I'm a newbie on Novel thus I need your help o mighty gurus....

I have just created a new user on consoleone. Now that thing is if i try to login from the server using the account that I have created, I don't have any problem. But if I try it on the user's computer, after I login there is this 2nd screen that pops up asking me for the windows password...

what could be missing on my setup?

please advise

thank you very much
