Citrix Client running on a terminal server

[ajbritton]

Does anyone know if it's possible to install & use the Citrix ICA Client on a terminal server?

We use an application hosted by a third party which is accessed via the Citrix client. At present this has to be installed on individual PCs and firewall changes made to enable access. We want to install the client on a terminal server and make the application available via a remote desktop session. We've been told that someone else tried this but it did not work, which surprises me. Any opinions?

Thanks,

Andy

If the terminal server is also running Citrix, yes.

I regularly run RDP sessions within ICA sessions. I also run ICA sessions within ICA sessions.

I seem to remember running ICA within RDP at some point... one sec... yep itr works

Hi Geoff,Ric, thanks for the response.

The terminal server that would be hosting the ICA client would be running Windows Terminal Services. The terminal server hosting the remote app is presumably running Citrix. I attach a diagrom of the proposed config.

It's been suggested (not by the app vendor) that the remote app would only allow a single user to connect, possibly because the connections would all originate from the same IP address.

I am following this up with the app vendor/host but these things take time?

Thanks again

IIRC a user cannot connect more than once to an application. However, each user will be running their own session so this is not a problem.

I would imagine it is more to do with the authentication at the server end and how it sees clients.

Without reconfiguring a terminal server I cannot check this out I'm afraid. Sorry for being too lazy

I guess so. Our entire network runs on private IP addresses as you would expect and is therefore NATed at the edge, but perhaps the ICA protocol carries something that is intended to uniquely identify the host machine.

I've got a the Citrix web ICA client running on our Windows 2003 Terminal servers and it runs fine.

UPDATE:

I'm told by the host/vendors of the third party app that I will need to install something called a UniPrint relay server which enables local printing from the remote app. This is so that the printing goes to the correct printer.
