Whenever I try to open an application from the PNA I get the error message "the remote server failed to execute the application launch request". How do I overcome this?

I also get a simialr message in the WI too.  I tried checking the permissions on the file and the user and administrator were in there.  There is no encrptyion set either.
I cannot really understand because it worked this morning and I have not changed anything.  There is only one computer connected to the server so I know its not a bandwidth or resource issue.

Is this the only citrix server in the farm?  I have seen some issues where it could be xml settings or if you have an application such as office where the .exe files can be stored in different locations because servers have Office 10 on one citrix server and then Office 11 on another.

Does this error happen for every application or just one app?
