Let 𝔞 denote an ideal of a commutative Noetherian ring R, and M and N two finitely generated R-modules with pd M < ∞. It is shown that if either 𝔞 is principal, or R is complete local and 𝔞 is a prime ideal with dim R/𝔞 = 1, then the generalized local cohomology module $H^i_{𝔞}(M,N)$ is 𝔞-cofinite for all i ≥ 0. This provides an affirmative answer to a question proposed in [13].
