Hi
There are different levels of administrator.
The uber administrator account can be accessed through the administrator command window by this process...
How to Enable the Administrator Account
Open the command prompt with elevated privileges by clicking the Start orb, All Programs, Accessories, right-click Command Prompt and then select Run as administrator.
Type or cut and paste…
net user administrator /active:yes
and then press Enter.
Log out and log back in as Administrator.
When you are done undue the process by doing the same thing and pasting in
net user administrator /active:no
The other option is to use "Take Ownership" to allow access to individual files...
