Error C00D10B3 or C00D10B5 means that Windows Media Player isn't "seeing"
your internet connection. It doesn't mean you are not connected, rather it
is just not being told you are not connected. This can be caused by two
things most of the time...
(1) A firewall blocking the traffic or (2) A configuration problem within
WMP.

If the above doesn't help you you might also want to try reinstalling WMP
over itself. Depending on how WMP was installed on your machine you may
already have the installer. If you do it is located in C:\Program
Files\Windows Media Player\Installer. The file name of the installer is
"mpsetupxp.exe"
If you don't see the folder then run C:\Program Files\Windows Media
Player\setup_wm.exe and that will re-download the installer and install it.
If the site doesn't help you fix it the best option is to ask actually
Product Support. Especially if you are running Windows 9x (i.e Win98,
WinME, Etc)
