    Well, the message shows your client application is at least connecting to a running server

    Some possible causes:

    a) trying to connect to the wrong server (where login and/or password is different or doesn't exist) Check your $DSQUERY setting or -S parameter.

    b) wrong login name

    c) wrong password

    d) account is locked (possibly due to too many failed login attempts, for instance)

    Dear Bret,

    Thanks for your valuable answer.

    The error reason with customer system was c) wrong password
