Can't Restart Instant Clone - Fails to Startup

[DASIEric]

I have a eval environment that I am testing. I'm using a Eval of Windows 10 as well. I've done a Windows 10 install and installed the proper Horizon agents. I have a new installation of Active Directory with very little customization done to it that Horizon and the Instant Clones use. When I create an instant clone desktop pool, the clones will create and startup and show provisioned. I'm able to log into them with out issue. As soon as I reboot any of them, I see the clone go into maintenance mode and then back into provisioning mode as it starts back up. At some point, it does look like its back up and running but then it shuts down. Horizon shows the machine as "Error" with the warning: "Resync of VM has failed: Fault type is SERVER_FAULT_FATAL - Runtime error: We only support DvsPortGroup and OpaqueNetwork as the target network for instant clones". If I remove the desktop with the error, Horizon will delete the machine and recreate it and it will startup and work correctly. If I manually startup the VM from VSphere, I'm able to use the direct Horizon connection to access the VM and when I try to log in it says the "The trust relationship between this workstation and the primary domain failed".

Any suggestions on what I can do to make this work?

Can you let us know the type of network selected for this instant clone pool deployment ? Standard switch\ DV Switch\NSX-t network.

Also, please share the version information of Horizon View, Horizon agent & vCenter.

Thanks for your response. VMware best practice for instant clone is to configure distributed virtual switches in the vSphere environment & It is mandatory to configure distributed virtual switches in the vSphere environment for dedicated instant clones.

Thank you! Creating the Distributed Switch and assigning it to the master VM corrected the issue I was having with the instant clones.
