Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Was this after an update or restore? First try a reset by holding the home and lock buttons until the apple disappears and reappears.
If that doesnt do it, place the tablet into recovery mode and restore: http://support.apple.com/kb/HT1808
