ADB server didn't ACK

用数据线连接android手机到pc，却在eclipse中Device view中未发现设备信息。提示错误信息如下：
adb server is out of date. killing...
ADB server didn't ACK
* failed to start daemon *

确认手机上的usb调试已打开，adb kill-server,adb start-server 还是未能解决。
stackoverflow上搜索一番得到解决办法如下

C:\Documents and Settings\Administrator>adb nodaemon server
