Hi Codebue Fabio,

Thank you for reply.

> One of two RDBMS have to change port. Infact they use port 3050!

At the server I've changed the RemoteServicePort to 3060 in the file
Firebird.conf and still facing problem on connection from the client
using connection string
192.168.0.50/3060:c:\testfirebirddb\myfirebirddb.fdb

AT the client pc has already installed with firebird with
option "client only installation"

> Noone you can use gds32.dll to connect to database with firebird

Is it mean that the gds32.dll which actually was installed from my
if7.5 dev can be used for the client-server connection.
