Have a client running a single 2008 SBS server on a network protected by a Watchguard firewall and Trend Worry Free Business.
A client has reported that they cannot access a particular .co.uk url that quite innocently has the word child in itl. When anyone on the internal network regardless of browser choice (including on the server itself) goes to that URL you just get a white screen. IF they take same PC out of the network the URL works fine.
I've gone into the Watchguard config and added the IP address of the website to the whitelist (you can't add url's) and confirmed that WebBlocker is actually switched off.
I've also gone into Trend and added the URL to the allowed list under Web Blocking and Web Behaviour but nothing seems to work.
Was wondering if there might be something on the 2008 SBS server itself blocking the URL?
Any suggestions gratefully received.
