It is a File Server I am wanting to have HA. So no applications to start.

OK, if it's like that, then it should work. If Replistor is installed on the virtual node, and one physical node failover to another, then the virtual node doesn't change, so it's not a Replistor fail over, and it could replicate data to other machine without problem

fleabag, take a look in the Replistor server configuration, you will find the "alias" tab. That is used precisely for what you are interested in, you can set up an server alias that will fail over to the target machine, making sure that the same data is available over the configured alias.
