Detail:  A default zone url is pointing to the machine name of a web front end.  Since this installation has more than one web front end, this can result in a variety of errors including incorrect links and failed operations.

Solution:  A unique domain name will be created for the web application and once the Public Url is set to this domain name, the error will clear.  The error exists because there are multiple mapped access points (by server name) instead of a single url.
