Answer 1

 

Are you sure, you are referring to a correct configuration file? Windows Service always refers to an app.config rather than web.config.

503 seem to be “System.ServiceModel.EndpointNotFoundException with No connection could be made because the target machine actively refused it stuff”.

From your configuration my suspect is below configuration should consists of a valid Address. (Just to verify these relative address is fine)

<endpoint address="Design_Time_Addresses/RackleyService.DataConnection/AcordConnection/">

<endpoint address="" behaviorConfiguration="CrossDomainBehavior"

Can you share the detailed exceptions and when you get this exception?

I'm sorry.  I meant my app.config file.  The problem is when I try to access

http://localhost:8731/Design_Time_Addresses/RackleyService.DataConnection/AcordConnection.  I get a

Service Unavailable

Anything 5XX range is server side generated which probably means when you deployed the server something was hosed in the configuration.  If it worked ok on your dev machine, then pay close attention to anything that sets up what IP Address or other communcations ports etc. will be used.
