Extract the sql table with windows terminal cmd

Hello all,

We use ProjeQtOr since 1 year and we have no problem with it.
Today i want to extract the projeqtor table with terminal cmd.
I try to find a similar problem but i dont find it.
I know we can do it with putty but i don't understand why the cmd terminal don't want to connect ( as you can see on picture )
i had all rigth for this account so there is no problem with it normally.
Maybe i forget a command ?
If you can help me with that it will be a good support.
Thanks in advance and sorry for my English !
