One of the users on a Windows 2000 Pro machine was given Administrator privileges and he set the permissions for the whole C drive to read-only for the Everyone account.
The drive is NTFS.
Now none of the accounts, including the Administrator account can log in, the machine just goes into endless reboots, just before the password prompt would normally appear.
What can I do to make this drive bootable, short of wiping it and starting over? Is there a utility that would allow me to reset the permissions from a CD bootup or floppy? I have the passwords for all the accounts on the machine, so that's not an issue.
I know that Partition Magic would reformat the drive to FAT or FAT32, but would that solve my permissions problem?
