Yes. Web Projects have a separate mount path. This is for two reasons: first, the web project CIFS projection differs from a standard CIFS projection, in that it return not only a view of current files and folder but also historical snapshots; second, web projects are typically only accessing via CIFS by power users (using tools like DreamWeaver) and developers, and normal everyday business users staying in the context of the web app to use browser-based tools like our Web Forms to create web content is a more structured manner (via XML). Where business users do - and should - use CIFS is for their document libraries and collaboration projects. CIFS projections for website tend to be confusing for business users, simply because the directory structure of the website is arcane to them (it was laid out by some site designer / developer) and contains lots of assets that are meaningless / scary to them.
To mount the Web Projects CIFS projections, use the following path: \\servermachine_a\avm.
Cheers and let us know if you have any further questions.
