Error Message

No error is shown to the user, but the Windows System Event Log on the EV server hosting the Dashboard website will show events:

Log Name:      System
Source:        Microsoft-Windows-WAS
Event ID:      5021
Level:         Warning
Description:
The identity of application pool DashboardAPI is invalid. The user name or password that is specified for the identity may be incorrect, or the user may not have batch logon rights. If the identity is not corrected, the application pool will be disabled when the application pool receives its first request.  If batch logon rights are causing the problem, the identity in the IIS configuration store must be changed after rights have been granted before Windows Process Activation Service (WAS) can retry the logon. If the identity remains invalid after the first request for the application pool is processed, the application pool will be disabled. The data field contains the error number.
