published asp.net web app and published wcf service not connectiing in IIS

Question

I have published both my WCF service and ASP.NET Web application in IIS but i seem to have a problem connecting to the database after publishing. Its like the two cannot see each other. I have tested both and saw that they have been successfully published.

the service reference is referenced in the web application and works as normal when i run the web application locally but not working after publishing.

Is there a setting that i am missing. Both are hosted on IIS.

Answer 1

There is possibility that you are using Windows authentication, I mean if Integrated Security = true in your connection string than make sure your Windows authentication enabled in your IIS.

Do this if this is the case. IIS7: Setup Integrated Windows Authentication like in IIS6

if this is not the case than this answer is helpful for you Change connection string from development to production when publishing
