There are to line items as follows:
ASPNET-ISAPI-1.1-WebServiceHandlerFactory which points to C:\Windows\Microsoft.Net\Framework\v1.1.4322\aspnet_isapi.dll
and
WebServiceHandlerFactory-Integrated which points to System.Web.Services.Protocols.WebServiceHandlerFactory, System.Web.Services, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a
if change the application pool to be Classic vs. Integrated for this service I then receive the following error:
The page you are requesting cannot be served because of the ISAPI and CGI Restriction list settings on the Web server. When looking at the handler section it indicates this is "enabled" at the server and the web site level.
What else could be the missing?
