Error

Finding a solution for the 0x8024402c error
|
|
|
This is a fairly
common Windows Update error and hopefully this article will help you
resolve the problems you are having.
The 0x8024402C error
code
typically occurs because an incorrect character exists in the
proxy override settings.
But there are some
other reason and these are listed below.
|
What causes Error
0x8024402c
# Incorrect character exists in the proxy
override settings.
#
A misconfigured Proxy/Firewall can cause this problem.
#
You are trying to access Windows Update using VPN. The website and
Automatic Update may not function properly.
#
The corporate environment does not have autoproxy implemented.
# Your
workstations sit behind a Microsoft ISA server.
To try and resolve
the error 0x8024402c, use the following tips... After each tip test
to determine whether the issue is resolved.
Resolution Suggestion One:
#
Remove invalid characters from the proxy
exception list and then clear the proxy cache.
1. Open Internet
Explorer.
2. On the Tools, select Internet Options.
3. Click on the Connections tab.
4. Click on the LAN Settings.
5. Click on the Advanced button.
6. Please delete any entry in the Exceptions section.
Next, clear your proxy cache.
1. Click on Start, and then click Run.
2. Type cmd in the Open box to get a DOS prompt.
3. Type proxycfg -d at the command prompt, and press
Enter.
4. Type net stop wuauserv at the command prompt, and
press Enter.
5. Type net start wuauserv at the command prompt, and
press Enter.
6. Now try the site again.
-----------------------------------------------
Resolution Suggestion Two:
#
Reconfigure or update your firewall program.
Double-check the Proxy/Firewall settings. Add the
following urls to the exception list within your Firewall/Proxy:
http://*.windowsupdate.microsoft.com
https://*.windowsupdate.microsoft.com
http://download.windowsupdate.com
For help configuring Proxy/Firewall refer to
documentation or contact the manufacturer.
-----------------------------------------------
Resolution
Suggestion Three:
#
VPN and Proxy.
You are trying to access Windows Update using
VPN. The website and Automatic Update may not function properly.
Autoproxy is not picking up the wpad.dat
proxy configuration file to determine the proxy to be used for the
target URL. Thus we are going with no proxy!
1. Try to access Windows Update while not using VPN connection.
2. Use the proxycfg tool to specify a proxy server to use
(proxycfg.exe -p <proxy server>). (contact your network
administrator to find out the name and port of this proxy.)
-----------------------------------------------
Resolution
Suggestion Four:
#
Run proxycfg to tell WU about your proxy.
The corporate environment does not have autoproxy
implemented.
Automatic Update will always do autoproxy
detection and thus if that returns no proxy, it will try to use no
proxy. Use the proxycfg tool to specify a proxy server to use
(proxycfg.exe -p <proxy server>). Please contact your network
administrator to find out the name and port of this proxy.
-----------------------------------------------
Resolution
Suggestion Five:
#
Your workstations sit behind a Microsoft ISA
server...
There appears to be a small issue with the new
Windows Update service that requires both a "Site and Content
Rule" and a "Protocol Rule" in order to process an ISA server's Web
Proxy request.

Other suggestions found in
Newsgroup postings :
# ONE
I was received this error, and I tried all the MS
KB articles, and read through every single thread in this newsgroup
related to Error: 0x8024402C and was unable to fix it. If you read
very carefully in Windows Update, besides the 8024402C error, there
is an error that says "You didn't accept the EULA". Go back and
check! I was unsure what was going on, but I never saw an EULA (End
User License Agreement) Dialogue Pop-up. Until I made the
3 changes below.
This works for sure:
1) BITS (Background Intelligent Transfer Agent); Automatic Updates
and Cryptographic Services *MUST* be enabled (Control Panel,
Administrative Tools, Services). **You can turn them OFF and disable
later if you so desire.
2) Go to "Tools, Interent Options, Privacy, Pop-Up Blocker,
Settings...and made sure the following are added:
*.microsoft.com
*.download.microsoft.com
*.windowsupdate.com
*.windowsupdate.microsoft.com
v5.windowsupdate.microsoft.com
windowsupdate.microsoft.com
3) Go to TCP-IP Properties, Advanced, DNS, and made sure all
defaults are chosen. (Append Primary & Suffix radio button is
checked, everything else is blank) This assumes you are receiving a
DHCP address. Unplug & Plug your Network cable back out & in, so it
gets a new DNS suffix with the DHCP address.
No more Windows Update Errors!

# TWO
This 0x8024402C error was driving me nuts.
One thing that was absolutely bizzarre to me, is that in the log,
not only as many ppl are seeing, is there reference to an attempted
connection by proxy (when ie connection settings are not set to
proxy) BUT the hostname of the proxy matched the hostname that my
server was set to about a month ago (not the current hostname, and
there was never a proxy anyway!) This particular machine was also
never previously connected to this server! My only guess is that MS
is somehow and for some reason keeping some sort of dated reverse
DNS log and directing windows update to use a proxy on that host.
Now for the good part (after a full day wasted.) To resolve the
issue, I set ie to actually use a proxy (one of the free open ones)
and put the exception list in.
Windows update then worked.
I removed the proxy settings, and it worked again.
0x8024402C problem solved. I hope. Still curious about the
cause!
----------------------------------------------------------
# THREE
I had the same problem and found out that it was
due to the Firewall feature of Norton Internet Security. Once this
firewall is turned off, then it works fine. Actually having this
firewall on disabled my Internet Explorer totally!!! But you can
still keep the Windows firewall on (in Control Panel) and no
problem.
I hope it helps you guys as it did to me,
------------------------------------------------------------
# FOUR
I solved the 0x8024402C error by adding a DNS server in my TCP-IP
settings. I guess that most of these errors can be solved this way.
Any way this should be the first and most simple thing to check.
--------------------------------------------------------------
# FIVE
After combing the newsgroups for 2 days and trying everything
mentioned but
to no avail, I decided to just HACK the damn issue myself and well I
found
the fix.
If you are using w2k server and get that damn Error number:
0x8024402C when
using the new Microsoft Update do the following:
1) Navigate to
HKLM\Software\Microsoft\Windows\CurrentVersion\Internet
Settings
2) If you see a connections folder, look inside
and there should be a
default key and a WinHttpSettings key.
3)Export the connections folder and delete it.
(export it so you have a
backup of it)
4) You should now be able to go to Microsoft
Update and scan without seeing
that damn Error number: 0x8024402C .
