The ability to share Windows files and folders over a network is essential when it comes to making the most of networked computers. Without the ability to do this, we wouldn’t be able to get things done in the office or even at home. Shared folders allow anyone using one computer to access files on a different computer. Of course you need permission to do that but that’s a whole other story!
In addition to the manual folder shares you set up, Windows has also included administrative shares. These shares are used to access files and other folders on a remote computer that are not shared manually on that remote computer but are hidden by default. So if you have administrative permissions on a remote computer and need access, let’s say C drive or any other drive on that computer, you can do that with this type of share. Keep in mind that administrative shares are not available in major versions of Windows.
To access these shares, you will need to type the UNC (universal naming convention) path just as you would with regular shares but you will use $ to tell Windows that you are accessing an administrative share. To access the C drive’s administrative share on a remote computer, you can use the UNC path for \\ ComputerName \ C $, but you can replace ComputerName with the actual name of your computer.
Depending on how your accounts are configured, you may be required to enter a username and password to access the admin share. Here you will enter the username and password of a user who has administrator access on this remote computer. Do not enter the username and password for the account you are using on your local computer unless it also has administrator access on the remote computer.
When typing your username, you will need to enter it in the format computer name / username. You can also use the IP address in place of the computer name if that works better for you or if you are having problems resolving the name.
Depending on the version and / or build of Windows, you may encounter issues accessing this administrative share as Microsoft has been trying to secure its operating systems more and more recently. If you still get an Access Denied message, there is a fix that includes a registry change that you can make on your computer to allow these admin posts to work properly.
On the computer you want to be able to access using admin shares, open the registry editor by typing regedit in the launch box or Cortana’s search box. Then you will need to go to:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Policies \ System.
Then right-click on any blank space and choose New> DWORD (32-bit) value and type LocalAccountTokenFilterPolicy exactly as shown.
Then you should end up with something similar to the image below.
Now you will need to edit the value of this new element that you just created. Just double-click on it, change the value data from 0 to 1, click OK, and restart your computer.
Now you should be able to access the administrative shares on this computer without any problems.
If you want a faster way to do this process, you can type the following data into the Run box and press Enter.
reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\system /v LocalAccountTokenFilterPolicy /t REG_DWORD /d 1 /f
