It could very well be a hijackware infection.
Please update your anti-virus and run a full scan of the computer.

Also check your Event/Application logs in system tools.
Could be something that is causing interferance such as firewall.
Post log or explain what you see.

All searching seems to pint to some malware - or your simply failing Windows Validation.

Run the Microsoft Malware removal tool - then run through this http://www.petenetlive.com/KB/Article/0000183.htm

then check validation http://www.microsoft.com/genuine/

hi you
1. check internet connection -->OK
2. turn off firewall before you update to prevent lost connection.

regards

Also stop the automatic update service (Start > run > services.msc {enter}
Delete c:\windows\softwaredistribution
Then restart the service again  - then re-attempt the windows update

- do you have an upstream proxy server? is the browser set to use Http 1.1? also try 1.1 through proxy

see http://www.webreference.com/internet/software/servers/http/compression/ie5.gif

Try the BITS repair tool http://support.microsoft.com/kb/971058

if you have a proxy settind leased by WPAD see my website here for details http://www.petenetlive.com/KB/Article/0000181.htm
then this can cause the problem also http://www.tech-archive.net/Archive/Windows/microsoft.public.windowsupdate/2004-10/1330.html

Here is what that error means
BG_E_MISSING_FILE_SIZE
0x80200011
When BITS sends a HEAD request and the server/proxy does not return Content-Length header in the response, BITS puts the job in ERROR state with this error. Check the proxy server and WSUS server to ensure that they are configured correctly. Some versions of the Apache 2.0 proxy server are known to exhibit this behavior.
