Error when using Web Interface Sites Configuration Wizard or the Active Roles Configuration Center:
Failure (Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index)
This error is caused if there are no HTTP bindings in IIS.
If there is a reason, such as security requireements, to not have any HTTP bindings in IIS, then this error can be safely ignored and considered a warning.
Otherwise, create an HTTP binding in IIS.
