If you would like to get this quickly and simply without even having to start the quest, go to the back of Tenpenny Tower and enter the Door to Metro Access & Generator down the stairs. Hack the terminal and Roy will appear on the other side of the grating telling you to meet him out front. Go speak to him and and the quest will be completed, but giving you bad karma.
It is possible that the Door to Metro Access & Generator may be locked. Gustavo and Herbert Dashwood both have a key.
