Just upgraded to 2012, from 2010/2011 BDIS.
I receive the following error message: "Your computer appears to be correctly configured, but the device or resource (DNS server) is not responding"
I have narrowed it down to the BD Firewall. I have troubleshooted everything else...router, network connection, flushed DNS, reset TCP/IP, tried a static IP, etc., and this does not occur on a different computer that does NOT have BD installed.
This error message only appears when I have BD Firewall enabled.
What's puzzling, is the upgrade process brought over all my previous settings, so there's not a setting I'm aware of that is any different than previously.
