This should never happen when Eagle is used properly. You have to go out of
your way to make this possible.

DRC will tell you about differences between the board and the schematic.
However by far the best approach is to make sure they never get out of sync
in the first place. Always make sure that the board and schematic are both
open when making changes in either. I don't think it's possible to get them
out of sync if this is the case.
