Hello everyone, I have two computers, both running windows 7 (one is 64bit and the other one is 32bit) connected via LAN and also via wifi. One of them has the entire local drive shared with full allowance to everyone (full control). I decided to remove those permissions and set full control to "deny". Then, I had to cancel the task and decided to resume later. WRONG, now I lost access to that drive, even though I can access some files. When I try to get into the drive, an error message pops up saying " C: is not accesible. Access is denied. I made some research and it seems to be a common problem, but every step I followed didn't work. It shows as 0 bytes and security options shows nothing but "You don't have permission to view or edit this object's permission settings". I've tried taking ownership, even in safe mode and as administrator, not to avail. It keeps saying "access denied" I also tried setting a hidden administrator account, but account manager is "not available for my system" When I did those unfortunate changes, it was not from that computer but from the other one, I think it might be the reason. Now I can't access my local drive nor change anything. Please, help me, I can't find a solution to this mess!!
I hope you have a good backup. NTFS "deny" trumps all other permissions. It's unlikely you will be able to use Windows to gain access to your drive. You can however use a Linux LiveDVD (such as Ubuntu) to gain access to the files on the drive so that you can back them up before rebuilding your system (Linux ignores NTFS permissions).
+1 ^, you set permissions without knowing or realizing what you were doing exactly. It's an issue that often happens with virus, but you did it yourself willingly. If you think about it, what you did would have the exact results that you are seeing. You set "Deny" access to Everyone, so Everyone is denied access to the files. It has nothing to do with the fact that you changed things from another computer, the system is acting exactly how you told it to act, which is to deny access the files.
You can try to do a Repair setup of Windows, but I am not fully sure if that will reset the rights on the files you changed.
Thanks for your replies, I'll try to access via Ubuntu and save the majority of files and then start all over with a fresh new windows install. I wonder if a linux based system mounted on a usb drive will recognise my hard drive. BTW, which of them would you recommend? I used puppy linux once and seemed very reliable to me
