Öfter mal in die Designer Hilfe schauen
Dort steht:
For local calls, the protocol is "notes" and the host is empty, so the URL starts with "notes:///" ("notes," colon, and three slashes).
The database can be specified by name or replica ID. The name can include spaces (you can substitute plus signs for the spaces but it is not necessary). The name need not include the type suffix if it is NSF. The replica ID can be specified as the 16-digit ID by itself or the 16-digit ID prefixed by two underscores and suffixed by the file type (for example, ".nsf").
Du willst aber wohl die Datenbank auf dem Server öffnen, oder?
Also dann nur "// und dann Angabe des Host !
