FWIW, the NAS uses BusyBox Linux. Not sure if I can ask questions about that here.
Try to see with Wireshark (ex etheral). It is included in distro and even in very simple configuration can tell you what is wrong.
Hi here is the wireshark output. Any idea what it means? If you have a minute? I've no idea!

Lynn,
Either the firewall is blocking broadcasts from outside (the NAS side) to inside (the server side) or it is blocking outgoing netbios packets. The NAS box is trying to do a netbios name query to determine the address of the server - it is then getting no response so it tries a DNS query (which goes to your ISP's DNS, which probably doesn't know where your server is anyway, since it is on your internal network).
The NAS box then tries to force a browser election by claiming to be the master browser for your network (your server 192.168.1.3 probably should be the master browser). Apart from DNS, nowhere do I see the server responding to the netbios name queries and (as Rajko noted elsewhere) your trace finishes before the browser election is completed.
Does your ADSL router have a built-in firewall? If so, can I suggest that you enable that and turn off Suse Firewall? That's how I run my network - I have in fact 2 routers between the network and the outside world - a wireless router/switch inside the network which talks to the DSL/VoIP modem/router that is the interface to outside. Both of these devices have firewalls enabled (probably a bit over the top - one would do) so I dont' bother with the software firewall (SuSE Firewall) on the server and all Windoze boxes have their Windoze firewall turned off too.
That way, all machines talking to the server are inside the firewall and I don't have to worry about access problems between machines (it also helps that I'm the only user, apart from the wife very occassionally).
HTH.
Rodney.
Phew. Thanks for taking all that time Rodney. Yes. The adsl router does have a firewall. It's a good idea if SuSEfirewall2 doesn't work. It has these options: Enable DOS and Portscan Protection : SYN attack : FIN/URG/PSH attack : Ping Attack : Xmas Tree attack : TCP reset attack : Null scanning attack : Ping of Death attack : SYN/RST SYN/FIN attack : Which would you suggest setting to 'yes' bearing in mind the my NAS runs a bittorrent client (ctorrent with dctcs). There's also NAT which I've no ports forwarded except ALG as follows(the d- link default I think): PPTP : IPSec (VPN Passthrough) : RTSP (Online Video Streaming) : Windows/MSN Messenger : (automatically disabled if UPnP is enabled) FTP : H.323 (Video Conferencing) : SIP : Isn't just NAT good enough for what I want to do? Listen to mp3's and avi's I have on my laptop? If no one can connect to me from the outside then I'm OK internally on the lan no?
