(Applies to: Epicenter Server)

Problem: You receive the following error message:

Cannot save scheduled task.  The error reported was “A specified login session does not exist.  It may already have been terminated.”

Solution:

This problem can be caused by Group Policy settings, particularly if you use the PCI compliancy standards for your domain.

You need to create an exception for Epicenter Server in the following Group Policy Setting:  

Network access: Do not allow storage of credentials or .NET Passports for network authentication

The path to the policy setting is Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Network access: Do not allow storage of credentials or .NET Passports for network authentication 

That setting needs to be Disabled.  If it is Enabled, it does not allow any stored credentials.
