It appears you are using a proxy to download the URL database through a proxy.
Do you have Web Reproter to use Proxy settings to download the TrustedSource Database?
When you drill down to the IP address, is it the Web Reporter IP address?
It could also be that one proxy is using another proxy to download the database.
When I drill down, I do not get any information at all. Even if I pick "Detailed Web" I see nothing. And no, we do not download any Categorization in Web Reporter.
Could this be related to McAfee Site Advisor ?
