zeos와 firebird1.5를 사용했어요..
Local에서는 제대로 되는데
remote에서는 디렉토리나 화일존재여부를 체크할수 없습니다.
참고로 저는 코드가 000이라면 000이라는 폴더를 동적으로 만들어서 그안에 DB를 관리하려구 해요..  
제발좀 답변 부탁해요..

Procedure DataBaseConnect(xZConnection: TZConnection; xHstName, xPathName, xDBName: String);
var
Props: String;
begin
with xZConnection do begin
  Properties.Clear;
  HostName := xHstName;
  Database := xPathName + '\' + xDBName;
  User := 'sysdba';
  Password := 'masterkey';
  Protocol := 'firebird-1.5';
  Props := 'CreateNewDatabase=CREATE DATABASE ''';
  if (HostName <> '') or (HostName <> UpperCase('LocalHost')) then
     Props := Props + xHstName + ':';

  Props := Props +  xPathName + '\'+ xDBName + '''' +
  ' USER ''' + xZConnection.User + '''' +
  ' PASSWORD ''' + xZConnection.Password + '''' +
  ' PAGE_SIZE 16384 DEFAULT CHARACTER SET ISO8859_1' +
  ' FILE '''+ xPathName + '\'+ xDBName + '2.fdb''' + // create a 2nd file
  ' LENGTH=50000 STARTING AT PAGE 50001';

   {$I-}                                                                                              
   showmessage(mPathName);
   if not DirectoryExists(mPathName) then
     mkdir(mpathName);
   raise Exception.Create('Cannot create' + mPathName);}

    if not FileExists(xZConnection.Database) then
    Properties.Add(Props);
    Connect;
end;
end;
