Recent issues have been seen where you might get 3 specific errors on different Windows-based computers when trying to download or install updates from Windows update or Microsoft Update. Some of these errors messages are:

On Windows 2000, Windows XP and Windows server 2003

“Windows Update has encountered an error and cannot display the requested page. The necessary service "Automatic Updates" (WUAUSERV) is not started or Background Intelligent Transfer Service (BITS) is disabled. “Error 0x8DDD0018

On Windows Vista and Windows Server 2008

“The server cannot find the requested URI (Uniform Resource Identifier)” Error 0x80244019

-Or-

“The service cannot be started, either because it is disabled or because it has no enabled devices associated with it.” Error 0x80070422

You might attempt to restart the start the services but they may be disabled again the next time you rebooted the computer. You may simply not be able to start others.

INTRODUCTION

The error codes above are usually caused because of problems with one or more of the services needed by Windows Update. The services could have been mistakenly stopped or disabled or they could have been disabled by Virus or Malware infections. Some of the scenarios that lead to these errors can include disabling the Automatic Update service, the Windows Update service, the Event Log service, the Software Licensing Service or even the Background Intelligent Transfer Service (BITS). The services can even be in a state where you’re not allowed to enable the service or the service is disabled again each time you reboot.

APPLIES TO

These issues apply to the following operating systems:

Windows Vista, Windows Server 2008, Windows XP, Windows Server 2003, and Windows 2000 Service Pack 4

Here are some options available for doing this:

Download and run the Malicious Software Removal Tool (MSRT):

Reboot your computer into Safe Mode and then scan your system for possible Virus or Malware infections:
