Without getting too technical, this is an issue with Windows sometimes not recognizing network resources. But there is a fairly easy solution (although you may have to use this technique every time).
First, select Network in Windows. Then click on the icon showing a globe and a monitor: Here is what it would look like...
The word "Network" will then appear in the address bar. First, try replacing the word Network with "\\splayer.local". If that does not work, you will need the IP address of the StreamPlayer. Enter the IP address like this format: "\\192.168.1.1" using the correct IP address for the StreamPlayer.
You should then see the StreamPlayer show up as a network device.
I have seen this issue with my own computers and even have other Windows computers on my network that are not recognized initially. But if I use the IP address method above, I have no trouble manually accessing them.
Let me know if this does not work out for you.
