Resolution

This error is caused because the configured user on SD Agent service is not an administrator or has less rights than the required. In order to solve the issue, the following command can be executed on the Agent:

"caf setcreds sdagent"

This will reset the user that SD Agent service uses to LOCAL SYSTEM.
