is using the display clients to receive applications then display clients will show up in the Available Display Clients list on the Display Client Selection Page.

Select the desired Display Clients from the Available Display Clients list and move them to the Selected Display Clients list. The terminal will use the Display Clients selected, both RDP and ICA.

Terminal Using Citrix and Individual Terminal Servers

Using individual terminal servers instead of Display Clients (Application Groups) is supported but not recommended. If you are using the legacy method of using individual terminal servers instead of Display Clients you need to configure the terminal to use ICA servers.
Double click the icon of the terminal in the ThinManager tree to open the Terminal Configuration Wizard. Select the Next button to navigate through the wizard to the Terminal Connection Type page.
