Permissions removed from domain controler, how to fix

I have a problem where a windows 2000 domain controller has had its hard
disk permissions changed.
By default everyone has full access to files on c drive.
Someone has changed this believing that it was a security risk. He removed
everyone permissions and gave administrators full control, and users read
and execute.

At next reboot the domain controller would not function, it gives a error I
can not remember at the moment, but to do with security and asks you to
reboot in directory restore mode. You can not log in and they have forgotten
the system restore password or it is not accepting it.

My guess is that the system can not access files it needs. What I want to do
is reset the permissions on the disk.

Is there any way to do this?

Hi ThatsIT.net.au,

Are you able to login using Last Known Good Config, or Safe Mode? If Last
Known Good Config does not work but you are able to get into your system
using Safe Mode, you can use one of these methods..
http://www.petri.co.il/change_recovery_console_password.htm to change you
recovery console/directory restore password.

Now is a good time to review your backup policy.

we have backups.

but we could not get into machine to restore them. could not even repair as
it would not copy files onto disk.
A staff member changed permissions on cdrive, removed everybody group, I
assume this had something to do with it
 
Re: Permissions removed from domain controler, how to fix

I have seen many networks which have succesfully removed the Everyone group
from the root without issue, however it was done carefully ensuring that any
services using Anonymous login were accounted for as well as adding the
Authenticated Users group in place of Everyone. FYI - Its not recommended
to do this on an Exchange server as it needs Anonymous login for a number of
processes. I would suggest that before one removes the everyone group from
a server, that some research be done with regards to the functional role of
the server and the possible impact of this change.

Winternals ERP Commander would have been the perfect tool for you (and
should be in everyone's toolkit) unfortunately Microsoft bought them and has
yet to release their own version yet. (I still have my copy though, Yay!
lol) If you can get a copy from someone though i can't even tell you how
much aggrevation it will save you.

A backup facility is only as good as the subsequent restore
process. If you are unable to restore the System State then
I suspect that your backup was never been tested and that
its usefulness is limited. There are several third-party products
that let you restore anything, regardless of the state of your
machine, Acronis being one of them.

I think what he did was remove everyone from the c drive and replaced it
with users read and administrators full.

any how could not write to disk at all, could not even reinstall leaving
file system in tact

The system state is fine, all the backs ups are in tact

But we can not log on or copy anything to disk, not in safe mode not in
directory restore mode not in recovery mode.

in recovery mode the console will accept one character then keyboard will
not work
