Citrix XenDesktop 7.6 and Machine Creation Services error

I have a Proof of Concept using XenDesktop 7.6.  I've created a masterimage and I'm trying to spin up a machine catalog using MCS.

It's errorring out with the following:

When I click to submit it to Citrix, it comes back that DCHP is not enabled.  DHCP is working perfectly and I've tested.  I can find nothing else on this error.

Anyone have any ideas?

Thanks

I've seen this before when the service account used by PVS has permissions assigned using the delegation tool.  This was in a 2008 R2 mixed mode domain.  

For some reason we had to give the service account full control to that OU where you have it defined to spin up new machine accounts.

On the DHCP, did you set the IP HELPER address on the segment where you are turning up the virtual machines?

Three, when using something like vCenter SDK and vSphere the account must have specific rights or assigned a ROLE in VMWare.  

Machine creation services uses the Hypervisor heavier than Provisioning Services.

It is failing during the image preparation phase.  

Do you have a visual on the hypervisor that is being used to see if the snapshot is created and new machines are added to the hypervisor?

What about AD?  

This is happening after the Connection to the HyperVisor so the assumption are permissions being correct and that is not always the case.  It can work 99% and be missing that 1% permission to finish up.

I've covered some of these issues here:

Also, your doing a private disk and separate?

Do you have more than one LUN presented to MCS in the Connection?  Did you choose to keep the VHDX and private disk on the same LUN?

Brian:

The service account we are using is spinning up VMs in other machine catalogs on the same controller.

All machines can pull IP addresses as we can create VMs manually and they pull IPs from DHCP.

The snapshot is creatd and the machine is created.  I can see the 80 gig disk in the new folder in vcenter.

On the pvdisk...there is only one LUN and the pvdisk is living in the same location as the vmdk.

Well.  On the others did you use PvD?  

Just curious if you updated the PvD before creating the image?
crp0499CEOAuthor Commented:
No, I didn't use PVD on the others.  This is my first attempt at MCS with PVD.  The Master image....I'm logged in now and when I tried to reboot it, it told me my PVD inventory needed to be updated before I could reboot.

I wonder if I uninstall the VDA on my master image and reinstall it without the PVD option if that will work?
Brian MurphySenior Information Technology ConsultantCommented:
Depends.  Are you Feature Release 3 for 7.6?

This added Windows 10 support but not necessarily for PvD.

My guess is, yes, if you create a new master image and no PvD it will work.

Brian, it has something to do with the PVD.  I created one without a PVD and it works great!

Thank you.  I'm going to go to 7.7
