Windows 7: DLNA Problems from Bluray player: Media Server Access Is Not permitted

I am having problems with my LG BD570 blueray player accessing a laptop on my home network.
I can access files on my wife's laptop, via the blueray player DLNA function, but I receive the error message "Media Server Access Is Not Permitted" on the laptop.

I have tried to make sure the settings between the 2 computers are the same to include:
* Making sure media streaming options are all on
* Sharing my pictures music, etc with home network box is checked.

So far I keep getting the same error message on the Blueray player where it cannot apparently access the files on the laptop.



Any ideas?

Thanks,
Rob
