I've spent a day or two on this same issue. Here is what I have found. You can use the file manager on your ppc to explore network shared drives. Doing that you can copy files between your axim and any shared drive on the network. Almost cool, you can copy them but you can not use a file that is on a network share. The share only appears in the file manager. How about getting widows media to also see the share. No can do. Yesterday I downloaded Resco File Manager because most people here seem to use it. It has a 14 day trial. It has the network drive map feature and I used it to map a drive. The share appears in its file manager, but it still does not apper in windows media nor Picture viewer. Whats the point? Having got this far I now find I can no longer surf the web in fact I can not even ping the router. When I try to load a page I get an immediate small pop up box that says the page can not be found, not the ususal you can not connect. Seems I have lost the DNS somehow?? So I still have some work to do.
Anyway - go to
