I've set up a CD-server which gets it's ISOs from a remote fileserver via cifs. To mount those ISOs I use fuseiso.
When I try to connect to such a fuseiso mount I get NT_STATUS_BAD_NETWORK_NAME, if I connect to a share that resides on the CD-server I can connect to it.
Why do the fuseiso mounts not work with Samba? If you need the full log samba creates I'm happy to post it to pastebin.
Server details: Ubuntu Server 12.04 amd64 Samba 3.6.3 fuse 2.8.6
