Cannot download file from email and/or windows update

Hi all,

I have 2 home PC run both running XP Pro with SP1.
Both PCs can go on-line via router without any problem.
Yesterday, one of my PC took hours but could download files from my email attachment (a very small file of 4K).

I have updated the latest patches with windows update.
I ran norton system works & Adware 6.0 (latest virus definitions & reference files),
there are no virus or spywares found.

I have shutdowned Zone Alarm version 4.5 with the same result.

I have tried every possible means that I known to fix the problem without success:

1. Clear internet cache, cookies and history
2. Reset internet security to medium (default)
3. Change the Lan settings by uncheck the Boxes "Auto detect setting" & "Use auto config script"
4. Check the services to ensure all necessary services are started/restarted
5. Re-installed IE. After re-installed IE, I went to windows update site to download the patches. There are 4 critical updates and the download file window opened but it never start downloading. I have changed the catroot2 file to catroot2 old but it still couldn't download. I have also restarted the cryptographic services.
6. I have changed the RJ45 cable (cat 5E).
7. I have tried to direct connect to my ADSL modem

Can any expert help me to solve this problem oththan just re-install XP Pro?

TIA
