In the pic in #12 you show it being setup as anonymous, is there any reason for that? You also talk about IP of 10.x.x.x while the router is 192.x.x.x - I can see possible problems in both of these. Either the network should all in the 10.x.x.x range or the 192.x.x.x NOT both or you will have problems communicating especially if the computer is in the 193.x.x.x and the NAS is 10.x.x.x - I would go as far as saying they will not work together unless you have a bridge setup somewhere.
You might also find it advantageous to give the NAS a fixed IP (192.168.0.32 is the default) and make sure you use the name of the computer if it is assigned an IP by DHCP.
In the setup I have here the server has a fixed IP as does the NAS - that way all the other computers can have those destinations 'hard wired' and we've never had any problems, likewise we don't have windows but people arriving with windows notebooks are able to connect to our server and the NAS without problems and upload and download as necessary.
