Fix DRM Secure Clock Error 0XC00D11DB

The 30-Second Fix: Sync Your Computer's Date and Time

This is the most common cause. Windows uses a secure clock to verify DRM licenses on your media files. If your PC's clock is even a few minutes off, the sync fails with error 0XC00D11DB. I've seen this happen when a laptop's CMOS battery dies, or after a time zone change from travel.

Here's how to fix it fast:

Right-click the clock in the bottom-right corner of your taskbar and select Adjust date/time.
Turn on Set time automatically and Set time zone automatically.
Click Sync now under Synchronize your clock. After a few seconds you should see a message saying your clock was successfully synced.
Close the window. Try syncing your media again in Windows Media Player.

If that didn't do it, the problem might be more stubborn. Move to the next fix.

The 5-Minute Moderate Fix: Reset DRM Licensing

Sometimes the DRM data itself gets corrupted. This happens more often than you'd think — especially after a Windows update or if you've installed new codec packs. Resetting DRM forces Windows to rebuild the secure clock certificate from scratch.

Important: This will delete your existing DRM licenses for all media. You'll need to reauthorize purchases from services like Amazon Music or iTunes. Don't worry, you won't lose the files themselves — just the licenses that let you play them.

Close Windows Media Player completely. Check your taskbar to make sure it's not minimized — right-click the icon and select Close window if needed.
Open File Explorer (Win + E). In the address bar, paste this exact path and press Enter:
```
%windir%\ServiceProfiles\LocalService\AppData\Local\Microsoft\Media Player
```
You'll see a folder called DeviceMetadata and maybe some other files. Delete everything inside this folder. Don't delete the folder itself — just the contents.
Now open Windows Media Player again. You should see a message saying it's setting up DRM for the first time. This is normal.
Try syncing your device. The error should be gone.

If you still see the error, don't give up — the advanced fix below works on nearly every system.

The Advanced Fix (15+ Minutes): Clear DRM via Command Line

This method reaches deeper into Windows. It's what I use when the moderate fix fails. It forces Windows to regenerate the secure clock files and re-register them with the DRM server.

Note: This requires admin rights. If you're on a work or school computer, you might need IT help.

Open Command Prompt as administrator. Click Start, type cmd, right-click Command Prompt, and select Run as administrator.
Stop the DRM service by typing the following command and pressing Enter:
```
net stop DrmService
```
You should see a message: The DRM Service service was stopped successfully.
Now delete the DRM database folder. Type this and press Enter:
```
rmdir /s /q "%ProgramData%\Microsoft\Windows\DRM"
```
The command runs silently — you won't see any confirmation, which is fine.
Restart the DRM service:
```
net start DrmService
```
You should see: The DRM Service service was started successfully.
Open Windows Media Player. It will rebuild the secure clock and contact Microsoft's DRM server to get a fresh certificate. This might take up to a minute.
Plug in your device and try syncing again.

This almost always works. If it doesn't, there might be a deeper issue with your Windows installation or a corrupted user profile. In that case, try creating a new Windows user account and test the sync there — but that's rare.

One More Thing: Check Your Antivirus

I've seen aggressive antivirus software block the DRM server entirely. Specifically, some versions of Norton and McAfee flag the DRM service as a security risk. If the above fixes didn't work, temporarily disable your antivirus, then try syncing. If it works, add an exception for %ProgramData%\Microsoft\Windows\DRM in your antivirus settings.

That's the whole flow. Start with the clock sync, then reset DRM, then go advanced. Nine times out of ten, the clock sync is your issue. If not, the advanced fix is your hammer — and it hits hard.
