How are you copying the profile? The way I do it is to set up a share on the server, log in to the machine that I set up the profile on (as administrator), go to the System dialogue (right click my computer -> properties one I mean). On the advanced tab, click Settings under 'User Profiles', select the relevant profile and click copy to, choosing the share path. Then change the usual .dat file to a .man file and there we go.
3. & How come that when i setup a profile for Students, the username i took the profile from has access to a piece of software but when i try to apply it to another student they get a permissons error..?
