Master Server ID problem

[kenny w]

hi,
i would like to setup the replication for master and slave. i am using mysql 5.6 windows version. under the master , i set the my.ini file with following information :
server-id=5
binlog-format = mixed
port = 3307
log-bin = "C:/Program Files/MySQL/MySQL Server 5.6/mysql-bin.log"
datadir="C:/Program Files/MySQL/MySQL Server 5.6/data/"
basedir = "C:/Program Files/MySQL/MySQL Server 5.6/"
innodb_flush_log_at_trx_commit=1
sync_binlog=1

i restarted the mysql services. the problem when i check with the sql command SHOW VARIABLES LIKE 'server_id'; the server_id always show 1 even i set it to differ number.

please help what should i do ? thank a lot
