just use the advanced button to configure the DB path, then you can start the server.
Once the server is running, you can connect an SBAdmin to it.
If something is wrong on the Windows end and they shut down that server, move the SB db to another server with the same IP, will the clients see the new SB server?
if the box has the same ip then sure - as far as they are concerned, nothing changed. Don't go recreating server objects or anthing of course though.
