Many thanks to Martin and John for your suggestions. The problem was solved by changing database setup to
$CFG->dbuser = "sailomv";
$CFG->dbpass = "**********"; .
Other problems are :
Warning: Failed opening '/theme//header.html' for inclusion (include_path='.;c:\php4\pear') in c:\easyserv\www\moodle\lib\weblib.php on line 625

and more ....
This is my "config.php"
$CFG->dbtype = "mysql";
$CFG->dbhost = "localhost";
$CFG->dbname = "moodle";
$CFG->dbuser = "sailomv";
$CFG->dbpass = "**********";
$CFG->prefix = "mdl_";
$CFG->wwwroot = "http://127.0.0.1/moodle";
$CFG->dirroot = "";
$CFG->dataroot = "/moodle/data";
$CFG->buggy_referer = false;
I think there should be something wrong in my config.php that I had to edit "lib/setup.php" before this.
I understood that moodle need to setup only one "config.php" file.
