Slave I/O: Master command COM_REGISTER_SLAVE failed: failed registering on master

[Christopher Swearingen]

I'm trying to set up a replication slave. Both the master and the slave are Win2003 servers running MySQL v5.1.34. The slave is not registering on the master and I'm perplexed.

On the Master Using MySQL Administrator (v1.2.17) I've got is configured with these settings:

 
  -- Server ID = 1 
  -- Show Slave authentication Info = True (checked in MySQL Administrator)
  -- Log slave updates = true (checked)
  -- Binary logging enabled

Using MySQL prompt;
  -- executed the command  GRANT SLAVE REPLICATION ON *.* TO'root'@'192.168.1.17:3306' IDENTIFIED BY '[slave's PWD]'; (Query Ok, 0 rows affected)

I've got the slave's MySQL Administrator's replication tab set up as:

 -- Server ID = 2
 -- Show Slave authentication info = true (checked)
 -- Report Host = 192.168.1.17
 -- Report User = Web02
 -- Report Password = [Slave's Password]
 -- Master hostname = 192.168.1.5

On the MASTER

 -- Executed a FLUSH TABLES WITH READ LOCK; 
 -- I noted the current log file (mysql-bin.000005) and position (3851446) with a SHOW MASTER STATUS; command
 -- took a snapshot of the data on the master using the MySQL Administrator backup utility to run all schemas to an SQL file.

On the SLAVE

 
 -- imported the MASTER data via a restore in MySQL Administrator
 -- Executed the command CHANGE MASTER TO MASTER_HOST='192.168.1.5', MASTER_USER='Web02', MASTER_PASSWORD='[Slave's PWD]', MASTER_LOG_FILE='mysql-bin.000005', MASTER_LOG_POS=3851446'; (Query Ok, 0 rows affected)

After stopping and restarting the SLAVE's MySQL service I get the following log:

Trying to start the server ...
Server was started.
The syntax 'for replication startup options' is deprecated and will be removed in MySQL 6.0. Please use 'CHANGE MASTER' instead.

Neither --relay-log nor --relay-log-index were used; so replication may break when this MySQL server acts as a slave and has his 
hostname changed!! Please use '--relay-log=Web02-relay-bin' to avoid this problem.
