If fbserver.exe is the server and the service is running, and you don't see
port 3050 displayed as LISTENING, then the port is firewalled.

Yup. Well, it's the same firewall in costlier clothes. If you are using
events in your app, you'll also need to open another port. To make this
non-random, make it port 30050 and set the RemoteAuxPort parameter in
firebird.conf to this (remembering to uncomment the entry).
