ADB not running or starting

Question

When I try to start adb using the "adb start-server" command, the command line doesn't respond, and adb shows up for a second in the task manager, but then disappears. I've tried re installing, and a fresh copy of the SDK has the problem. When I type in "adb devices", the output is: "error: protocol fault (no status)" Any ideas on how I can fix this?

Also, when I update the SDK, I get this code: Starting ADB server failed (code -1).

Answer 1

The problem was that my parental control software was interfering with adb.

Answer 2

Try running adb kill-server and then adb start-server again.

After that, adb devices should work correctly.
