I am currently facing problem in accessing my local drive in windows vista. Is anyone here to assist me to modify the permissions and grant rights to local drive D. I have revoked from permissions to local disk D in Windows Vista operating system, and at the present I am not able to modify permissions or have ownership as Administrator. I tried to restore my OS to earlier well condition even this did not work. I also tried to change it from security it show that unable to establish ownership.It shows that Access denied. If anyone ever faced this kind of problem and got the solution please let me know.
