In environments where security is a concern customers might decrease the session expiry time to reduce the risk of an unattended computer providing access to confidential information. When the session expires, subsequent requests are made as an authenticated public user. The user can't sign in to the device until the next scheduled access time commences.In the application settings ( Admin → Settings) the Session duration (minutes) can be adjusted. When a user's sign-in time expires, SMB sessions terminate. This policy setting doesn't apply to administrator accounts. CountermeasureĮnable the Network security: Force logoff when logon hours expire setting. If you disable this policy setting, users can remain connected to the computer outside of their allotted sign-in hours.

However, local account policies for member devices can be different from the domain account policy by defining an account policy for the organizational unit that contains the member devices. By default, workstations and servers that are joined to a domain (for example, member devices) also receive the same account policy for their local accounts. A domain controller always pulls the account policy from the Default Domain Policy Group Policy Object (GPO), even if there's a different account policy that is applied to the organizational unit that contains the domain controller. The account policy must be defined in the Default Domain Policy, and it's enforced by the domain controllers that make up the domain. For domain accounts, there can be only one account policy. This policy setting doesn't apply to administrator accounts, but it behaves as an account policy. This setting affects the Server Message Block (SMB) component.
