Need help in restoring default permissions of system on specific Drive

Hi all,

I had a bit of a network security breach earlier today. And decided later to fiddle around with the security permissions of my drives in a attempt to reduce the risks to my system.

Then I made a huge mistake that I only realised afterwords, "naturally",...

I had set the drives system permissions to not allow any changes to be made to the drive or its permissions...!

Now I am quite stuck with my finger up somewhere since I do not find any way to restore the permissions to default and I have no backup to restore to. I have attempted the suggested cmd method of,

secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose

But does not get all of the database entries restored, I have gone to administrator and accessed the regedit to no avail.

Please help I did see another thread where the following batch file was given to fix a similar problem but it gives me an error.

Bat file unlock:

@echo off
:FRM
cls

title File/Folder Restriction Menu
echo Folder Restriction Menu
echo.
echo Please Enter Access Level...
echo.
set /p a=Enter Path Of File/Folder:
echo.
set /p b=User Name:
set /p c=Permission Type:
echo.
echo.
echo.
if %c%==deny goto lock
if %c%==grant goto unlock
if %a%==menu goto start2
if %b%==menu goto start2
if %c%==menu goto start2
:lock
cacls %a% /e /d %b%
cls
goto start2
pause
exit
:unlock
cacls %a% /e /g %b%:f
cls
goto start2
pause

Error:
"The system cannot find the batch label specified - start2"

Please help if anyone has some advice on maybe fixing this problem?

Maybe this helps: i accidentally removed permission for 'authenticated users', and now getting error "access is denied" for my D drive, Then what i did and worked: My computer->right click on D drive- Properties-Security-add/edit and type Authenticated users , ok , all restored..
