I think the KB article is pretty self explanatory, basically after a user exits their last session on a XenApp server it keeps the session open for a determined period of time so that if the user reconnects within that time period they will utilize session sharing and their application will launch lightning quick… cool sh*t huh? basic…yes, works, yes.

Heads up if you use XenDesktop 5 or XenApp 6.
If you get the error “An error occurred while making the requested connection” when trying to connect through web interface running Xendesktop 5 or XenApp 6 the issue could be a Microsoft patch. We just ran into this issue with XenDesktop 5.
This is the patch http://support.microsoft.com/kb/2286198 that wreaks havoc.
Here is a forum article related to the issue http://forums.citrix.com/thread.jspa?threadID=271745&start=15&tstart=0

Figuring out why a pc or server is slow at logging on can be a long and difficult task. Userenvlog logging existing in Windows XP and 2003 and there is a new process for turning this on in Windows Vista, 7, 2008. This is a good step in the troubleshooting process to see if group policy could be slowing down the logon process. http://blogs.technet.com/b/mempson/archive/2010/01/10/userenvlog-for-windows-vista-2008-win7.aspx
Citrix Provisioning Server (PVS) is a powerful technology both for hosted virtual desktops and for ensuring consistency across a XenApp farm by using PVS to deliver XenApp. A common question in deploying PVS is whether it can be virtualized…and I think this article by Citrix does a great job of laying out the decision criteria we use in deciding whether it can be virtualized. I’m also happy to see that Citrix called out the lack of LACP support in XenServer…while XenServer is a capable hypervisor the lack of this feature almost always means that virtualizing PVS in a large production environment is out if XenServer is the hypervisor (and 10Gb is not in play).

There are quite a few methods to deliver applications and desktops to end users, in some cases multiple “correct” ways…this leads to some confusion. There also are some new products (delivery services 1.0) that exist but have some limitations today…all good things to pay attention to … or better yet, use Lewan to pay attention to for you.
