Citrix WI + CSG - Initial delay when loading

Finally took some time today to figure this out.  I had always wondered why there was a delay upon the first page load after IIS resets.  Turns out Citrix had a KB for it.

Appended this to my aspnet.config and no more issues.

ICA sessions - TransparentKeyPassthrough

By default, Windows hotkeys like alt+tab are only passed through the ICA session when in full screen mode.  In my case I have a Citrix published desktop with a static resolution that launches in windowed mode.  When the published desktop is my active screen, hotkeys apply to my local machine.  In order to have it apply to my session, I had to set the following registry values on my client machine to "Remote".

My Client OS - Windows 8 x64
Citrix Receiver -  v3.3.0.17207

1.  Change auto-protect to scan when file is modified.

 

2.  Exclude pagefile, Citrix program directories, and print spool folder.



3.  Preventing SmcGui from launching in each user's terminal session.  This should improve performance and could help with Symantec licensing if you are not licensed per user.

• Open regedit
• Browse to HKLM\SOFTWARE\Symantec\Symantec Endpoint Protection\SMC
• LaunchSmcGui change from 1 to 0

If you receive this error - Cannot edit LaunchSMCGui:  Error writing the value's new contents.  You must disable tamper protection via Change Settings > Client Management menu.



Uncheck then go back and make the change to LaunchSMCGui



Done!
