Dear experts,

Once again i have a strange problem witch i can not solve by myself. We use Citrix XenApp 6.5, and my user complain about the time between clicking on the application and the system actualy lanching the application. The time betwee those is about 10 minutes.

The user profiles loads within max 30 seconds, so it seems there is no problem there. The users see the loading screen. When the loading screen says "Launching application" the screen disappears. they wait for 10 minutes and the application launches.

When i give them the opportunity to logon to the desktop and start the application, the application starts imidiatly.




We have 5 citrix servers, witch are alle the same and all have the same symptoms. our citrix servers run vmware and virtualised windows server 2008 r2. Every server has an average of 10 users.

Have you looked at application streaming instead , when we looked at launching applications instead of using published desktops we noted it was loading the users profile for each application hence slow startup times for applications.

Have you installed all hotfix updates on the servers? What kind of profiles are you using? Are they roaming or something more advanced like Citrix profiles.

If the user RDP's directly into a xenapp server and launches the application, how long does it take to launch?

The servers are up-to-date and we only installed 1 hotfix "XA650W2K8R2X64R01". We use roaming profiles, and when users RDP directly the application takes max 2 seconds to start.

Does Powershell have you tied up in knots?

if possible create a OU move one citrix citrix server, disable policies and try it, id works fine then apply one one, so that it will be easy to find the which policy having issue.
