Access is denied

[Meital Issers]

Hello,

I installed Mysql on NT workstation. The installation finished successfully. 
I launched the winmysqladmin.exe file and define a user for my DB.
When I tried to connect to this DB with the user I have just defined I got an error : 
" Access denied for user : 'usr@localhost' <using password : YES>

I did the same thing on other few workstation and it worked fine,

Thanks for help
