We present a mean-field solution for a quantum, short-range interacting,disordered, SO(3) Heisenberg spin model, in which the Gaussian distribution ofcouplings is centered in an AF coupling $\bar J>0$, and which, for weakdisorder, can be treated as a perturbation of the pure AF Heisenberg system.The phase diagram contains, apart from a N\'eel phase at T=0, spin-glass andparamagnetic phases whose thermodynamic stability is demonstrated by ananalysis of the Hessian matrix of the free-energy. The magneticsusceptibilities exhibit the typical cusp of a spin-glass transition.
