adb is Android Debug Bridge.

To restart adb by command line:

adb kill-server
adb start-server

To restart adb in Eclipse:

Window > Show View > Other... > Android/Devices
When the view is showing: View Menu of "Devices" > Reset adb

When I do "Reset adb", I get this error messages: [2012-04-19 12:53:35 - DeviceMonitor]Adb connection Error:An existing connection was forcibly closed by the remote host [2012-04-19 12:53:36 - DeviceMonitor]Connection attempts: 1 – siva636 Apr 19 '12 at 07:25
@DUKE It seems that the Android virtual device has an active connection with adb, that's why those warning message appears. I suggest to close Eclipse and use the command line method to restart adb, and then restart Eclipse to see how it works? – Hailei Apr 19 '12 at 07:31

ADB stands for Android Debug Bridge.

Android Debug Bridge (adb) is a versatile command line tool that lets you communicate with an emulator instance or connected Android-powered device.

This info and more can be found here, on my blog.

As for restarting adb server you can execute following commands

adb kill-server
adb start-server

As for Eclipse simply close the IDE and restart/reopen. Infact restarting Eclipse should restart adb server as well.

I saw this problem on Eclipse, and it reported that I needed to 'reset adb from the Device's view'. The adb kill&restart-server sequence didn't work for me, but I was successful with just disabling and then re-enabling the 'USB debugging' check box in the phone's Settings->Developer Options
