HFS error when using list files(

I am trying to list files on a shared server volume but I get the attached error. I have permissions set for “Everyone” on the volume, the folder and the files. I’ve tried it on two different servers.

I should be able to list and manipulate files from a mounted server, right?

Are you sure that’s an error? It doesn’t say “error”. It looks like it might be a list of folders.
