There should be events in the log before the one you give (probably within the first minute after the VM restarts) that might be more helpful. However, if you can’t find anything then there’s an alternative way of configuring the VM which might help. On the desktop VM, create the registry key below (a string, REG_SZ) and set its value to the FQDN of your XenDesktop controller (DDC): HKLM\Software\Citrix\VirtualDesktopAgent\ListOfDDCs (on a 64-bit VM you need “HKLM\Software\Wow6432Node\Citrix\VirtualDesktopAgent\ListOfDDCs”) Now reboot the VM and see if it registers. In this mode you will certainly find event log messages from the Citrix Desktop Service that show the list of known DDCs (just one here), their names, which one the VM is attempting to register with, and the result of that registration. This is a perfectly valid way of configuring the desktop VM and is what you would have obtained had you not used Quick Deploy to install the VM.

Try this.

SmartAuditor Issues
The SmartAuditor Player might fail to correctly display sessions launched with Citrix Receiver for Windows 3.0, instead showing a black screen in the Player window. To prevent this, disable the gradient fill feature on the XenApp server hosting the sessions by creating this DWORD registry on the server and setting its value to 1: HKLM\SOFTWARE\Citrix\Ica\Thinwire\DisableGdiPlusSupport.
