    Are you running DeepFreeze? When we saw this, it was because we were using DeepFreeze for our lab computers and when AD would periodically change the machine account password, the machine would reboot and loose the password change, consequently have a different machine account password than what AD had assigned and could no longer authenticate with AD.
    To fix that issue, in our GPO's for machines that ran Deep Freeze we enabled Computer Configuration-Windows Settings-Security Settings-Local Policies-Security Options-Domain Member-"Disable Machine Account Password Changes"

    We've had a similar issue, it was caused by connecting an old machine with the same name and then renaming it.

    FYI, DO NOT implement this policy with the machines still frozen as they will immediately request a new machine password when this happens. Once they reboot, they'll revert to the old password and the machine account will be borked. Don't ask how I came to find this out.

    Logically I'd say yes, but you could argue there's no security risk leaving a domain, only joining a domain.

    Exclamation Did this get a definitive fix???

    Did anyone come up with a definitive network wide fix for this? Preferably one that I can understand too! As this is now happening here, and the cause would seem to be that laptops are not powered down properly, go into sleep mode when lid is shut, then the charger plug is turned off to the trolley and the laptop runs out of juice. I kept being told that folks couldn't log in on some laptops, then finding the laptop looking as if I forgot to add it to the domain. I cought one or two machines running Windows repair when I powered up plugged in. There are only 12 laptops to deal with, so if I have to edit registry on each, so be it, and I can do future edits before imaging. But help would be very much appreciated!

    Code:
     bcdedit /set {default} bootstatuspolicy ignoreallfailures
    will disable it and works as a startup script so

    Code:
    if exist c:\suroff.txt goto end
    bcdedit /set {default} bootstatuspolicy ignoreallfailures
    copy \\server\share\suroff.bat c:\suroff.txt 
    :end

    Thanks, but I'm going to need a bit more help. I've also found this which says it disables Startup Repair from running as default:

    Code:
    bcdedit /set {default} recoveryenabled No
    What's the difference? And is the second bit meant to be the startup script or a way of creating a startup script? Sorry, but I'm learning as I go along....

    the difference by the looks mine just stops it running automatically the other kills it so you cant run it manually either. yes the 2nd bti is a startup script so you can set it on a group of pcs and it will run once then not again

    Issues with domain membership after a system restore

    Disable System Restore. Start Up Repair is enabled on my staff computers, but System Restore is not and I've never had a problem with Windows 7 clients dropping off of the domain. The above MS article describes the issue. I wouldn't be surprised if Start Up Repair calls out System Restore.

    We finally found a way around it..

    Totally disable system protection and remove all of the backups.

    There is nothing for startup to attempt to repair to so the issue doesn't seem to happen.

    To disable the system protection this must be done whilst the machine is on a workgroup.


    I know if a machine dies, its a rebuild job..

    This 'SYSTEM PROTECTION'.... Is this just 'SYSTEM RESTORE' or is there more to it when 'START UP REPAIR' is also enabled, I have always disabled it on any computer I own or deploy here. Maybe it's just an urban myth now, but I shudder when I hear someone suggest using system restore, I always heard it doesn't fix anything, just takes up space and makes a mess of all your files and such...

    Does anyone use it and find it to be a good thing?

    I've always preferred the thought of doing a fresh, clean re-image than a SYSTEM RESTORE...
