Issue

When attempting an export during the CTS process, the remote server returned an error: (401) Unauthorized.

Resolution

This error occurs when attempting to CTS on sites that use Integrated Authentication, also called Windows Authentication.  

To resolve, enable Anonymous Authentication for the CTS.aspx file in the production Cransoft's IIS site. Disable all other authentication methods for that one file.
