We show that the prediction of mode-coupling theory for a model of a network-forming strong glass former correctly describes the wave-vector dependence of the Debye-Waller factor. To obtain a good description it is important to take into account the triplet correlation function c(3), which we evaluate from a computer simulation. Our results support the possibility that this theory is able to describe accurately the nonergodicity parameters of simple as well as of network-forming liquids.
