This error stops WMP from downloading playlists. It's usually a network or proxy issue. Try clearing the cache, resetting settings, or disabling IPv6 first.

Quick answer

For advanced users: clear the WMP cache, reset Windows Media Player settings via Control Panel, and disable IPv6 on your network adapter. If that doesn't work, check your proxy settings and Windows Firewall rules.

Why this happens

Windows Media Player (WMP) downloads playlists from the internet. Error 0XC00D109D means the player couldn't retrieve the playlist file. This usually happens because of a corrupted cache, a misconfigured network adapter (especially IPv6), or a firewall that's blocking WMP's internet access. I've seen it pop up most often right after a Windows update changes network settings, or when someone connects to a VPN and forgets to disconnect.

Fix steps

1. Clear the Windows Media Player cache

WMP stores temporary files that can get corrupted. Clearing them is quick and often fixes the issue.

  1. Press Windows + R to open the Run dialog.
  2. Type %LOCALAPPDATA%\Microsoft\Windows Media and press Enter. You'll land in the Media folder.
  3. Press Ctrl + A to select everything, then press Delete. If some files are in use, skip them—you can delete those later.
  4. Restart Windows Media Player and try playing the playlist again.

Expected: After deleting, WMP will rebuild its cache from scratch. The error may still appear if the issue is elsewhere, but this clears one common cause.

2. Reset Windows Media Player settings

If the cache clear didn't help, reset WMP to its default configuration. This restores the original settings without removing your music library.

  1. Open Control Panel (search for it in the Start menu).
  2. Click Programs, then Programs and Features.
  3. On the left, click Turn Windows features on or off.
  4. Scroll down to Media Features and expand it.
  5. Uncheck Windows Media Player. A warning pops up—click Yes to confirm.
  6. Click OK. Windows will remove the component. This takes a minute.
  7. Restart your computer.
  8. Go back to the same place and re-check Windows Media Player.
  9. Click OK and let Windows reinstall it.

Expected: After the reinstall, WMP opens with fresh settings. Your library should still be there because it's stored elsewhere. Try the playlist again.

3. Disable IPv6 on your network adapter

IPv6 can cause weird issues with WMP's playlist downloads. Disabling it forces your system to use IPv4, which is more stable for this player.

  1. Press Windows + R, type ncpa.cpl, and press Enter. Network Connections opens.
  2. Right-click your active network adapter (the one with a green bar or labeled as connected) and select Properties.
  3. In the list, uncheck Internet Protocol Version 6 (TCP/IPv6).
  4. Click OK and close the window.
  5. Restart your computer (or at least restart the network adapter by disabling and re-enabling it).

Expected: After a restart, WMP should download playlists without the error. Keep IPv6 disabled if this fixes it—you won't miss it unless you're on a pure IPv6 network.

If the main fixes fail

Try these alternative approaches when the above doesn't solve it.

Check proxy settings

If you use a proxy (or a system-wide VPN), WMP might be trying to connect through it and failing.

  1. Press Windows + R, type inetcpl.cpl, and press Enter.
  2. Go to the Connections tab.
  3. Click LAN settings.
  4. If Use a proxy server for your LAN is checked, try unchecking it and click OK.
  5. Restart WMP and test.

If you need the proxy for other apps, leave it on and instead add an exception for WMP. That requires more advanced steps, so I'd only do it if you absolutely need the proxy.

Reset Windows Firewall rules for WMP

Windows Firewall can block WMP's outgoing connections if a rule got corrupted.

  1. Open Windows Security (search for it in Start).
  2. Click Firewall & network protection.
  3. Click Allow an app through firewall.
  4. Click Change settings (you need admin rights).
  5. Scroll to Windows Media Player.
  6. If it's there, uncheck it, click OK, then go back and re-check it (both Private and Public).
  7. If it's not listed, click Allow another app, browse to C:\Program Files\Windows Media Player\wmplayer.exe, add it, and enable both boxes.
  8. Click OK and test.

Prevention tips

To avoid this error in the future, keep your Windows updates current. Microsoft has patched several WMP bugs over the years. Also, avoid using playlist files from sketchy websites—they can trigger the error or worse, contain malicious links. Stick to trusted sources like official radio station directories or your own library. And if you're on a VPN, disconnect before using WMP; most VPNs interfere with its playlist downloads. A final tip: if you rarely use WMP, consider switching to a modern player like VLC or MusicBee. They handle playlists better and don't have these legacy quirks. But if you're stuck with WMP for work or habit, these fixes will get you through.
