Network security: Force logoff when logon hours expire This policy setting, which determines whether to disconnect users who are connected to the local computer outside their user account?s valid logon hours, affects the SMB component. If you enable this policy setting, client sessions with the SMB server will be disconnected when the client?s logon hours expire. If you disable this policy setting, established client sessions will be maintained after the client?s logon hours expire.
