SSPI handshake

  • Why do we see this SSPI handshake failed with error code? Is this something to concern about?

  • I've seen messages like this in connection with password expiration. I think it occurs when someone attempts to connect with a Windows login whose password has expired. Would this be the only reason?

  • There could be many reasons:

    a) Password expires (check account policies or take help from network team)

    b) AD Server offline to authenticate the user.

    c) Unable to generate Kerberos ticket ... with Domain controller.... could be a registry issue.

    d) Other network issues.

    Use a different user or SQL authentication and check the error logs.

    =======================================================================

  • Hi,

    we got this error sometimes, and we don't care about it.

    I think, the error occours, if the AD controller, the sql server is connect, is in maintenance, and the next AD controller is used. Maybe this will need some seconds.

    Kind regards,

    Andreas
