Desperate..Plz Help..Admin Access Denied

Hello everyone....

please can anyone help me urgently....

i have win 7 home premium 64bit.....n while trying to change the security options for other users, (deny access to them), i also did it for another user who is also an admin like me..... and now i cant access my folder in my d drive....

every time i open it i get a dialog box saying
you have been denied access to the folder - to gain access use security tab....

so i go to the security tab, press edit, and the administrators got a tick next to allow but it is all greyed out so i cant untick/tick anything.


i do the same thing as another admin user but this time i can go to adding a user to have permission by pressing the advance tab and selecting the user but when i press ok and go into the same problem arises.



anyone please please please help me.....im desperate as this d drive has all my work in it.....

I'd give either cacls or Icacls a try. Just make sure you open the command prompt as an administrator.

Try using a system restore point.
