I believe I’m correct … Please Help

I’m doing a rather nice project … thru a sorry temp agcy. But anyway there an issue that I believe can be solved. (In a network environment with roaming profiles. Its still possible to assign mandatory profile on a local machine for a particular user.) Am I correct? and if so could you give me the best way to handle approaching the client with factual info. to prove my point. It’s been years since dealing with profiles. But I believe I’m right.
