We have remote locations each with 2 ASUS media extenders that stream from a computer with a shared Media Player library. Lately, several of these locations experience the "wmpnetwork.exe" service throttling the CPU to 100% usage. Killing the service only results in it starting back up, and so far the only temporary solution is to uninstall Media Player. A lot of these computers are also about 3-5 years old. Could it just be a case of outdated hardware not being able to do everything we ask them to do? Edit: all running Windows XP and Windows Media Player 11
There is probably nothing wrong with the hardware. Try uninstalling media player from the Windows components in control panel and the remote differential compression service.
Restart computer and restart media player and remote compression service. This will hopefully re-configure corrupted media player and stop it cycling and using all your resources.
If when you re-enable media player the problem returns you will have to use an alternate media player until next version upgrade
