[newbie] Samba is not working in 8.2

[Beastie]

Hi,   I've just installed new 8.2 from Linux Format DVD.   My machine is a Pentium II 350MHz that I would like to install as Firewall/Router DNS Server SMB server (File Server for networked Windows machines) Print Server.   I used to have another machine running Windows 2000 Server that served the above purposes, the problem was that the machine was constantly under attack and in the end was defeated and became unusable.   I hope that by installing Linux, I could get away with some of the problems I was facing.   After installing 8.2 I setup DNS and Firewall, these work fine. But not Samba, I can see the Samba server when browse Network Neighbourhood only when I click to open this server the error was "Network path not found".   I tried to set system security to lower level, thinking that these might be the problem but to no avail.   What can I do now ?
