Access Denied to C: as administrator


S

Sarah

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?

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
Advance > Effective Permission > Select > enter ( your name
)\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

After posting my message for help, I did a search over all the Vista Forums
instead of just the security for8um and found the following:

http://windowshelp.microsoft.com/communities/newsgroups/en-us/default.mspx?query=how+to+regain+access+to+c+drive&dg=&cat=&lang=en&cr=US&pt=&catlist=D1CBF0BD-E8EE-4D73-8ECC-15AF7EC6783B&dglist=&ptlist=&exp=&sloc=en-us

To make a long story short, I followed the instructions given in the post at
the above URL and I WAS ABLE TO GAIN ACCRESS TO MY DRIVE. For purposes of
completness in one location the proceddure is copied below:

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/networking/76388-vista-giving-you-server-2.html#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,

Richard L. Miga

I denied access to my drive C: under the Security Tab in properties and after i reboot the system, i couldn't do anything on the system again. If i try to copy it gives access denied, even i can't open any folder because it'll give "Windows Explorer is restarting" after which will return to desktop.

I also try to click on MY COMPUTER, it says the same thing but i cancelled it and it displays a code:
upload_2017-4-22_12-17-18.png


if i click okay it will display the normal my computer Box... but each time i tried to access the property to change the Security access it gives:
upload_2017-4-22_12-20-7.png


and i tried to change the ownership, it gives this
upload_2017-4-22_12-21-4.png


and also this when i click on edit:
upload_2017-4-22_12-21-46.png


PLEASE WHAT CAN I DO
i need urgent solution.
Thanks
