Re: Roku Media Player no longer sees my media server
Windows Media Services is miserable in general. Offers little transcoding, no metadata, and has issues like this. More than likely, your Windows firewall has lost its setting allowing Media Sharing to be available. If your computer suddenly thinks you're now on a public network connection (I've seen that happen before, especially if there was a power issue), the firewall is blocking access.
One of many reasons I use a different DLNA server than what Windows offers.
