We have a PS4.5 farm comprising of 48 identical W2K3 servers running published apps.
Our users launch IE as a published app and then connect to an external Citrix farm hosted by a 3rd party company via a Citrix Web Portal.
This external farm is also PS4.5 and comprises of 10 W2K3 servers running a published desktop.
The users can navigate to the portal, enter their credentials, log on and see their application set with no problems. However when they try to launch the published desktop they intermittently get the following error message:-
'Cannot connect to the Citrix Presentation Server. Could not find specified Citrix Presentation Server.'
From our investigation here we have noted that:-
The published desktop launches ok on all 10 servers at the 3rd party end.
It is always the same servers (at our end) that our users are connecting from when they get the error message.
The Launch.ica file shows no real difference between a server that can connect and one that can't.
There is nothing in the event logs at our end to suggest why the connection is failing.
We are a bit stuck with this one now, out of our 48 servers 22 of them connect every time with no problems and 26 get the error.
Has anyone seen something similar to this or have any ideas how to resolve it?
