No it is using fbclient.dll. gds32 is the dll that IBX expects to
find. Firebird can create a fbclient.dll disguised as gds32 to trick
IBX into connecting. It can be generated by the installer or using one
of the included tools (instclient.exe??). If your server has had
Interbase installed (and Delphi does install IB if you don't uncheck
the box), then you may have an incompatible client library in you path
somewhere (SYSTEM32 etc)

Make sure it is a Firebird one. Right click --> Properties and check
the comments. It should say something like:

"This product created by The Firebird Project" ... blah blah blah

Terminal Services does not support local connections, which will
present all sorts of interesting challenges when the security database
no longer accepts TCP connections.

Here is a snipped of working code on FB 1.5 SS

bs := TIBBackupService.Create(self);

try
bs.BackupFile.Text := BackupFBKFile;
bs.DatabaseName := Alias;
bs.LoginPrompt := False;
bs.Params.Append('user_name=sysdba');
bs.Params.Append('password=masterke');
bs.Protocol := TCP;
bs.ServerName := 'localhost';
bs.Verbose := True;

bs.Attach;
bs.ServiceStart;

while not bs.Eof do
begin
slBackupLog.Append(bs.GetNextLine);
end;

bs.Detach;

finally
bs.Free;
end;

Hope that helps
