Fix NS_E_FEATURE_REQUIRES_ENTERPRISE_SERVER (0XC00D1583) on Server 2003

This error pops up when a plugin needs Windows Server 2003 Enterprise Edition but you're running a standard or web edition. The fix is to either upgrade or use a workaround.

When This Error Hits

You'll see NS_E_FEATURE_REQUIRES_ENTERPRISE_SERVER (0XC00D1583) when trying to load a plugin in Windows Media Services (WMS) on a Windows Server 2003 box that isn't Enterprise Edition. I've seen it most often with third-party streaming plugins or Microsoft's own cache/proxy plugins. You're running WMS, add a new plug-in, and boom—error message, plugin doesn't load.

Root Cause

The culprit here is almost always the server edition. Some WMS plugins were written to only run on Windows Server 2003, Enterprise Edition. They check the OS version at load time. If you're on Standard or Web Edition, they refuse to start. Microsoft locked certain features (like advanced caching or multicast) to Enterprise only back in the day. No registry tweak or service restart will bypass this—it's a hard-coded check.

The Fix

You've got two real options. Don't bother with searching for a patch or hotfix—there isn't one for this error. Here's what works:

Option 1: Upgrade the Server Edition

  1. Check your current edition: Go to Start > Run, type winver. If it says Standard or Web, you're stuck.
  2. Upgrade to Enterprise Edition: Insert the Server 2003 Enterprise CD, run winnt32.exe /unattend for an in-place upgrade. This keeps your settings.
  3. Reboot and try loading the plugin again.

Option 2: Replace the Plugin

  1. Find out which plugin is failing. Check the WMS logs: %windir%\system32\LogFiles\WMS.
  2. Search for a Standard Edition compatible version of that plugin. Some plugins had separate builds for different editions.
  3. Uninstall the old plugin, install the new one, restart WMS.

What to Check If It Still Fails

If the error persists after upgrading:

  • Confirm the upgrade took: Run winver again. I've seen upgrades silently fail if the CD doesn't match the language or service pack level.
  • Check service pack: The plugin might need SP1 or SP2. Install the latest service pack for Server 2003.
  • Verify WMS version: Run netsh wms set status in command prompt. If it shows version 9.0, you're fine. Anything older? Update via Windows Update.
  • Test with a basic plugin: Load the WMS built-in "WMS HTTP Download Data Source" plugin. If that works, the issue is specific to the third-party plugin.

One last thing: If this is a VM, make sure you gave it enough RAM (minimum 512MB). Enterprise Edition checks for resources at load time too. Low memory can trigger false positives.
