Hi,

I seem to be having some trouble viewing most advertisments; Mainly and most inportantly Google Adsense.
Ever since I upgraded from Windows 98 SE to Windows XP Pro I've been having this problem.

This problem is happenning in both Internet Explorer and Firefox, and it's not my ISP or router since it works on my dad's computer.

I've ran all my anti-virus and anti-spyware programs several times since this problem appeared and I've tried it with a direct connection to the ISP without my router and without my firewall.

Some other ads don't work either. For example, the ads on slashdot.

This has been happenning for a while, but it's only recently that my site has become more popular and I've decided to put Google ads on it, but since I can't see them, I'd rather wait until I can to put them on. :P

If you could please help me it would be greatly appriciated.

I have the same problem. I can not view AdSense and some websites on my PC usiing win2000. It's not my firewall or my anti-virus software. I use Linux most fo the time and the ads are viewable then. I'm embarassed because I'm a Network Tech and have not been able to correct my problem. HELP !!!

I'm having this problem too.

Has anyone tried looking at their hosts file?

Look for a file named hosts in your windows directory. Probably down in SYSTEM32\DRIVERS\ETC\

If you have any entries besides
127.0.0.1 localhost
then you might want to figure out who put them there.

As explained here (http://www.mvps.org/winhelp2002/hosts.htm), the hosts file can be used to block domains.

The only possibility I can think of is that somewhere on your computer, you have an AdBlocker installed. If you have an internet security program such as Norton Internet Security, or a popup blocker such as the one made by Google or Yahoo then most likely there is something blocking ads.

Also, try looking at the source code of your site by launching it in Internet Explorer. Right click --> View Source.

Now, I have Norton Internet Security's ad blocking software and I see the following near the top of the source code. If you see anything similar to the following then there is probably ad blocking software activated:

<script language="JavaScript">
<!--

function SymError()
{
return true;
}

window.onerror = SymError;

var SymRealWinOpen = window.open;

function SymWinOpen(url, name, attributes)
{
return (new Object());
}

window.open = SymWinOpen;

//-->
</script>


-----and that is pretty much all I can think of. Hope that helps.

Well, nothing worked. Thanks anyways.
I sent google an email and they replied to me by telling me to make sure some internet options were enabled, but they already were.

I'll probably get an email later today or early tomorrow.
As for now, the problem still remains.

EDIT: Problem solved. For some weird reason I had two hosts files.. one small (the one I was looking at), on huge. I'm now using the one from my dad's pc. :P
Thanks for telling me to check my hosts file!!
