Hello,
A search of this group finds this response from Lucy Eby.

What proxy are you running?
Error 0x80072F78 - Invalid Server Response this is typically due to proxy.

Try the following:
Check connection settings:
Open Internet Explorer
Select Tools > Internet Options > Connections > LAN Settings
Check or uncheck the "Automatically Detect Settings" option.
Apply changes, exit Internet Explorer then try Windows Update again.

Henry / Maurice I have updated both my laptop and my home PC to XP SP 2 and I
am getting the same error message on both my machines when trying to run
Windows Update. My company use a Proxy server and all machine are configured
via an automatic configuration script file ( .pac file) All internet access
is working except the Windows update. Any ideas?

Hello Johan,
Seeing that you have XP SP2 --- I'd suggest that you try the following:

In Internet Explorer browser > main menu /Tools / Internet Options >

Security Tab/ click on green icon Trusted Sites/click Sites button.

Look very closely at line that says: "Require server verification (https for all sites in this zone" to *clear* the selection.
(e.g. You want that to be clear or un-checked (un-ticked)).

In the "Add this Web site to the zone:" field, add these entries to list of "Trusted Sites" --

type
http://*.windowsupdate.com (click Add)

http://*.windowsupdate.microsoft.com

https://*.windowsupdate.microsoft.com (with HTTPS)

http://windowsupdate.microsoft.com


Click OK.
Apply changes, then try Windows Update again.
