Kurt,

Just want to thank you for the reply and help.  You very last question pointed me in the right place.  Unknown to me, a secondary DNS server was down (crashed).  As soon as we brought it back up, the problem vanished.  Thank you very much.  In the future (hopefully I won't need to), I will be more specific in the problem description.  Once again, thank you!
