I've fixed many of these but the fixes run the gamut from changing router settings to telling the PC to not go to sleep to changing to another server software.
In light of that, do you think it's time for makers to only offer such features from machines directly under their control? That is, move away from the PC?
I've connected my new Samsung 46D7000 Smart TV to my home network to share music and photos stored on my main PC. I've used Windows 7 Home Group to do this.
It finds them but after a few minutes it closes down and a "Device Not Connected" sign comes on the screen. The broadcast reverts to television.
I've tried using the Samsung AllShare software and it still happens.
Has anybody else had this problem and succeeded in resolving it?
