Windows Update Error Code 8020002E

The error code indicates connection problems rather than anything else - let's have a look at some of the other logs.

Please upload the C:\Windows\Windowsupdate.log file


Open Event Viewer
click on the Windows logs entry in the left pane to expand it.
Now click on the Application entry - wait while it loads.
Click on 'File' in the menu bar and select Save...
Save the file as Appevt.evtx
Repeat for the System log
then zip both, and upload them.

• The System log shows the following problems (amongst others)
• the CWDaemon service is failing
• SChannel eventid 36887 (Alert 0) - TLS1_ALERT_CLOSE_NOTIFY
• The server {D3F6D4DB-A482-4648-8DBB-3565EBCB7A6B} did not register with DCOM within the required timeout.
• The server {F9717507-6651-4EDB-BFF7-AE615179BCCF} did not register with DCOM within the required timeout.
• The application-specific permission settings do not grant Local Launch permission for the COM Server application with CLSID

{C97FCC79-E628-407D-AE68-A06AD6D8B4D1}
and APPID
{344ED43D-D086-4961-86A6-1106F4ACAD9B}

The Applications log shows errors from
Bonjour (iTunes etc)
MobileMServices
JNBDotNetSide.exe (.NET)
MotoHelperAgent.exe

You may want to review which of these you want/need to keep installed.

I can only find this error now - all others appear relatively minor...

This appears to relate to the IpBusenum.dll file/service.

Unfortunately, this is one of those errors where the related KB article is very little use
Event ID 10016 ? COM Security Policy Configuration

The best I can come up with it this...
Please open an Elevated Command Prompt, and run the following commands.

REG QUERY HKLM\SYSTEM\CurrentControlSet\Services\IpBusEnum
REG QUERY HKLM\SOFTWARE\Classes\AppID\{344ED43D-D086-4961-86A6-1106F4ACAD9B}
REG QUERY HKCR\AppID\{344ED43D-D086-4961-86A6-1106F4ACAD9B}
REG QUERY HKCR\AppID\IPBusEnum.DLL
REG QUERY HKCR\CLSID\{C97FCC79-E628-407D-AE68-A06AD6D8B4D1}

post the results, and we'll see what I can see

You could have put all of them in a code box, or in a Notepad file - and compressed it - and it should have come out less than 10KB :)
I should have posted my usual instruction set...


Here are some instructions to make life easier :)
1) To open an Elevated Command Prompt Window (the ECP window), click on Start, All Programs, Accessories – then right-click on Command Prompt, and select Run as Administrator. Accept the UAC prompt.
2) To run the commands easier, highlight the block of commands, and right-click on the highlight – select Copy. In the CP Window, click on the black/white icon at top left – select Paste. The commands will run but may not complete the last command, so hit the Enter Key once.
3) To copy the results... click on the Black/White icon in the top left, and select Edit... 'Select All', and hit the Enter key - then use Ctrl+V or r-click+Paste to paste it into your response.

...anyhow - back to what you found...

All of that looks fine to me - or at least it's the same as on my machine.

I'm not sure where to go next...
Ah - I can't see the C:\Windows\Windowsupdate.log file I asked for?

There's a couple of error there that make me think that the download control is corrupted. I think we need to clear the SoftwareDistribution folder.

You will lose your Update history (but the updates will still be installed, and viewable in the Installed Updates listing).

Open an Elevated Command Prompt
Run the following commands

NET STOP WUAUSERV
REN C:\WINDOWS\SoftwareDistribution SDOLD
NET START WUAUSERV

reboot
then wait 10 minutes, and open Windows Updates, and run a Check for Updates.

Install only the oldest update found - and reboot once installed
then go back to Windows updates and install the others.
