Try the following:

• Restart your phone.
• End adb.exe process in Task Manager (Windows). In Mac, force close in Activity Monitor.
• Issue kill and start command in platform-tools
  • C:sdkplatform-tools>adb kill-server
  • C:sdkplatform-tools>adb start-server
• If it says something like started successfully, you are good.

For anyone using OSX (Im aware OP isnt):
What worked for me in the end was removing the android settings folder in the home directory.

rm -Rf ~/.android

android – How to resolve the ADB server didnt ACK error?

For me it didnt work , it was related to a path problem happened after android studio 2.0 preview 1, I needed to update genymotion and virtual box, and apparently they tried to use same port for adb.

Solution is explained here link!
Basically you just need to:

1) open genymotion settings

2) specify sdk path for the adb manually

3) adb kill-server

4) adb start-server
