Windows Update Fails with Error Code 80071A91
Hi,
All Windows automatic updates have been failing since 2015-11-12. The last successful update was the Windows Malicious Software Removal Tool x64 - November 2015 (KB890830) on 11/12/2015 03:17. The first failed update since then was Security Update for Windows 7 for x64-based Systems (KB3100213) on 11/13/2015 20:25.
Manual installation of the pending updates does not work. Reboot does not install the pending updates either. Another symptom was that Windows was no longer detecting my third party Anti-Virus software. I removed and reinstalled the software thinking it might be related and Windows started detecting the Anti-Virus software again but I can no longer access the computers from other computers on my home network. For now let's focus on the Windows problem which may be hardware failure induced--hardware crash/power cycle without a Shutdown.
System details are as follows:
Symptoms and troubleshooting to date indicates I have an intermittent hard drive failure. It appears that one of the two drives needs to be replaced. Dell boot diagnostics reported a hard drive error code 2000-0142 and one drive has dropped out of the array a couple times the last three months. A rebuild both times corrected the problem. Currently, the Intel Rapid Store Technology application is reporting the array as good but I am experiencing extremely sluggish performance. Internet Explorer appears particularly slow and it's not my ISP.
- Dell XPS 420 Desktop
- Windows 7 Home Premium 64 bit, SP1
- Intel Core2 Quad CPU Q6600 2.4 GHz
- 8 GB of memory
- nVidia GeForce 8800 GT
- Generic Sound (on motherboard)
- Intel RAID 1 volume with two Seagate Barracuda ST1000DM003-9YN162 1 TB SATA Hard Drives
- Dell KM632 Wireless Keyboard and Mouse
- McAfee Internet Security Suite
- Internet Explorer 11
I'd like to get this software issue resolved so I can replace the hard drives in the array. With a RAID 1 mirrored array, Intel Rapid Store Technology with allow me to replace the hard drives one-by-one and rebuild the volume without having to reinstall my software or restore from backup. I also have some ham radio hobby related programs installed that aren't the easiest to reinstall.
I've run the System Update Readiness Tool and SFC /SCANNOW. My CBS.LOG file is attached as Part 1 and Part 2 (it exceeded the 8 MB limited so I split it in two). I only included the log file. Zipped, the CBS folder in still over 100 MB in size. Which is a bit worrisome.
Any help would be appreciated.
Regards,
Mark
