Troubles setting up Samaba

I'm not having success setting up a network using Samba.

In Samba I've done the following:
Startup at boot, open port in firewall
Shares: added a folder, added the option "guest ok" yes
Identity: workgroup, not a DC
WINS: Remote WINS Server, Retrieve WINS server via DHCP
Trusted Domains (blank)
LDAP settings (bland)

Firewall Allowed Services:
Netbios Server
Samba Client
Samba Server

Firewall Interfaces:
Wireless Network External Zone

Any help would be appreciated.
