We present a next-to-leading Order calculation of the cross section for the leptoproduction of large-E\bot hadrons and we compare our predictions with H1 data on the forward production of $\pi^0$. We find large higher order corrections and an important sensitivity to the renormalization and factorization scales. These large corrections are shown to arise in part from BFKL-like diagrams at the lowest order.
