Subject: [THIN] Session Sharing FAIL


Hi List Legends,


I am hoping someone can point me where to look next.

We are having an issue with session sharing for Xen App 6.5 R01, on W2008 R2 



1) 1 server in the setup and in the load balancing (so its not a load balancing 

2) seems to only happen when the end users UPN (using the SAM login= no 

3) we run a multitenancy so the 'upn' use is imperative

4) we are using published apps only - NO desktop

5) all settings between the applications - audio, color depth and encryption 
are the same)

6) if the access gteway option was ticked session sharing would fail everytime 
- so its unticked at present on all published apps

More details:

I have tested by publishing apps direct to our single server (to eliminate any 
load balancing policies) – with still the same result.

I can pretty consistently replicate the problem with just Outlook and IE, 
however it occurs randomly with multiple applications

What I have noticed is that if I wait for the first application (Outlook) to 
launch and establish a session, then launch other apps (IE) within say 1 minute 
all session sharing works fine.

however if I launch the first app and let it establish a session then leave 
only this app open for 5min or longer, then launch the second app it will 
create a new session! Its as if after a session has been open for a while it 
then no longer allows some newly
 launched applications to share its session.

We have of course installed R01 (as there was a session sharing issue on that)

We have looked through the session sharing troubleshooting on the Citrix 
Website (http://support.citrix.com/article/CTX159159)

Please please please if anyone has other suggestions or where to look next - it 
would be MOST appreciated!
