As I understand it, there are several different definitions used for "van der Waals" forces. Some define van der Waals forces as "all intermolecular forces except Hydrogen Bonds," while I've seen other sources define van der Waals forces as "any intermolecular force, including Hydrogen Bonds."

So, I guess it depends partly on who's defining the term. Regardless, there's no clear and hard boundary between hydrogen bonds and [other] van der Waals forces. Whether they're considered separate things or whether a hydrogen bond is just another of the van der Waals forces seems to depend entirely on who's defining the term.
