SYMPTOMS

After you uninstall Microsoft Windows Server 2003 Service Pack 2 (SP2) or Microsoft Windows XP 64-Bit Edition Service Pack 2 (SP2), Microsoft Windows Media Player cannot play media files that are licensed by using Digital Rights Management (DRM) technology. Existing licenses do not work correctly, and you cannot acquire new licenses. Additionally, you receive the following error message:
Windows Media Player cannot play, synchronize, or burn a protected file because an error occurred while verifying the license. (Error code 0xC00D11DA)
This problem also occurs in third-party applications that use the Windows Media Format Software Development Kit (SDK) runtime.

CAUSE

This problem occurs because the DRM components that are used to store licenses in Windows Server 2003 SP2 and in Windows XP 64-Bit Edition SP2 are not backward compatible with earlier service packs.
