If you are using the MediaLounge mode on your DSM-750 to stream media via Windows Media Player, you may have noticed that it will not share files that are located on another computer or server (in other words, a network share). Even after you add the network share as a monitored folder in Media Player Library, you still cannot see those files in your DSM-750.
According to Microsoft's Media Player FAQ (
http://www.microsoft.com/windows/windowsmedia/player/faq/sharing.mspx), here is what you need to do:
If you want to share files in a monitored folder that is located on another computer (for example, a folder on a network share), the remote folder must have the appropriate Windows access permissions assigned to it and the computer that contains the library you want to share has remote content sharing enabled. You can enable remote content sharing by performing the following procedure on the computer that contains the library you are sharing.
1. Click Start, click Run, type regedit, and then click OK.
2. In the registry tree (on the left), expand HKEY_LOCAL_MACHINE, SOFTWARE, Microsoft, MediaPlayer, and then Preferences.
3. Right-click HME, point to New, and then click DWORD Value.
4. Type EnableRemoteContentSharing, and then press ENTER.
5. Right-click EnableRemoteContentSharing, and then click Modify.
6. In the Value data text box, type 1, and then click OK. If you later decide to disable remote content sharing, you can repeat this procedure and change the value to 0.
