Active Roles provides a troubleshooting option, referred to as safe mode, that starts the Administration Service in a limited state. When safe mode is enabled, the Administration Service disregards all custom policies, workflows, scripts, scheduled tasks and other customizations that may block it from starting and operating normally, and rejects connections from any user other than Active Roles Admin. Active Roles Admin can connect to the Administration Service and make changes in order to fix or remove customizations that cause issues, and then disable safe mode.
How to start
Set-ARService -SafeModeEnabled $true
Set-ARService -SafeModeEnabled $false
