I don't know where it's stored in the windows machine.  So I can't help
you salvage the current situation.  But if you dust the vm's and start
over, you'll just run into the same thing again.

What you're fighting with the snapshots is the windows machine changes
the password every 7-30 days depending on the version & service pack.
So depending on the timing, a reverted snapshot won't work anymore.
Depending on the timing, every snapshot could have a different password.

You can disable machine password changing once the machine is joined and
functioning.  Join the machine and reboot to get the random password
change initiated by the system.  My dodgy memory says the original
password is the netbios name of the machine and is changed on reboot.

Key     = HLM\SYSTEM\CurrentControlSet\Services\NetLogon\Parameters
Value   = DisablePasswordChange REG_DWORD 1

There are some ms articles about this mainly dealing with replication
issues, but apply to machine password changing in general.

Off the cuff, here's one:
