Environment

CItrix XenApp Server 6.5

Cause

• The XenApp probe requires the "Citrix XenApp Commands Remoting" service to be running on the Citrix XenApp Server.
• This service tries to download the certification revocation list from Microsoft and if it does not succeed in a timely manner it will not start.
• If the XenApp server does not have internet access then this service will never start

Resolution

1. Enable internet access on the XenApp Server
   
   OR
   
   
2. Create a file called "Citrix.XenApp.Commands.Remoting.Service.exe.config" with the following contents: 
   
   <?xml version="1.0" encoding="utf-8"?> 
   <configuration> 
   <runtime> 
   <generatePublisherEvidence enabled="false" /> 
   </runtime> 
   </configuration> 
   
   Copy this file into: "C:\Program Files\Citrix\XenApp Commands" (assumes default install path)
   Restart the "Citrix XenApp Commands Remoting" service
