C80003F3 - Resolution Suggestion One:

In most cases you can resolve this error by doing the following, however it is not for "newbies" so you may need a "tech" friend to do it for you. (and please note that there other ways to do this, but this is the way I would do it... so no sending me emails!)

Step 1

First register you will need to register the following files:

In Windows XP go to the Run item on the Start menu, and type:

In Windows Vista go to the Start Search box on the Start Menu, and type:

 
regsvr32 MSXML3.dll /s
 
net stop wuauserv
 
cd /d %windir%\SoftwareDistribution
 
rd /s /q DataStore
 
net start wuauserv


Step 2

This "may" result in any/all of the following errors in WindowsUpdate.log:


0x80240013
0x8024400a
0x80240017


Step 3

So you will need to register the following system files too...

In Windows XP go to the Run item on the Start menu, and type:

In Windows Vista go to the Start Search box on the Start Menu, and type:



regsvr32 softpub.dll

regsvr32 initpki.dll

regsvr32 mssip32.dll



Step 4

You may also receive the following errors in your WindowsUpdate.log don't panic!


0x80070008
0x80240017

(if you have never heard of this log file then you need to read this.)


Step 5

Finally, you will need to performed the following:


1) Stop the Automatic Update/Windows Update service.

To do this in Windows XP go to the Start Menu --> Control Panel --> Performance and Maintenance --> Administrator Tools --> Services --> Double Click "Automatic Updates Service" --> On General Tab for this service select the STOP button under Service Status.

To do this in Windows Vista go to the Start Orb --> Control Panel --> Administrative Tools --> Services --> Double Click "Windows Update Service" --> On General Tab for this service select the STOP button under Service Status.


 2) Rename the SoftwareDistribution folder in C:\Windows to SoftwareDistribution.old

3) Start the Automatic Update/Windows Update service. (...use the instructions in no.1) above.

 

...and that should have now resolved the C80003F3 error for you!
