Actually, you can use a very simple Lotuscript agent to connect to a server and walk through all databases on the server, using the NotesDbDirectory class. Here is some code, modified slightly from what's in the 6.5 Help files - this dumps the title and path of all databases to a csv file. Note: the one argument to the GetFirstDatabase method let's you specify which objects on the server you want to scan - 1247 is the constant for "Databases" - basically, all NSF files. There are other constants for finding templates only (NTF's), only database with replication enabled, etc.
Sub Initialize
Dim db As NotesDatabase
Dim f As Integer
f = Freefile
Open "c:\dbExport.csv" For Output As #f
Dim dbdir As New NotesDbDirectory("") ' opens LOCAL - put a server name here
Set db = dbdir.GetFirstDatabase(1247) ' all databases - NSF, NSG and NSH (no templates)
While Not(db Is Nothing)
Print #f, """" + db.Title + """, """ + db.FileName + """"
Set db = dbdir.GetNextDatabase
Wend
Close #f
End Sub
