Windows Update Woes

Yesterday, I formatted my laptop and re-installed WinXP. I applied SP2 and installed NAV 2003. But then I end up not able to perform Windows update. WindowsUpdate.log shows download failed for some crucial *.cab files which really puzzled me. HOSTS file is not tampered but then I just cannot contact windowsupdate.com. I tried whatever possibilities on the internet to troubleshoot but to no avail. I am now a serious windowsupdate troubleshooter. Below are 2 postings made by 2 gurus.

Extract 1 - MowGreen [MVP 2003-2006] from microsoft.public.windowsupdate newsgroup
Open Internet Options in the Control Panel. If you're NOT running a proxy server, click the Connections tab.

Click the LAN Settings button. If any boxes are checked there, UNcheck them. Click OK.

Click the Advanced tab. Scroll down to HTTP 1.1 settings. UNcheck the box next to " Use HTTP 1.1 through proxy connections ".
------------------------------------------------------------------------

Under Java ( or Microsoft VM ) which java package is installed ?
If the Java (Sun) JRE is installed make sure that the box next to it is checked. If the Microsoft VM is installed, make sure that the JIT compiler for virutal machine is enabled.
If BOTH are installed, uncheck the Microsoft VM boxes and make sure that the Java (Sun) " Use JRE .. " is checked. Click Apply, OK to make the setting stick.
-------------------------------------------------------------------------

IF that doesn't resolve the issue, try reregistering these files.
Go to Start, Run, type in

regsvr32 softpub.dll

Press Enter or click OK.
Do the same for :

Wintrust.dll, Initpki.dll, Dssenh.dll, Rsaenh.dll, Gpkcsp.dll, Sccbase.dll, Slbcsp.dll, Mssip32.dll, and Cryptdlg.dll

If that doesn't resolve the issue, download and install Windows Script 5.6 for XP/Win 2K :

---------------------------------------------------------------------------

Other possible causes could be Norton Internet Security, an entry in the HOSTS file that has a static IP address for Windows Update, or a security program ( popup and/or script blocker, or Bugmenot,etc. ) that is blocking access to downloading from WU.
