In using a server there is usually no user account logged on to the server directly , however we have to provide the domain name of the domain to which the server belongs and also the login credentials to log into the server.
In a normal PC or laptop, there is always an account logged on for the computer to function. In the case of this Backup program there must be an Administrator account logged on – it may be locked out. It's important that when installing and setting up the schedule, the person logged on has Administrative Access.
