  1. It seems like the system is not able to query your DNS servers. Is it possible you have a traffic policy rule that is blocking (or not permitting) requests from the firewall? Normally there is a default traffic rule called “Firewall Traffic” that would allow traffic initiated by the firewall system.
    In the IP Tools screen you can generate DNS queries and ping requests to other hosts. Use this tool to confirm connectivity with those name servers.
    In the debug log you can right click and choose ‘messages’. There are two log events for DNS messages that will provide more details regarding these failed lookups. Make sure to disable the logging after you have captured enough log data. Based on the output here I guess it should only take a few seconds to capture enough details.
