Subject: When will clients/applications do a smb2 session reauth

Hi,

with SMB 2.1 (and higher) it's possible to do a session re-authentication without getting a STATUS_NETWORK_SESSION_EXPIRED. With SMB 2.0 STATUS_REQUEST_NOT_ACCEPTED is returned.

In what situations do clients do a (pro active) reauthentication without getting STATUS_NETWORK_SESSION_EXPIRED from the server?

"3.2.4.2.3.1 Application Requests Reauthenticating a User"
is the related section in [MS-SMB2].

What layers in the client use this feature?
How can I trigger this?

Is the reauthentication only used with the same user account or also to switch a session to a different user (which is possible)?

BTW: is there a reason why <dochelp at winse.microsoft.com> doesn't work anymore?
