Windows Server 2012 Windows Update Error 0x80240440

I have begun setting up a new server for a branch office, and have decided to use Windows Server 2012 on it; thanks Software Assurance! This way I can utilize the new Hyper-V features when I’m ready, as well as virtualize a domain controller properly.

 

However, I ran into a problem with Windows Update on both the Host and Guest running Server 2012. Windows Update reported an error:

 

 

The windows update log located at %windir%/windowsupdate.log reported this:

At first I thought this may be related to the “Trusted Sites” within Internet Explorer. I have mine set through GPO, so I added “https://*.update.microsoft.com” to that GPO and then did a “gpupdate /force”, but the error remained.

 

Then I thought to look at my Sonicwall NSA 2400; we have the Application Control enabled, and this has been known to cause strange network connectivity issues even when not expected so I’ve just by default started checking here.

Unsurprisingly this turned out to be the problem. The strange thing is, the AppControl rule that was blocking the traffic isn’t visible in the list of applications; only through the logging did I find it.
If you navigate to the AppControl settings page, use the “Lookup Signature”, for signature # 6:

 

Click on the pencil icon, and you’ll see this screen:

 

Turns out the rule “Non-SSL Traffic over SSL port” is blocking this Windows Update traffic.

Setting the Block option to Disabled for this rule allows Windows Update to work properly.

  1. I was having no luck finding the problem, but your post helped me find the same issue in my ips settings for my nsa 240. Thanks a million!

  2. For me it was (and is) the Checkpoint SSL extender software that starts similar problem

    Checking Internet Options > Connections > Lan Settings and leaving only Auto detect option, internet connection in gone. only when changing to proxy (and entering whatever i want (aka: bla bla bla) Internet is back… but some windows store applications won’t install with error 0×80240440.

    Happens on Win 8 Pro (RTM)

  3. @Reuben, any help that I could offer would require much more information from you on your situation. Have you checked the Windows Update log in the path I’ve mentioned above?

  4. This worked like a charm! Didn’t even think about our router settings… primarily because we’ve never seen behavior like this before Windows Server 2012 was introduced to our environment.
