Problem rolling out ADO.Net Data Service application to IIS

Question

I am adding a ADO.Net Data Service lookup feature to an existing web page. Everything works great when running from visual studio, but when I roll it out to IIS, I get the following error:

Request Error
The server encountered an error processing the request. See server logs for more details.

I get this even when trying to display the default page, i.e.:

http://server/FFLookup.svc

I have 3.5 SP1 installed on the server.

What am I missing, and which "Server Logs" is it refering to? I can't find any further error messages.

There is nothing in the Event Viewer logs (System or Application), and nothing in the IIS logs other than the GET:

2008-09-10 15:20:19 10.7.131.71 GET /FFLookup.svc - 8082 - 10.7.131.86 Mozilla/5.0+(Windows;+U;+Windows+NT+5.1;+en-US)+AppleWebKit/525.13+(KHTML,+like+Gecko)+Chrome/0.2.149.29+Safari/525.13 401 2 2148074254

There is no stack trace returned. The only response I get is the "Request Error" as noted above.

Thanks

In order to verbosely display the errors resulting from your data service you can place the following tag above your dataservice definition:

[System.ServiceModel.ServiceBehavior(IncludeExceptionDetailInFaults = true)]  

This will then display the error in your browser window as well as a stack trace.

In addition to this dataservices throws all exceptions to the HandleException method so if you implement this method on your dataservice class you can put a break point on it and see the exception:

protected override void HandleException(HandleExceptionArgs e)
{
  try
  {
    e.UseVerboseErrors = true;
  }
  catch (Exception ex)
  {
    Console.WriteLine(ex.Message);
  }
}
