Unable to Launch your application. Cannot connect to the Citrix XenApp Server.
We have one Citrix server 20 user licenses. We use Presentation Server to administer our Citrix enviroment. Version 5.2.
Internally and Externally - all users are able to login to the client and get the desktop. But when they click on an application - like WORD - the following message comes up:
Unable to launch your application. Contact your help desk with the following information: Cannot connect to the Ctrix XenApp Server. There is no Citrix XenApp server configured on the specified address.
We just installed this new version on our server - we uninstalled our previous version and installed this one rather than upgrading. All worked for a while possibly 2 hours (?) then this started happening. First to internal users and now external users are getting the same message.
I have looked in all the Citrix logs and Event Viewer - no errors.
Does anyone know what could be our problem here?

ASKER
We are providing a published desktop with published applications. They are going through a web interface (https:) to get their Citrix desktop. I upgraded to the latest ICA webclient but that did not help.
I tried removing Word and publishing it again but get the same results.
I really appreciate your help.

Just to provide the less Citrix savvy people like me with a little more detail -
In the Citrix Access Management Console and then within Citrix Resources > Configuration Tools > Web Interface you will find your settings for your internal site and external site.
My problem was that Citrix worked internally but not externally and I was getting the error message in the original post.
I right clicked on the External Site and chose 'Manage Secure Client Access' and then the 'Edit the DMZ' subsection. The client IP address was left as Default like it should be but the 'Access Method' was set to direct instead of Gateway Direct.
As soon as that option was changed it started working again. Not entirely sure why it changed in the first place but thats life!

Are your internal users going through Web Interface or XenApp Services client?
Have you tried removing one of the offending applications (i.e. Word) and re-publishing?
