 <p>Ok, so assuming that my corporate domain name is bar.com, everything seems to route fine as long as all host entries that reference "bar" always followed it with ".com" </p> <p>If I tried to enter <code>foo.bar.net</code> or <code>foo.bar.org</code> or <code>foo.bar.floop</code> as my host, I get "No Response from DNS Server" errors. If I enter <code>foo.bar.com</code> the host resolves. </p> <p>While I received these errors as "Vital Security Proxy Errors", a developer on my team that is helping me test this received Trustwave errors instead. </p> <p>This seems to be something specific to our network security policies.</p>
