Let ${H_f}$ be the Perron-Wiener-Brelot solution of the Dirichlet problem for a resolutive function $f$ on the boundary $\partial \Omega$ of a bounded domain $\Omega$ in ${E^n}$. A point $y$ of $\partial \Omega$ will be called strongly regular if ${H_f}(x) \to f(y)(x \to y)$ whenever $f$ is resolutive and continuous at $y$. Necessary and sufficient conditions for strong regularity are given.
