adsense ads disappearing in office pc

[waiman39hk]

My boss made some changes to the DNS settings yesterday and now the adsense ads disappeared in the office pc.
They are showing normally when I view the adsense page outside the intranet.

What would be affecting this?

Check your "hosts" file (if you are on windows). It is possible to disable google ads from there by adding just one line.

What do you add, joelgreen?

The file is:
<WINDOWS>\system32\drivers\etc\hosts

...but I can think of nothing that will disable Google ads.

AdSense is easily blocked by adding one line to the hosts file (by blocking pagead2.googlesyndication.com).

But it sounds kind of like the filter was added at the firewall level, in which case you'll have to get access to that in order to remove the filter.

Google ads will not be shown on the computer if "hosts" file contains following line
127.0.0.1 pagead2.googlesyndication.com

Some publishers add that line on their computers to avoid clicks on own ads :)

Humph! I've been trying to think of the downside, but cannot see one.

Thanks, joelgreen.
