Correct. Asynchronous writes are not well-supported on Windows
servers. (They are not supported at all on Win-Playstation servers..)

It is whatever the the server is set to. This is by default ON for
Firebird and IB 5.6, OFF for InterBase 6.

The Forced Writes setting can only be set when the user has exclusive
access to the database. Thus, the first user MAY be able to set it but it
is unlikely that you can count on exclusive access unless SYSDBA explicitly
performs a successful shutdown using gfix -shut

So, in short, for each server you deploy, be safe and use gfix as SYSDBA
to first get exclusive access and then to set FW on. Keep the IBO setting
as dpbDefault.
