Having an issue where it fails here with link to actual WCF:

I get the same result locally as in my godaddy .net 4.0 host. I’ve checked asp.net levels. IIS security at goddady is set to annonymous. If I enter the url to the Service in a browser I get some apparent issue with authentication which I’ve sent to Godaddy. If I do the same locally, I get what appears to healthy Web Service, though still get undefined from jsFiddle.

It’s all new to me .. so It’s been a mission.
Thanks.

Quote from the following article:

This all works fine when running it in Cassini, but when you want to
host it in IIS, you will need to take care two things. First, you will
need to ensure that IIS and WCF are correctly installed and
registered. If IIS does not seem to want to cough up your SVC files
(you can check that by trying http:////AjaxService.svc), try running the command ServiceModelReg.exe /i
/x from %WINDIR%\Microsoft.NET\Framework\v3.0\Windows Communication
Foundation. Restart IIS after running this command. Second, if you
created a default ASP.NET 2.0 website, you may run into this error
message:

IIS specified authentication schemes
'IntegratedWindowsAuthentication, Anonymous', but the binding only
supports specification of exactly one authentication scheme. Valid
authentication schemes are Digest, Negotiate, NTLM, Basic, or
Anonymous. Change the IIS settings so that only a single
authentication scheme is used.

To fix this, right-click the website in
your IIS manager and choose “properties”. Then click the “Directory”
tab, click the “Edit” button in the “Anonymous access and
authentication control” area. You will see that both Anonymous access
and Integrated Windows Authentication are selected. Unselect one of
them, then restart IIS. After that, the application should work
smoothly.

In your case replace Integrated Windows Authentication with Basic Authentication.
