The WhosOn Administrator can connect to a remote WhosOn Server. When you start the WhosOn Administrator, the Login form appears:

In the Server Name or IP Address entry enter the IP address or DNS name of the remote WhosOn Server that you want to connect to.

The User Name & Password can either be the global user name/password (as defined in the program Options - Remote Access tab) or one of your Named Users that has Admin rights.

Once connected you can manage the server as you would a local server - with the exception that you cannot create & edit Charts & Reports. You can create/edit/delete monitored sites and users, and you can change the program options. You can Stop the WhosOn Server service - however take care because you cannot restart it (since you will loose the connection to it once it stops).
