      Server Error in '/' Application: RE2

      By default, the installation of Discovery Center should work without any special configuration required within IIS. In customized environments where hardening settings have been applied, we have observed settings which inhibit the use of Discovery Center.

      We have included the error message along with the setting needed to correct the behavior.
