issue maintenance + power off machines- solution

I will describe a problem encountered some time ago regarding finding large numbers of vms in maintenance enabled and powered off.

 1

 

That issue  was happening after the power management kicked in over the night. After some reboot fails of the problematic machines-  all remained in unregistered state. I left them in maintenance and off.I powered on one from the hypervisor  console and tried to authenticate with a domain user ….  the trust relation ship between machine and the domain was broken…

From the PVS console i made a reset for the password computer account

2And the machine registered no problem

I continued to search for various accounts with similar issues  and reset when i reset the account of one of the machine i got the following error message

I dig on the Active Directory and seems that some accounts from the VDI OU are not longer managed by the account that was supposed to do that.   I reinforced the user to have full control again on the objects from the VDI container

I also checked the domain GPO for the account password  changed policy  to be enabled

5

 I  reseted  the machines account password for affected vms  and all came back to normal.
