The Active Roles Web Interface shows the error "The system cannot find the file specified" when accessed using a load-balanced URL

If accessing the Active Roles Web Interface via a load-balanced URL, and if leaving the Active Roles session open for a long period, attempting to resume usage of the Active Roles Web Interface will fail with the error:
 
In addition, the logged-in user changes to NT AUTHORITY\SYSTEM

In order to resume usage of the Active Roles Web Interface, the user's browser must be closed/reopened or an Incognito browser session must be used.

In some instances, the user must also clean cookies in order for the Active Roles Web Interface to allow normal functionality.

Session management settings in IIS or in the load-balancing solution are not configured properly.

In the load-balancing solution, ensure that SSL Persistence (also known as "Sticky Sessions" or "Session Persistence" or something similar) is enabled on the Active Roles Web Interface URL.

The persistence setting should be for a long-enough duration to cover the desired use-case.

For assistance with configuring a load-balancing solution, please contact the vendor of that product.

In addition, in the IIS Manager under the Active Roles site, click on the Session State configuration and configure a duration that is long enough for the desired use-case, but which does not exceed the duration configured in the load-balancer solution.
