Adb server not responding [duplicate]

Answer 1

I found there was a process call "Tadb.exe" in Windows Task Manager. I guess Tadb.exe is a similiar adb application of Tencent. Because I got an alert of "android device detected by QQ" after I install the last version of Tencent QQ2013 Beta5 (6970) yesterday.

After I killed the Tadb.exe, the original adb.exe of Android SDK works again.

You can see the detailed proecss to solve this problem here: adb cannot run, adb server is out of date
