Fix NS_E_SERVER_UNAVAILABLE (0XC00D2EE6) on Windows Media Center

You're sitting down to watch a recorded show or stream a movie through Windows Media Center, and instead of the video, you get that annoying box: NS_E_SERVER_UNAVAILABLE (0XC00D2EE6). It usually pops up when Media Center tries to fetch something from a network server — like a shared folder on another PC, an extender, or even a TV tuner. I've seen it happen most often after a Windows update messes with network settings, or when the date on the PC is wrong. One time, a user's PC clock was off by three days, and boom, that error showed up for every stream.

What's Actually Going On?

This error is a generic "I can't find the server" message. It means Media Center tried to connect to something and got zero response. The root cause is usually one of three things:

• Network issue: The shared folder or media server isn't reachable. Maybe the PC's IP changed, or the share is offline.
• DRM trouble: Media Center uses DRM (digital rights management) for protected content. If your date/time is wrong, the DRM check fails, and you get this error.
• Firewall or antivirus blocking: Windows Firewall or third-party security software can silently block Media Center's traffic.

How to Fix It (In Order)

Don't skip steps. Do them in this order — it saves time.

Step 1: Check Date and Time

1. Right-click the clock in the taskbar, choose Adjust date/time.
2. Make sure Set time automatically and Set time zone automatically are both ON.
3. If they're already on, turn them off, then on again. This forces a resync.
4. Restart Media Center.

I've fixed half of these errors just with this step. It's that simple.

Step 2: Test the Network Share (If You're Using One)

1. Open File Explorer and type \\server\share (replace with your actual server and share name) into the address bar. Press Enter.
2. If you get an error, the share is unreachable. Check that the server PC is on, the share is still shared, and both PCs are on the same network.
3. If the share works but Media Center still fails, try mapping the share to a drive letter (e.g., Z:). Right-click the share, choose Map network drive, then add it in Media Center using that drive letter.

Step 3: Allow Media Center Through the Firewall

1. Go to Control Panel > Windows Defender Firewall > Allow an app or feature through Windows Defender Firewall.
2. Click Change settings (needs admin).
3. Look for Windows Media Center. Make sure both Private and Public boxes are checked.
4. If you don't see it, click Allow another app and browse to C:\Windows\ehome\ehshell.exe.
5. Click OK and restart Media Center.

Step 4: Reset Media Center's Network Settings

Sometimes Media Center just gets confused. Resetting its settings can clear it.

1. Close Media Center.
2. Press Win + R, type regedit, and hit Enter.
3. Go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Media Center.
4. Right-click Media Center and choose Export to back it up.
5. Then right-click Media Center again and choose Delete. Confirm.
6. Restart your PC and reopen Media Center.

This is a bit more advanced, but it works for the stubborn cases. Just don't skip the backup — trust me.

Still Failing? Check These

If you've done all the above and the error still appears, check these:

• Antivirus software: Some AVs block Media Center's network access. Temporarily disable your AV (not the firewall) and try again. If it works, add an exception for ehshell.exe and ehexthost.exe.
• Windows Media Center Extender: If you use an extender (like Xbox 360), make sure it's updated and on the same network. Re-add it via Media Center's Extender menu.
• Recorded TV folder: If you're recording TV, check that the folder where recordings are saved still exists and has write permissions. Go to Tasks > Settings > TV > Recorder > Recorder Storage in Media Center.

One more thing — check for Windows updates. I've seen this error fixed by a cumulative update after a fresh install. Go to Settings > Update & Security > Windows Update and click Check for updates.

That's it. You're likely to be watching your show in a few minutes. If none of this helps, it might be a deeper network issue — check if your router is blocking multicast traffic, but that's a separate fight.
