I am getting a Windows Server Backup error which reads...
"A specified logon session does not exist. It may already have been terminated" Whenever I try to save a backup schedule.
In trying to diagnose this problem I've located this Microsoft post which says to "disable" the "Do Not allow storage of credentials or .NET Passports..." GPO as a solution to the problem. https://support.microsoft.com/en-us/help/968264/error-message-when-you-try-to-map-to-a-network-drive-of-a-dfs-share-by
I want to leave this GPO the way it is because cached passwords are a security liability that I cannot accept.
Is there an actual way to make Windows Server Backup function in a secure manner with this GPO setting enabled? I usually work around the problem in Task Scheduler by setting the task to run as SYSTEM, but this doesn't seem to work with Windows Server Backup.
