SUMMARY
SQL error while ReliableDR is being installed
ISSUE
This error can occur during ReliableDR installation. SQL Express is installed as part of the installation, and it creates a user with a hardcoded password that ReliableDR uses to access the database. The password is created with a length of twelve characters. If you have a Group Policy (GPO) that forces Windows servers to use passwords longer than twelve characters, ReliableDR installation will fail with the above error message.
You can resolve the problem by removing the server that will run ReliableDR from the domain and changing the server’s policy to allow passwords with twelve characters.
