Hi, I really hpe someone can shed some light here....

I have 4 master VMs, and they're all displaying the same behaviour. Up till now everything has been fine, with no issues. We're working on Windows 10 1809. Horizon 7. VSphere.

What's happening is this... I can create desktop pools with any snapshot I took previously. i.e. up to a few days ago. So there's no problem with account permisions, rights, etc. That all still works. What I can't do, is fire up one of those VMs, make a change, shut it down and snapshot it, and then create a NEW pool from that snapshot. What I get is 'UNKNOWN ERROR: FATAL Customization appears to not have suceeded'. Which is strange as we aren't using any customization?

One thing that has changed is that when I turn the master VMs on they report that the trust relationship has failed. Now I've looked into this and I've been in and changed the reg key to stop the password change. I've also done the dance of removing/re-adding the machine to the domain. I've also tried resetting the computer account in AD. I even tried removing the computer account, before re-adding it to the domain. Nothing seems to satisfy the Horizon. It flat-out refuses to create any new pools from a new snapshot, but will quite happily build pools from the existing one (i.e. the very same snapshots that report they've fallen off the domain when I turn them on!).

Can anyone help with this? Please let me know if there's more information I can give.

Thanks!
