If it's XP it's better change the gdb extension to fdb to avoid the
System Restore problems. Maybe a better way to connect is to create
an alias in the aliases.conf file located in the root of your
firebird installation directory:
pperfect = C:\PPerfect\SQLData\pperfect.fdb

and then connect using
hostname:pperfect
