This article addresses a problem that may occur when you try to enable media sharing in Windows Media Player. After checking the Share my media option on the Media Sharing window and clicking OK, the computer locks up for a bit and then does nothing. Normally, a window is supposed to open, providing you with the required options to fully enable media sharing.
This problem commonly occurs because Windows Media Player Network Sharing Service may for some reason be disabled. To turn the service back on, perform the following steps.
1. Open Control Panel.
2. Open Administrative Tools.
3. Open Services.
4. Find Windows Media Player Network Sharing Service in the list and open it up.
5. Select Automatic for the Startup type. Click Apply.
6. Click the Start button and click OK.
Now try to enable Media Sharing again in Windows Media Player. It should work now and open the window.
If it still doesn’t work, the Universal Plug and Play Device Host and/or the SSDP Discovery Service may need to be enabled as well. Try following these same steps to enable those services.
