Terminal Server & XenApp Tuning TipsBy Pierre Marmignon @ 7:46 PM :: 19478 Views :: 8 Comments :: :: XenApp, Tuning, Terminal Server, Tech Tips
Working in SBC environments for some years now I've used some best practices documents like the well known Methodology In a Box (MIAB) from Douglas Brown or the MF Tuning Tips from Rick Delingher.
These documents, although really pertinent, are now quite outdated and do not include the latest OS and XenApp releases.
The purpose of this article is an attempt to summarize all Tuning Tips I've found (and also that I'm using) and describe the target operating system / XenApp version(s) they're working for.
Do not hesitate to give us your comments for this Article to be updated with your experience and feedback.
Please note that these informations are provided "as is" and that using these tips is at your own risks.
Please also Note that all REG_DWORD values are provided in decimal format.
All Registry Hives are provided for x86 platforms. For x64 Platforms, do not forget to add "WoW6432Node" if hive is in HKLM\Software.

Along with these registry settings, do not forget to install UPHClean (W2K / W2K3) to manage profiles at logoff and ensure no lock will remain leading to profiles corruption and long logoff times.
UPHClean is natively embedded into Windows 2008 and later (User Profile Service).
Also, as a Best Practice, it is recommended to Disable Data Execution Prevention on Windows 2003 and Windows 2008.
To do so, you have to modify the boot.ini file or use one of the following command line(s)
For Windows 2003 : bootcfg.exe /raw /fastdetect /noexecute=AlwaysOff /ID 1 For Windows 2008 : bcdedit.exe /set {current} nx AlwaysOff

# bsorensonFriday, July 24, 2009 8:37 PMWe just saw an instance where a .NET application, Peachtree 2009 and 2010 would NOT load screens due to the CursorBlinkRate being changed. It took us over 100 hours of time with more then 40 hours on the phone with Peachtree to narrow it down and find it. Setting it breaks the Peachtree application and it's related to those screens being written in .NET.
Just posting this as many of our optimizations came from this site for our Terminal Server environment. Beware!
Thanks,Bill [email protected]

Sorry for the side effects you've encountered.
I've never seen such a problem with the Cursor Blink Rate being modified in years of use.
Thanks for your feedback.
Best Regards,
Pierre
# SamWednesday, August 12, 2009 12:31 PMi remember that there was a guy who made an adm template with these settings so u can enforce them via gpo , is that still available ? and did he updated it ?
# Pierre MarmignonWednesday, August 12, 2009 12:37 PMHi,
Yes there is an adm with these settings. You can find it on The XenApp Blog

The Admx file is available at Ervik.as
# FDTuesday, September 01, 2009 11:10 AMHi Pierre,I remeber from the old Methodology in a Box from DABCC that the HKLM\SYSTEM\CurrentControlSet\Control\PriorityControl Win32PrioritySeparation should be set to backgroung process (value of 24) rather than foregroung (value of 38) because of the way sessions are managed. would it be possible to investigate a little more on that settings? BTW it is possible to change that setting via Start -> Settings -> Control Panel -> System -> Advanced Tab -> Performance Options-> Set Application response to ‘Background services’
Regards,FD
# Pierre MarmignonTuesday, September 01, 2009 5:16 PMDear FD, Yes you're right !
I've always set it to optimize "For applications" (even if other articles were saying to set it to "Background Services") because even it's not a "ideal" setting for Terminal Server / XenApp Servers it boosts the CPU Scheduling.
However, for some XenApp requirements, you could have to set it back to "BackGround Services".
You can read this nice article about it from Jeremy Saunder's about it !
Best Regards,
Pierre

Thanks for this post.
For me HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer\VisualEffects
doesn't work.(option box doesnt changed in advanced settings)
But I try in HKCU, and here it works fine. (option box are well Displayed in advanced settongs)
Do you think it's just the display or settings are in HKCU ?
Bye
Vincent
