I was wrestling with a few different issues. It finally came down to these few things: I needed to verify that the server was accessible from both Windows clients (XP Pro and Vista Home), and it was necessary to enable each Windows client to resolve the server hostname to its IP address. I did this by adding an entry to the hosts and lmhosts (for good measure) files on both clients. This was easy under XP Pro. It was a little more complicated under Vista -- I got to learn about the User Access Control, which was preventing me from saving changes to the hosts and lmhosts.sam files. After this I was able to view/read files on the share, but not write to it. I had to change directory permissions on the samba share (chmod o+w) to enable users to connect as guests with no authentication. I had assumed that since this is not mentioned anywhere that it was handled by Samba. I was finally able to create/copy files and folders to the share. Woo-hoo! The next step is to implement a form of security that will work for both Windows XP Pro and Windows Vista Home Premium. __________________________________________________ Do You Yahoo!?
