A good backup tool uses VSS Writers to achieve application consistent backups, which also truncates transaction log files. You can also achieve that without having to do a backup. Here are the few commands:

diskshadow

add volume D:

add volume E:

begin backup

create

end backup

If users are getting an authentication prompt when accessing domain resources through Always On VPN, make sure that Domain Controllers have the appropriate digital certificates. The certificate must have KDC Authentication, Smart Card Logon, Server Authentication and Client Authentication in the Enhanced Key Usage (EKU) field. The pre-existing Kerberos Authentication can be duplicated and used as a baseline template for the certificates.
