I have recently gone back to using Windows 2000 Professional after being non too impressed with XP and have recently installed Service Pack 3. When I run Windows Update, it confirms that there are updates to be installed, but when they are selected and the download button is pressed the following message appears " Windows has encountered an error and cannot display the requested page" error code (0x800A138F). Has anybody else encountered this error since installing SP3?, if so does anybody know how to fix it. I have included a screen dump image of the error. Thanks.
