The near horizon geometry of a fundamental string wrapped around an S1reduced to four dimensions is expected to be AdS2 x S2. A probe string analysissuggests a no-force condition indicating supersymmetry, which coincides withthe condition that the AdS2 is embedded in AdS3. We therefore consider the bulkstring theory in terms of a WZW model on AdS3 following recent proposals byDabholkar et. al and Giveon et. al. We find that conformal symmetry of themodel naturally leads to the no-force constraints obtained from the probes.Moreover, we are able to extract the values of the moduli that account for thevalue of the microscopic entropy. We also investigate higher derivativecorrections of the form alpha'^3 R^4 + flux terms to the horizon, in thecontext of type IIB supergravity. Imposing the no-force condition from theprobe analysis leads to a striking simplification of the equations of motion atthis order in alpha'. However, we argue that the value of the entropy can onlybe determined by considering all orders in alpha'.
