Targets do not go in the black out unless somebody puts them in black out. Is there any other administrator who put these targets in a black out? If you do not think these targets should be in a black out , you can simply click on the blackout link and take those targets out of the black out mode.
Restart will not fix this problem.
Thanks sharma. You are the GURU man. Thanks for your help. I asked my boss whether he put it it blackout modes . Thanks.
