Windows Defender was unable to complete the update: 0x8024400a

Say more about the network you are on--is it a large managed network with a
WSUS server?

Are you having any trouble with Windows Update or AutoUpdate?

Terrific--sorry about the cryptic nature of the query--Windows Defender has
somewhat different update strategys depending on the network infrastructure
available to it. I can't tell from the average post here whether the user
is on a large corporate network or a small home network.

I'd like to here what the solution to the problem was. I have a customer
that is having the same problem. The customer is on a small SBS based
network using the default SBS firewall (not ISA) and is receiving the error
0x8024400a. (this everytime that Windows Defender tries to update, either
automatic or manual)

Funny thing about this is that his configuration matches my own very
closely. Windows Defender works just fine on my computer. (although, I do
wish there was an option to show it in the system tray).

In any case, I'd love to know of a solution to this problem.

I'd like to hear myself. I've got a few dozen machines on SBS-2000
networks, using ISA-2000 firewalls.

I found that on a few machines it was necessary to change the "automatically
detect" setting for proxy server detection--the oddity was that on one
machine I turned it off, whereas on two others, I turned it on--all on the
same network behind the same transparent proxy setup.

An SBS customer might also be running WSUS, and if they are, Windows
Defender will be looking for the signature updates from WSUS--and they are a
new class of update that the admin must enable.
