Vista update error 8024402C

Computer Aid Posted on by

This customer had just changed ISP, but wants me to setup the modem.

I figure this should be easy (famous last words 🙁 ).

After a few hiccups with the ISP username, I quickly manage to get the PC back onto the internet (it was off the net for about 3 weeks).

I start doing the antivirus updates, but the vista/defender updates don’t work.

Looking on the net I find a few possible answers:

– turn on network discovery

– antivirus is blocking update downloads

I eventually find the answer when I see someone mention disabling the norton firewall…

This PC is using the Vista firewall… but in the past, I have needed to set the XP firewall back to its default settings.

So I do the same with the vista firewall, and that fixed the problem.

While writing this post, I have a Homer d’oh! moment. I’ve already solved this problem before, and I’ve already written about it at:

D’OH D’OH D’OH!

vista update code 8024402C and windows defender 0X8024402F

A customer had just purchased a brand new acer PC. They had just got it out of the box, but didn’t feel comfortable with the vista setup. And they also needed me to setup their new ADSL internet.

Everything goes smoothly, except when windows defender updates, it generated an error 0x8024402F.

I try windows update, and I get a very similar error: 8024402C

From experience, I know that a windows restart usually fixes defender errors, but not this time.

A quick search reveals that one option is that the internet connection is being blocked, usually by a firewall.

Well, the only firewall on the system is the vista firewall.

I disable the vista firewall, and then both updates work correctly.

After the updates, everything seems to fall into place, and vista is working normally again (even after the firewall is re-enabled).
