The Data service is unavailable

Article # 3042125 - Page views: 41


When attempting to launch any Insight application, the error "The Data service is unavailable"  appears.



When enabling Windows authentication on your IIS server(s) to support Insight using Windows authentication scheme, it is required to leave Anonymous access for the data service ("WcfDataService") application enabled - simply enable Windows authentication in addition to that.

Also make sure the correct account is used in the application pool.

This requirement exists for all supported versions of Insight.
