Remove any restrictions on the shares. Like valid user and that sort of
thing.

I'm slightly closer to finding the cause of this problem. I set the smbd
log level to 7 and found the following entries when trying to list the
contents of the share:
[2008/05/21 15:27:05, 5] smbd/uid.c:change_to_user(273)

The "Permission denied"s correspond exactly to the files and directories
that are missing. As you can see, it somehow can't stat (whatever that
is) the existing files, but it can the new files. Which is bizarre,
since their permissions are the same. We need a real Samba internals
guru. What exactly is it trying to stat, and how is it possible for that
to succeed for some files but fail for others while having the same
permissions?
Kind regards,
