I am having this issue here. My server cannot go into the internet and and mails cannot send out to external email. However, external email can come into my server.
I launch internet explorer and this is what i receive (see attached). I did a full system scan using superantispyware and symantec endpoint v 11. Nothing found. Reset my IE settings but to no avail.
I cannot ping to any external site. eg Google, yahoo etc2
machine: windows server 2008 OS
Application running: Exchange 2010
