1. Make sure you are logged in as an Administrator (if you are not the
Administrator, then log in as an Administrator and try Windows Update
again).
2. Make sure your firewall is not blocking the Update site and check any pop
up stopper programs.
3. Now check in IE tools\manage add-ons (Win XP SP2 only) making sure that
WuWebControlClass is enabled. (Select "Add-ons that have been used by
Internet Explorer" in the "Show:" drop down list)
4. You may also wish to check c:\windows\Downloaded Program Files to see if
anything is corrupted there.
5. Make sure you accepted the Microsoft Trust Certificate

REGSVR32 wuapi.dll
REGSVR32 wuaueng.dll
REGSVR32 atl.dll
REGSVR32 wucltui.dll
REGSVR32 wups.dll
You should receive a successful message after each one.
Try Windows Update Again.
If that hasn't helped you may need to re-register some more files:-
net stop cryptsvc
regsvr32 softpub.dll
regsvr32 wintrust.dll
regsvr32 initpki.dll
regsvr32 dssenh.dll
regsvr32 rsaenh.dll
regsvr32 gpkcsp.dll
regsvr32 sccbase.dll
net start cryptsvc
You should receive a successful message after each one.
If necessary:-
Re-install Windows Update files
http://download.windowsupdate.com/v6...gent20-x86.exe
Note If you have an x64-based computer, visit the following Microsoft Web
site:
http://download.windowsupdate.com/v6...gent20-x64.exe
Click Save in the File Download-Security Warning dialog box, and then select
the location where you want to save the file.
Double-click the file that you saved
NB - A note from Torgeir Bakken [MVP]
Note that if it says "Install is not needed since Windows Update Agent is
already installed.", run the exe with the command line switch /wuforce, like
this:
WindowsUpdateAgent20-x86.exe /wuforce

| For the past few days every time we try to use Windows update on Wndows XP
| sp2, we recieve the error message "0x8DDD0004." We have gone through all
the
| reccomended steps on the Microsoft update help site but still no luck, and
| the support centre does not offer solutions for Windows XP. The automatic
| update is turned on but we have had no updates for months. Can anyone
suggest
| anything?
| Thank you.
