The error 0x800B0003 occurs in your Windows Update.log due to mismatch in digital signature. This issue can be fixed by enabling "use http 1.1 through proxy connections" in Internet Options.

To enable "use http 1.1 through proxy connections"

1. After Opening Internet Explorer click Tools / Internet Options.
2. Click the Advanced Tab.
3. Remove the check from use HTTP 1.1
4. Place a check in Use HTTP 1.1 through proxy connections.
5. Attempt to access the Windows Update site again.
6. If you are still experiencing difficulties with the update site, try having both HTTP 1.1 and HTTP 1.1 through proxy connections checked.”

Hope it Will help you

There are several potential causes for this error. First of all, make sure you are running the current version of Internet Explorer. At this time, the current version is IE 6 SP1. You can install IE 6 SP1 from this link:

http://www.microsoft.com/windows/ie/...p1/default.asp

Secondly, if you are using a proxy server ask your network administrator to make sure that the proxy server is set to allow anonymous connections to the Internet.Some more specific steps you can try to resolve this issue:

Register the following files with these steps:

1. Click on Start, Run and type "REGSVR32 SOFTPUB.DLL" (w/o the quotes). You should see a popup message that this process succeeded.
2. Click on Start, Run and type "REGSVR32 INITPKI.DLL" (w/o the quotes). You should see a popup message that this process succeeded.
3. Click on Start, Run and type "REGSVR32 MSSIP32.DLL" (w/o the quotes). You should see a popup message that this process succeeded.
4. Now try the Windows Update site and see if you get the same error.

It is likely that a component of the Windows XP digital signatures process is damaged - so lets re-register some DLL files. sounds like fun, eh? Onwards and upwards!

1. Click Start menu, and then click the Run icon.
2. In the small box that Opens, type the three letters: cmd then click the OK button.
   
   
3. In the command prompt window that just opened (a black background and white text), type the following commands, pressing the ENTER key on your keyboard after each line:
   
   • net start cryptsvc
   • regsvr32 softpub.dll
   • regsvr32 wintrust.dll
   • regsvr32 initpki.dll
   • regsvr32 dssenh.dll
   • regsvr32 rsaenh.dll
   • regsvr32 gpkcsp.dll
   • regsvr32 sccbase.dll
   • regsvr32 slbcsp.dll
   • regsvr32 cryptdlg.dll
4. Now type the word: exit and the window will close. Now Reboot and try and reply the Microsoft Patch again...
   
5. Reboot your machine and try Windows Update again. This should now cure your 0x800B0004 error message problem...

Hello , If there is a HOSTS (or HOSTS.SAM) file on your system that has an entry for the Windows Update site, then comment out or delete the entry. The IP addresses of the site change constantly so you don't want to have any static IP entries.
