使用bind9.2.2.rc1,配置abc.com.cn的域，启动后显示：
＃。。。：zone abc.com.cn/IN: loading master file named.host :unknown  class/type
在w2k的客户端 >;nslookup www
Server:  www.abc.com.cn
Address:  192.168.1.100
DNS request timed out.
    timeout was 2 seconds.
*** www.abc.com.cn can't find xh.abc.com.cn: Server failed
>;nslookup mail

Server:  mail.abc.com.cn
Address:  192.168.1.100

DNS request timed out.
    timeout was 2 seconds.
*** Request to mail.abc.com.cn timed-out

是什么原因呢
