Update_dt000 Windows and error code oX80072efe

Seven days ago (15/11/2010), I am unable to check the updates of Windows. I get the following message: Windows Update_dt000 and error code 80072efe. I can't update the my virus definitions, malware and software Microsoft Essentials spies either. I scanned my computer with Microsoft Security Essentials and McAfee, and no viruses or malware were detected. * I downloaded manually the latest definitions to Microsoft Security on 11/22/2010. Even after the last definitions of installation, I was unable to automatically check for updates. Help, please!
