Enabling Admin Share on Managed Devices

  • Last updated on

Admin shares are Windows defaults that provide access to every hard drive partition on a system. Barracuda RMM automation requires the Admin share to be available to push files needed for automation. Older versions of Windows may have these shares enabled by default, but on modern versions they are disabled.

See the instructions for each operating system.

If the Admin share is still inaccessible after making the registry key change and restarting the system, run the Windows Prep Utility found in the Service Center under Site Management > Sites > {Site}. Resources can be downloaded and executed to automatically enable the Admin share along with any other prerequisites for monitoring and management.

Admin share access can be tested by logging into the Onsite Manager as MWService (or service account you have configured for the onsite manager to manage devices) and navigating in Windows Explorer to \\DEVICENAME\admin$ if you can reach the device, try again but this time with device IP, if the IP fails, reboot the end computer and try again, the OM has to be able to access the admin share by both IP and name of the computer, if rebooting does not work, reboot the Onsite Manager.
