Activex problem

When I open IE6 with Yahoo and try to display "In the news" section, I get and error "present configuration prevents execution of ActiveX" I clik OK and the page is displayed OK.
Also when I try to enter to "windows Update" I get the error "0X800A1391 "
When I look in the "MS Knowledge base" it says "the problem is caused due unable to download the ActiveX from Windows update site" and recomends to enter the addresses of MS Update Sites into IE Tools > security >Trusted sites. Internet Security zone is medium.
I performed that procedure without results.
Any assistance or comments will be greatly appreciated.
I Scaned the PC with ZoneAlarm, Ad-Aware and Spybot and it appears to be clean.
Win2K Pro sp4, pIII 863, ram 384, IE6
I made a quick test changing Internet Security from medium to low, also without results.
Finally I found the problem, ZoneAlarm was configured to block Java, ActiveX,
now everything woks OK.

 

Thanks for posting back with the update and your fix.
