Norton DNS not protected message

Downloaded DNS client a little over a month ago.  In the last 2 weeks have been receiving "not protected" notifications with increasing frequency.  Log shows following messages 1) Unable to query the A record on Norton DNS server 198.153.194.1.  This operation returned because the timeout period expired.  2) Unable to query the Norton DNS servers.  There may be a connection problem or DNS queries may be hijacked.

Have remained connected with no indication of connection problem.

Upon resuming protection, log shows 1) Resetting DNS servers for Intel R ------- 10/100 Network Connection. 2) Previous servers were Norton DNS.

Am I looking at a significant problem?
