Login failed for user 'abc'. [CLIENT: 123.345.678.50] -- what ip is this?

  • I see this message int he error log.. The ip address mentioned is it the ipaddress of machine where someone tried using "abc: account or is it ip address of router or is it ipaddress of VPN connection?

  • It's the IP address of the machine that originated the connection to SQL.

  • If you want more info about the failed login itself, you can implement an event notification for failed logins.

    (see attachement)

    That provides interesting information.

    At instance level we have enabled "failed login reporting" for Login auditing.

    I only have the event notification active when I suspect hack attempts.
