Hi Warren,
By default the share areas are not visible to guest users (ie users without an SME account). See /etc/smb.conf.
You probably have two choices:
1. Add SME user accounts for all browsing users on your network.
2. Hack the smb.conf file to allow guest user access. This would be done as usual through the template system - not just by editing the file.
Option 1 is definately preferable if you can manage it.
Otherwise, anyone know a better way ?
