Preheat the oven to 375 degrees F.

In a small bowl, mix together the brown sugar and honey. Set aside.

In another small bowl, mix together the orange juice, peach nectar and chipotles.

Arrange the ham, cut end down, in a large baking dish. Pour a few tablespoons of the juice mixture over the ham and in between the layers. Bake for 30 minutes, basting every 10 minutes with the remaining juice mixture.

Remove the ham from the oven. Reserve about 1 1/2 cups of cooked juice from baking dish. Brush the honey mixture on the ham and return to the oven to bake for an additional hour until a crust forms and the ham begins to caramelize. Remove from the oven to a serving platter and serve with the reserved baking juice.
