Does anyone know a kind of software that allows controlling of other computer, but the server can configure permission control? For example, the server can define five users, one of them can control, but the other four of them can only view. Also, file transfer support is required.
I've tried TightVNC, it works fine with anything else, but it just does not support user permission control.
RAdmin can serve this job, but I wish to find some software which is free.
