WCF Rest kit is showing my internal server names in the /help page

I have a simple WCF Rest service using the latest MS Restful preview kit. Everything works fine, site works as expected. However when I go to my /help page as in http://services.acme.com/help what is being shown is --

UriTemplate                 http://serv17.acme.com/Service.svc/Ping/string={ping}

Method        开发者_JS百科                  GET

Response Format      Xml

Response Schema    http://serv17.acme.com/Service.svc/help/Ping/response/schema

Response Example   http://serv17.acne.com/Service.svc/help/Ping/response/example

Why is the help showing my internal server name, http://serv17.acme.com/ instead of http://www.acme.com/?
