Hi,

I believe you want to access AWS FSX from the Windows EC2 machine that are not joined to the domain. It is not possible to access AWS FSX as machines need to be domain joined in order to access files systems[1]. The AWS FSX has to be mounted to your Windows EC2 machine joined to your domain[2].
