slave server problem

[DERYA GUNGORMUS (IT-TMO)]

  Hi all,
 I have a problem about my slave name server. It doesn't read the master
server's db file so it doesn't update it's db file. I restarted the named
deamon at my master server and slave server both but it didn't read it
again. I removed the db file at the slave server to force it to take it from
master server but it didn't! Does anybody know that what can i do about it ?
Thank you.
