Why not just relog the character in the same place then? =/
*resets*
*get disconnected*
*relogs*?
I don't believe you can be force disconnected.
As Yuyuko said, you used to be sent to a place where you can't do anything and you'd be forced to relog, when you came back you were always back in Pront.
Point being you can do things to force the player to dc of their own free will, but I don't think they can DC you by choice.
