Hi all,
After many weeks of problems with Error 0x80072EFD I found the soloution
through another user of the discussion group. It was in a MS 'fix' for the
problem but I cannot remember which. I've copied the contents of the fix
below.
Just a quick thanks to all of you who offered suggestions, ideas and help...
without which my computer would have been thrown under a bus weeks ago!!!
Hope this helps somebody else.
Robbert

CAUSE
These errors indicate that the Windows Update client did not receive a
response from the Windows Update or Microsoft Update Web site. This may be
causedd by programs that are running on the client computer or by general
network-related failures.

RESOLUTION
To resolve this issue, use Method 1 or Method 2.
Back to the top
Method 1: Home users or users who are not behind a proxy server
Step 1: Verify Internet connectivity
Make sure that you can successfully access other Web sites. If you can
successfully access other Web sites, your Internet connection is working
correctly.
Step 2: Verify your personal firewall program settings
If you have a personal firewall program installed, you might have to
reconfigure or update the personal firewall program. The Windows Update
client and the Microsoft Update client run in an instance of Svchost.exe.
This Svchost.exe instance requires access to the Internet. For more
information about how to reconfigure or update your firewall program, see the
documentation that was included with the program, view the Help files for
your program, or contact the program vendor. For information about how to
contact the program vendor, click the appropriate article number in the
following list to view the article in the Microsoft Knowledge Base:
65416 (http://support.microsoft.com/kb/65416/) Hardware and software vendor
contact information, A-K
60781 (http://support.microsoft.com/kb/60781/) Hardware and software vendor
contact information, L-P
60782 (http://support.microsoft.com/kb/60782/) Hardware and software vendor
contact information, Q-Z
To troubleshoot and ensure any Firewall Programs you have running are not
interfering with windows update try the following steps.
Important Before you disable the firewall for troubleshooting, turn on the
Windows XP Internet Connection Firewall. To do this, follow these steps: 1.
Click Start, click Control Panel, double-click Networking and Internet
Connections, and then click Network Connections.
2. Right-click the connection on which you want to turn on the Internet
Connection Firewall, and then click Properties.
3. On the Advanced tab, click the box to select the option to protect my
computer or network.
Temporarily disable your Firewall program and see if you can now access the
Microsoft Windows Update Website. Even though you may have had a Firewall
running for some time without any previous problems, new updates to the
firewall program may create issues.
Step 3: Add the Windows Update Web site and the Microsoft Update Web site to
the Trusted Sites list
Add the Windows Update Web site and the Microsoft Update Web site to the
Trusted Sites list in Internet Explorer. To do this, follow these steps: 1.
Start Microsoft Internet Explorer.
2. On the Tools menu, click Internet Options.
3. Click the Security tab, and then click Trusted Sites.
4. Click Sites, and then click to clear the Require server verification
(https:) for all sites in this zone check box.
5. In the Add this Web site to the zone box, type the following addresses,
clicking Add after you type each address: • http://update.microsoft.com
• http://download.windowsupdate.microsoft.com
• http://update.microsoft.com/microsoftupdate/v6/default.aspx
6. Click OK two times.
Step 4: Remove entries for Windows Update and Microsoft Update from the
hosts file
Some programs may modify the hosts file to control DNS name resolution.
Sometimes, an entry for the Windows Update Web site or for the Microsoft
Update Web site may exist in the hosts file. To remove these entries from the
hosts file, follow these steps: 1. Click Start, click Run, type notepad
%windir%\system32\drivers\etc\hosts, and then click OK.
Note If you are prompted to choose a program to open the hosts file with,
click Notepad, click to select the Always use the selected program option,
and then click OK.
2. In Notepad, configure any lines in the hosts file that contain entries
for Windows Update so that they are not read when the file is accessed. To do
this, place the number sign (#) in front of any line that contains
"microsoft" and "update." For example, add the number sign (#) to the
beginning of the following entries: • # 64.4.21.125
http://update.microsoft.com
• # 64.4.21.125 http://windowsupdate.microsoft.com
3. Remove any lines that contain entries for Windows Update or for Microsoft
Update. For example, remove the following entry if the entry exists:
http://update.microsoft.com
4. On the File menu, click Save.
5. Exit Notepad.
6. Restart the computer.
Note If you do not want to restart the computer, you can also flush the DNS
resolver cache. To do this, follow these steps: a. Click Start, click Run,
type cmd, and then click OK.
b. At the command prompt, type ipconfig /flushdns, and then press ENTER.
Step 5: Remove the proxy server entry from the WinHTTP proxy configuration
If you are not located in a corporate network, or if you do not use a proxy
server to connect to the Internet, clear the WinHTTP proxy configuration. To
do this, follow these steps: 1. Open Internet Explorer.
2. On the Tools menu, click Internet Options.
3. Click the Connections tab, click LAN Settings, and then click Advanced.
4. In the Local Area Network (LAN) Settings dialog box, click to select the
Automatically detect settings check box, and then click OK.
5. Quit Internet Explorer.
6. Click Start, click Run, type cmd, and then click OK.
7. Type the following commands. Press ENTER after each command. a. proxycfg
-d
b. net stop wuauserv
c. net start wuauserv
d. exit

Method 2: Corporate users or users who are behind a proxy server
If you use a proxy server to connect to the Internet, see the following
Microsoft Knowledge Base (KB) article for information about how the Windows
Update client detects and uses proxy servers:

client determines which proxy server to use to connect to the Windows Update
Web site
