Mandatory profile for terminal server

I would like to assign a mandatory profile for my terminal users. I would like all of of my users connect the terminal server will use a same profile because I don’t several hundred profiles store on my terminal server. My users already have roaming profile setup in their profile. I create a mandatory profile and shared it out and assign this patth to my user under Terminal service profile path. However, when my user log in, they see this message “Windows cannon locate your roaming profile and is attempting to log you on with your local profile…” What did I do wrong? any suggestion how to handle this problem? Thanks
