Windows Server 2008 R2 - Windows Update error "WindowsUpdate_80070570" "WindowsUpdate_dt000"

I have been wrestling for the last few months regarding what seems to be a common problem all over the world. I have scoured the Internet for answers/suggestions but none seem to work. While I am able to manually download and install failed updates, the reason behind the original failure message is elusive.

I have tried:

Resetting Windows Update Components

Running the System Readiness Tool

Verified the time on the computer is correct

Deleting contents of C:\WINDOWS\SoftwareDistribution\Download

Running System File Checker (sfc.exe)

Moved the computer to another network without proxy/filter

Nothing has resolved the issue.

I decided to build a test environment to attack this problem. I installed a fresh instance of Windows Server 2008 R2 Standard in a virtual machine and began applying ONLY Important updates via Windows Update. Initially, there were 120+ updates to be installed. Many rounds of updates went without issue. There seems to be something that is eventually installed which causes this experience. At this time, the following updates will not install, failing with error code 80070570 "Windows Update encountered an unknown error.":

Cumulative Security Update for Internet Explorer 9 for Windows Server 2008 R2 x64 Edition (KB3049563)

Security Update for Microsoft .NET Framework 3.5.1 on Windows 7 and Windows Server 2008 R2 SP1 for x64-based Systems (KB2972100)

Security Update for Microsoft .NET Framework 3.5.1 on Windows 7 and Windows Server 2008 R2 SP1 for x64-based Systems (KB2972211)

Security Update for Windows Server 2008 R2 x64 Edition (KB2621440)

Security Update for Windows Server 2008 R2 x64 Edition (KB2685939)

Security Update for Windows Server 2008 R2 x64 Edition (KB2864202)

Security Update for Windows Server 2008 R2 x64 Edition (KB2984972)

Update for Windows Server 2008 R2 x64 Edition (KB2990214)

Using the "Get help with this error" link, Windows Help is launched and directed to search with the following string: "WindowsUpdate_80070570" "WindowsUpdate_dt000"

At this point, I believe I will start (again) with a fresh installation and install updates in small batches in an effort to locate the offending update (if that is truly the problem).

I would greatly appreciate any comments, suggestions, etc. that ARE NOT those that I have previously tried.

Thanks in advance!
