Sometimes I can browse my windows XP media server & sometimes I can't.
Rebooting doesn't make a difference.
I'll get a conection refused error when I try then 10 minutes later it's fine then if I try again, no go?
Internet access always works.
I don't have problems with my open-elec or Geexbox PC's running XBMC or my phoenix box so I know it isn't the windows machine.
It's an older p3 1.2ghz with 384MB of RAM and an mx4000 video & a USB netgear adaptor if that helps.
I'm also running Enlightenment on it if that matters.
