Issue

"An unexpected error has occurred. Your request cannot be processed at this time. If the problem persists, contact the web page administrator".
An error will appear in the System Event log in the Management Console: Could Not Authenticate

Product Line
Power Monitoring  Expert 9.x

Environment
PME side-by-side migration to 9.x

Cause
When clicking on Add subscriptions, Web Applications needs to authenticate IONUser (the Windows user that is created at the time of installation). In the case of system migration, a domain user from the old server could be authenticated and failed instead of the IONUser. No errors would appear in Event Viewer Application nor System. However, the following error pops up in Event Viewer Security.
