When using a least privileged user account to run a backup as described in the user guide, the backup operation fails with the error:
"Cannot access the Admin$ share on the target computer. Make sure the Admin$ share is accessible and try again."
The backup agents are installed and show up in console.
If you know the Forest Recovery Agent is already installed, uncheck the "Ensure Forest Recovery Agent is deployed":
If the Forest Recovery Agent has not been installed, install it manually from the RMAD setup files.
