Abstract: We classify four-dimensional connected simply-connected Lorentzian symmetric spaces M with connected nontrivial isotropy group furnishing solutions of the Einstein-Yang-Mills equations. Those solutions are built with respect to some invariant metric connection. in the bundle of orthonormal frames of M and some diagonal metric on the holonomy algebra corresponding to Lambda.
