Fedora Users — [FC2] Anyone with successful Samba connections?

Anyone here successful with Samba and FC2? By successful I mean the following:

1. Browse Samba shares on the network using Nautilus (smb:///). - This was possible under FC1, by opening up the following ports: Incoming tcp 139, 445 Incoming udp 137:138 Outgoing udp 137 But I can no longer get it to work. Every other computer on our network (Windows XPs and Fedora Core 1s) can browse the Windows workgroups and shares but me.

2. Have other computers (Windows or Linux or whatever) successfully access Samba shares on your computer, using SHARE level security and a publicly accessible "shared" folder. - The situation is basically this... I am running a laptop and would like others to be able to access a "shared" folder I have created, without being prompted for a username and/or password. When using a Windows machine with the same account name and password, I can access the share. But when on another machine withouy my username, it keeps prompting for a password. What is strange is that I have basically used my old FC1 configuration, which worked successfully. Anyone have a configuration that would work for what I need, a public no-password folder?

Samba configuration:
        workgroup = WORKGROUP
        server string = Samba Server
        log file = /var/log/samba/%m.log
        max log size = 50
        security = SHARE
        encrypt passwords = yes
        smb passwd file = /etc/samba/smbpasswd
        socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
        wins support = yes
        guest ok = yes
        dns proxy = no
[shared]
        comment = Shared Folder on portablepoch
        path = /home/shared
        guest ok = yes
        guest only = yes
        writeable = yes
        printable = no
        create mask = 0664
        directory mask = 0775
        force user = thepoch
        force group = thepoch

Is there a specific bugzilla or solution I should be looking at? Thanks.
