Access Denied to C: as administrator

The sercurity settings for permissons were changed by another person using my
computer. They have denied all permissions as the administrator and i am now
unable to use or change any of the settings on my computer as access has been
denied to C Drive, is there a way to undo these settings to reset the
sercurity settings?

I am not an expert, first and foremost. But I think I can help you.
1.) you need to activate the Real Built-in Administrator. Click Vista Tutorials at the top of the page. First one on the list is How to Enable or Disable the Real Built-in Administrator Account by Shawn aka Brink. Once you have the real McCoy in the system, check all user accounts, remove the offending one, might have to change your own password in order to prevent that person to gain access to your computer again.
2.) change or reset the security settings : -
bring up the (OS) C drive, right click > click Properties > Security >Advance > Effective Permission > Select > enter ( your name )\administrators > click OK.
You should now regain full control of your computer. Please inform if it is successful or not. Good luck.

i can not do any of this as i have no access to anything! thanks anyways let
me know if you have any other ideas!

Sarah, can you click on the start menu ? If you can, then you can enable the Real Built-in Administrator. Here is how : _
1. Start menu > type cmd on the search box
2. cmd program will appear at the top of the panel, right click that
3. click Run As Administrator, press Continue when prompt
4.a black & white window appears, type the following ------------
net_user_administrator_/active:yes
( note that "_" represents a space before the next word )
5. press Enter key on your key board. The window will indicate if your request is successful or not. If not re-type the command and
watch for spacing. Don't use upper cast letters.
6. if it is successful, close the window. Logoff , and you will see an Administrator account next to your account and other user accts.( if any)
7. click on that new acct. and the system will start setting up the desk top for that new acct. When it's done, you now use it as I posted earlier
8. should you decide to remove the all powerful acct., just repeat the steps Except at step 4 type active:no instead of active:yes . Please let us know if it's ok this time. Good luck.
PS. Part of the reset settings procedures was missing , it got into a quote. Must have hit a wrong key. Trace back to my earlier post and include that quote as the continuation of the procedures.

Sarah, I hope you have not given up as you have not responded to my last post. Anyway, I actually have problem understanding what you mean by " I have no access to anythig ---". Are you unable to logon, and you're using someone's computer to post this question? Here is one more method :
1.) power off . Then power on and Immediately start tapping F8 key continuously until a black & white screen appears.
2.) use the up/ down arrow keys , stop at Safe Mode. Press Enter key.
3.) the built-in Administrator should appear. Click that ( no password is needed.) Now use it to remove user account(s), check yours as well in case it has been altered. Then go reset the permissions, etc. Good luck and don't forget to reply your progress.

right click on the drive,properties,security,advanced,then change the
settings to take full control of the disk

davejchuang,
I have the same issue as Sarah. I was working on trying to get two computers
networked and was changing and looking at OneCare parameters when I did
something that has resulted in not being able to access the c drive. Unlike
Sarah, I am able to boot the laptop to my desktop, but when I activate
windows explore it lists the c drive as "access denmnied" and will not let me
have access to the drive. However, I can run Outlook and it allows me access
to my email files which are stored on the c drive. However, I can not network
into the laptop which by the way is running Vista Business 32 bit. I have
also tried the recoomended actions you and others have indicated in this
tread. I was able to establish a new account via "net user administrator
/active:yes", but when I try to "change or reset the security settings : -
bring up the (OS) C drive, right click > click Properties > Security )\administrators > click OK." I get to the "Effective Permissions" tab and
it indicates:

Object name: c:\
to continue, you must be an administive user with permission to view this
object's security properties.
Do you want to continue?

I hit the "Contiue" button an receive the Windows Security dialog box
indicating "Can't open access control editor. Access is denied."

When I tried "bob's" suggestion to modify the registry to "Add "Take
Ownership" to right-click menu in Vista" I get an error message indicating
that there is an invalid registry command and thus have not been able to add
the Take Ownership function.

As such, I would apprecaite any help anyone can provide which will allow me
to regain access to the c drive.
Thanks,

Richard L. Miga

PS: I should point out that the sysytem still has some issues, but at least
I am able to backup the c drive prior to restoring the OS.

Once I was able to access the c drive again I then ran accross a number of
other challenges such as a "server execution failed" error message which was
preventing being able to network to the laptop on which the access to the c
drive was denied. Since I needed to network to this ailing laptop in order
tio retrieve some large files and significant environmental parameters I came
accross the following URL when I searched for information on how to address
the "server execution failed" challenge:

http://www.xoxideforums.com/networki...tml#post989337

I then followed the information provided and low and behold the ailing
laptop began to act like it did prior to my mistake which caused the denied
access to the c drive. The procedure provided at the above URL appears to
restore appropriate file protections.

I have included this information in this threead in order to assist those
who might have a similar problem as a result of tryi9ng to work with OneCare.

Hope This Is Of Value,
