help with rndc fail

[pyh at mail.nsbeta.info]

Hello gurus, 

my rndc related commands in bind master with multi-views run fail,but in 
slave it's running correctly. 

# rndc status
rndc: connection to remote host closed
This may indicate that
* the remote server is using an older version of the command protocol,
* this host is not authorized to connect,
* the clocks are not synchronized, or
* the key is invalid. 

Here is the named.conf for master.
Please help,thanks in advance.
