I have similar problems here. I have a windows 2000 fileserver (which is a domain controller as well). And I have two Red Hat 9 inux clients.
I'm opening up a browser on the first RH box and doing a smb://192.168.1.98
where 192.168.1.98 is my fileserver. It prompts for credentials which I enter.
I double click some shared folders in my fileserver, and it lists the contents fine. But when I go to double click it nothing happens (assuming access error)
My other linux box (also RH 9 setup the same) can see the shares. But when you double click a folder, you cannot see the contents.
Any ideas? I did no configuration on the samba client. This is all out of the box.
