至于dhcpd.lease,是dhcpd自动生成的，在没有人用的时候，最好清空一下

summer820228

bingosek    谢谢你的回复.   

你是建这个双机的时候试用 如果你地址池中只用6个地址 如果你DOWN掉一台的时候.   

如果你用ipconfig /release 命令.  
然后在用ipconfig /renew  命令。就会获得一个新的IP.   直到6个地址你全部获得一次,然后你的DHCP就在也不能分配IP了.

两台都好使的时候是什么问题都没有的

bingosek

我们这里没有出现过这样的情况，如果是这样的话，你查查dhcpd.release,原来的IP为什么没有释放掉
