AD Domain Login Fails when the Computer's Snapshot is Reverted to a Point in the Past

Currently Being Moderated
This issue occurs because the machine account password changes automatically every 30 days when a computer is joined to a Windows domain. When the computer's snapshot is reverted to a point in the past, the password in the virtual machine does not match the version on the domain. When the passwords do not match the domain cannot authenticate the machine's system account credentials nor any user logins from that machine.

To ensure domain logins are successful:

  • Restart the virtual machine.

  • Join the virtual machine back to the Windows domain.

  • Restart the virtual machine.

 

Note: To prevent this issue from happening, disable machine account password updates. For more information, see How to disable automatic machine account password changes .

This describes my issue exactly but I can't figure out how to "remove the virtual machine from the Windows domain" and then "join".

Does this mean I need to delete the VM from my library and then add it again?

Or, do I try to remember what my password was 4 months ago so I can login to the computer (but not the domain)?

Found no results in my searches for further explanation. Please help and thanks much!

Hi Peg,

 

What the KB article means is that you need to log into the Windows VM that is having the machine account problem (use the machine local Admin account), dis-join the machine from the AD Domain (put it into any workgroup), reboot, and join the machine back to the AD Domain.

PS This KB article is only good for solving the automatic machine account password change when you reverted a snapshot to a point in the past for a Windows VM that is part of an AD Domain
