The Windows 0xc80003f3 bug has been resolved

This is one of those weird, boring problems I have to deal with. This server is one of my lab servers that was built with an automated build. It is a Windows 2008 R2 SP1 based server with TMG 2010 SP2 installed as a reverse proxy. This server was a bit “undisciplined” and “interesting things” happened when a reboot was done to flush out the gremlins. It kept going and working.

After the last patch on Tuesday, I couldn’t get the server to check for updates. Many bugs appeared in the Windows Update client. The data below is taken from the WindowsUpdate.log file, and you can see how varied the errors are. To keep one of my older friends happy, yes, it’s you, Desert Charles, let’s use findtr to analyze the log for a specific phrase:

Findstr.exe /i /c: “Warning: exit code =” WindowsUpdate.log

Using Excel, the error list has been subtracted :

  • WARNING: Output code = 0x80244023
  • WARNING: Output code = 0x80072EE2
  • WARNING: Output Code = 0x8024D011
  • WARNING: Abort Code = 0x8024001B
  • WARNING: Output Code = 0x800401FD
  • WARNING: Output Code = 0x8007000E
  • WARNING: Output Code = 0xC80003F3
  • WARNING: Output Code = 0x8024402F
  • WARNING: Output Code = 0x80080005

Error codes are everywhere, so there is no single point in the WU client that explains them all.

Windows Update Error – This error message may be caused by a Windows Update error. If this scenario applies, you should be able to resolve the issue with the Windows Update diagnostic assistant to identify the problem and automatically apply a viable repair strategy.

Damaged SoftwareDistribution folder – An incomplete update or a file loaded only partially can corrupt an update in such a way that it triggers that particular error code.

Some critical EU services are disabled – Another possible cause of this problem is that some services that are necessary for the WIndows update process are disabled.
