I think I see the problem. the problem isn't that it's lited, i just stated my laptop has an identical version and works perfectly, always had always will. the thing with windows networking is that it never was easy to configure. for example everytime i try to set up a lan network between my laptop and a desktop computer (via twisted cable) windows ALWAYS sees it as public and i can't change that. on the other hand desktops with dsl connections can always be marked as home. a friend of mine recently lost all his documents (plus a considerable music library) to a "hacker" who just accesed his share over the network, since it wouldn't make sense to allow sharing on a public network (aka the on in the room) but only on a home network (which can be marked as the vulnerable dsl connection). windows 7's troubleshooters and diagnostics are better at pointint out the problems but not necesarily solving them, so i'm relying on the online support recommended by them, which among other places could be here. firewall and ics are up and running, homegroup is working (though i never use it). using default settings i dont know why sharing would only work in one direction. i can't share anything and i can't save any sharing options, please help! thanks.
