XenDesktop 5.x – Desktop Director Web Page Loading Delay
I recommend that all that implement Citrix XenDesktop 5.x implement this fix to get a better performance when using Desktop Director.
Symptoms
The first Desktop Director user to log on, after IIS restarts, experiences a delay of over one to two minutes before the initial Desktop Director web page loads.
Cause
This issue is caused by a CRL check sent to Verisign.
Workaround
You can disable signature verification to prevent the loading delays by completing the following tasks:
- Check IIS for the ASP.net version that is in use with the Desktop Director site.
- Open Aspnet.config for editing in the following directory:
C:\WINDOWS\Microsoft.NET\Framework64\v2.0.50727Note
: The ASPNET.CONFIG file is located in Framework Directory for the version of the Framework you are using. For example, for a 64-bit ASP.NET application it is:
c:\Windows\Microsoft.NET\Framework64\v2.0.50727For a 32-bit application it is:
c:\Windows\Microsoft.NET\Framework\v2.0.50727
- Add the following lines to your Aspnet.config file:
<?xml version=”1.0″ encoding=”utf-8″?>
<configuration>
<runtime>
<generatePublisherEvidence enabled=”false”/>
</runtime>
</configuration>
