Hi there.
Have had same problem before but now it have come back and it is much worse I guess, cause I have no idea of to fixe it.
When I first bought the dune it didnet work either but it like fixed it self somehow

but after I reinstalled windows im back to the old problems again
The problem is that when try to connect to my PC with the Dune I just get "Network resources is not accesiable"
First off just so you know I have win 7.
What I have done so Far is to Share my movie Folder on the PC with "all"
Have cat 5 cable from dune to the Swtich and cat 5 cable from the switch again to my PC
Made a new network folder on the main window on Dune.
In that I have done like this:
Name: Name on the folder on the Dune
Server: The name of my PC
Folder: The name of the Movie folder on the Computer
Username: Nothing
Password: Nothing
And when I push that shortcut the message "Network resources is not accesiable" comes up.
But when I push the Network butten on the dune and go to the "Homeworkgroupe" I can see my PC name there and some other PC on the network. But when I go into either of thouse folders it's totaly empty.
So It seems like I'm able to see my PC with the dune, just not able to see my folders and files.
I have alsow tryed to do all this (what i have written above here) with my windows firewall Turned OFF But with no help at all.
And when i go into Network on my PC I can see the Dune aswell. So good thing they can see eachother I guess

But how dos that help me when im still not able to see movies on me TV
And I maybe think I have to do somthing in the Firewall, just maybe.
In the "Windows-Firewall advanced securety" I might have to do somthing in the "Incomming rules" But I dont know
So know I ahve tryed all weekend to fixe this so I can see movies but nope looks like im not good enough with computers to figure this out.
So then this is my last chanse before I give up and just sell my dune and hope that you guys might be able to help me out!
Sorry for my bad English!
