Remote desktop at home connects but authentication?!?!?!

Ok I am about to setup a remote desktop connection so I can use my home pc at
work.

I have 3 computers at home.

So when I remote into the intended pc it does connect after I supply
username and password but it is asking local pc authentication a yes or no
question ...... how to disable that stupi dprompt so the connection can go
right in with out any local prompt otherwise this will never work.
