Titolo: Problemino da guinness dei primati...

Intendendo con primati le scimmie...
Nella mia università è successa una cosa da accapponare la pelle, una
ragazza entrando come admin, per paura che qualcuno potesse accedere
dall'esterno ai suoi files sul c:, ha rimosso tutte, e dico TUTTE!!!
le autorizzazioni da c:; morale della favola nessunoi riesce più ad
accedere al sistema...
E non si riesce neanche a ripristinare dal cd di installazione.
Visto la patata bollente è capitata a me c'è qualcuno che ha
suggerimenti sul da farsi????
Grazie in anticipo
Cristiano
P.S. i file gli ho bakuppati montando il disco su un altro pc e usando
ntfs reader per dos; comunque se ci sono idee su come ripristinare il
sistema fatemi sapere...

sistema fatemi sapere...
Puoi montare il disco aggiungendolo su un altro PC con installato NT e
modificare i permessi da li'?

Cannot Log On After User Access to Boot Partition Removed
The information in this article applies to:
Microsoft Windows NT Server 4.0
Microsoft Windows NT Workstation 4.0
This article was previously published under Q155315
SYMPTOMS
If you remove access for the Everyone group from a Windows NT File System
(NTFS) boot partition and click the Replace Permissions On Subdirectories
check box so that it is selected, you lose all access to the partition, even
if you are currently logged on as an administrator. You may also receive
error messages stating that your desktop is not accessible. In addition, no
other users can log on.
When the Everyone group does not have access to the partition, no user has
rights to make any change or log on to the system. If you attempt to log on,
Windows NT returns you to the logon screen.
If you restart Windows NT, you may receive the following error message on a
blue screen:
STOP: c000021A {Fatal System Error}
After you log on, you may receive the following error messages:
Limited Virtual Memory:
Your system is running without a properly sized paging file. Please use the
Virtual Memory option of the System applet in the Control Panel to create a
paging file, or to increase the initial size of your paging file.
Desktop:
Can't access this folder. The path is too long
NOTE: You do not receive any warning that removing the Everyone group
removes all users, including administrators, and you are not warned that
some system-wide functions may no longer work.
CAUSE
Removing the Everyone group and selecting the Replace Permissions On
Subdirectories check box removes all users, including administrators, and
prevents anyone from accessing the partition.
RESOLUTION
To resolve this issue and allow users to log on after this problem has
occurred, use any of the following methods:
Method 1
Set up Windows NT on another partition or hard disk in the computer, using
the following steps:
Set up Windows NT on another partition or hard disk.
Log on to the new installation of Windows NT as an administrator.
Take ownership of the original partition.
You should be able to gain access to the data files on the original
partition.
Method 2
Reformat the partition and reinstall Windows NT using the following steps:
Reformat the hard disk partition on which Windows NT is installed.
Reinstall Windows NT, and then restore any data files from a backup.
Method 3
Use File Manager to change the permissions. To do so, follow these steps:
Log on to the computer using an account with administrator privileges.
Press CTRL+ALT+DELETE, and then click Task Manager.
On the File menu, click New Task(Run).
In the Open box, type "winfile" (without quotation marks), and then press
ENTER.
Click the boot drive, and then click Permissions on the Security menu.
Grant the Everyone group Change permissions.
Close File Manager, and then restart your computer.
MORE INFORMATION
To prevent the Everyone group from having explicit rights to the partition
without preventing access by any user, use the following steps:
Grant the user who is currently logged on, or a group that contains the user
currently logged on, proper access to the partition. For example, the
Administrators group should be granted Full Control permissions.
Grant the System group Full Rights.
Remove the Everyone group.
Click the Replace Permissions On Subdirectories check box so that it is
selected.
Click OK.
NOTE: Granting the System and Owner groups full access to the partition
after removing the Everyone group does not allow the default user ID, or
administrator, permissions to log on and access files even though it is
considered an owner. To grant permissions to the Administrators group, you
must explicitly add the Administrators group.
The user attempting to log on must have sufficient permissions granted
before logging on. The minimum permissions necessary to log on (assuming the
System group has full control of the volume root and all system directories
and files) are:
   %SystemRoot%:                               Everyone - READ
   %SystemRoot%\System32:                      Everyone - READ/EXECUTE
   %SystemRoot%\System32\Repl\Import\Scripts:  Everyone - READ/EXECUTE
   (if users have logon scripts)
Depending on your environment, additional permissions may be necessary.
