Userenvlog
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
Virtualizing Citrix Provisioning Server
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).

Citrix Receiver and plug-ins can create some confusion
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.

How-To Make XPe a View Appliance
Background:
I had a need recently to modify the behavior of a Windows XPe (embedded) device to act as a VMware View Appliance. The goal was to end up with a device which would boot and launch the View Client connect to the View Manager and challenge the user for their ID/Password. Then connect to a specific virtual desktop.
Some devices have a wizard for configuring exactly this behavior, however the device I’m working with seems to have no such feature.
This is just a little diferent from the ‘kiosk mode’ feature of View in that the View Client does challenge the user for their credentials rather than having the login credentials stored/passed to it.
Note, a variation on this idea could be used to make a repurposed desktop act as an appliance for either View or XenDesktop.
This could also be made a little prettier by using a .vbs script and wscript rather than the .bat file and cmd.exe.
Solution:
1.) Disable File write filter
2.) Write batch/cmd file which launches View Client with appropriate parameters in a loop (points to VMware – View client accepts USB pass-through and desktop to launch from the command line).
3.) Modify for the auto-login user – hkcuSoftwareMicrosoftWindows NTCurrentVersionWinLogonShell to launch the batch/cmd file. You can do this using the ‘load hive’ feature of regedit running as the admin user.
4.) Logout as admin, let the auto-login login as user – test, test, test.
5.) Modify CMD launch properties to minimize the cmd window size.
6.) Kill the CMD process
7.) Logout of ‘user’ session (ctrl-alt-del)
8.) Enable File write filter
End result:
When the user logs in explorer.exe is never launched, and the view client presents it’s login challenge. When the view session terminates the .bat file re-launches the view client … forever.
