We are in the process of building a new xenapp 5 farm to replace our old presentation 4 one. The new xenapp 5 farm has a problem when using the java 9.4 client that comes with our our external secure access appliance (Aventail) to connect to a desktop session. It connects ok and can be used but disconnects within a minute of inactivity. We still have the presentation server 4 farm and this does not have the disconnect problem when using the same java client on the appliance.
If the pc connecting to the appliance is windows xp the error on disconnect is "the Citrix Presentation Server is not available, please try again later"
If the pc connecting is windows 7 the error is "The connection failed: java.io.IOException This is probably due to network problems"
Connecting to the Xenapp 5 farm using the full client does not have this disconnect issue either.
Have followed lots of threads and support notes but have been unable to find the cause. Appreciate some help!
