Re: 0x8024401B

It means that Proxy access failed or proxy access was denied. This equates to HTTP error status 407.
Basically, proxy authentication is required.

Plain-speak: Are you using a proxy server to access the internet? Are you running some sort of anonymiser program?

Be sure you got/saw this error in your WindowsUpdate.log file.

Try turning off any antivirus program & any user application programs before going to Windows Update, and be sure you are using Internet Explorer browser.

Re: 0x8024401B

See if you have following settings:
In Internet Explorer browser, select Tools >Internet Options > Advanced Tab > (scroll down thru the list)

These are "some" of the items that I have CHECKed (selected):
Under HTTP 1.1 settings --
Use HTTP 1.1 (ON / Selected)
+ Enable / check "Use HTTP 1.1 with proxy servers" **** <<----

Internet Explorer > Tools > Internet Options > Connections Tab Click
on LAN Settings > * Uncheck* the Automatically detect settings.
Make sure _no other_ settings on this screen are enabled.

Re: 0x8024401B

I got this same error on my Windows 2000 Server (SBS, actually).
I'm running ISA Server.
More and more software seems to not work with ISA Server (which is a
firewall/proxy/caching server), including MSN Investor (the ActiveX portfolio
control), the new www.Trumba.com Outlook sync application, and now Windows
Update.

It would appear that Microsoft is no longer supporting ISA Server?

I've been having the same problems, I applied this security update to my ISA
server - http://www.microsoft.com/technet/sec.../MS05-034.mspx
and windows update seems to be working fine now...

Re: 0x8024401B

Thank you for your response, and shedding more light on that situation. ;)

To our other readers & posters: Please DO specify your Windows version / edition, most especially if you have a server.

Re: 0x8024401B

That security bulletin encourages the installation of KB899753.
I installed that, and web browsing essentially stopped working for me! Ouch!
I uninstalled that KB so I could get web browsing working again!

Re: 0x8024401B

It might be a coincidence. That same symptom has been attributed
to the Google toolbar (or perhaps other third-party toolbars).
If you have that product you could try uninstalling it and see if your symptoms
change and if the patch you removed could then be reinstalled.

Are you disallowing anonymous logon through your proxy?
There are some workarounds for getting updates documented here:

You cannot download updates when you access the Windows Update
Web site from a Windows XP-based computer that is behind a firewall
or a proxy server</title>
http://support.microsoft.com/?kbid=896226

(MSN search for
(0x8024401B OR 8024401B) site:microsoft.com
)

See also KB885819 which that page links to.

Re: 0x8024401B

I'm trying to update a Windows 2000 professional PC and getting the same
message. We are using an ISA server and are behind a firewall. I am able to
udpate all the PCs but this one. Why can't I update this one PC when I can
update every other PC (we have over 100)?

Re: 0x8024401B

Well this sucks. :(

Large Corporate network, we MUST use Authenticated Proxies. Have over 2,000
XP Clients, 2003 EE Servers, and 2000 AS Servers, all running Windows Updates
with a local WSUS Server, no problems what so ever.

A week ago, one 2000 AS Server started giving this silly proxu error, now I
sit with three 2000 Servers doing exactly the same.

This is NOT a proxy issue - why would only 3 clients out of more than 2,000
all of a sudden fail???

I've been reading up on this for well over a week now, tried everything that
has been suggested, nothing works... A fix would be appreciated!

Re: 0x8024401B

I have 12 workstations. These are behing our corporate firewall maintained by
our corporate centre. I have no idea how its set up or which product they are
using.

I have persistently received this error on only 2 of our XP workstations.
After checking history on a couple of close error numbers I entered the
following in my pop up blocker settings

*.update.microsoft.com
download.windowsupdate.com

One of the workstations immediately worked and downloaded required updates.
The downside is that the second workstation didn't.

I then checked this site and found a suggestion which I haven't been able to
find again.

This was to enable Tools/Internet Options/Advanced/HTTP 1.1 settings/Use
HTTP 1.1 through proxy connections.

My second workstation then worked for the first 5 updates, but then failed
on 6 thru 21. At least I got some downloaded and installed and I'll try again
on my next visit.

Hope this helps someone!

Yep, the moment I stopped using the ISA proxy, I was able to get the updates.
