In my office we have 6 computers which are connected by a Hub. I have created a user group call "CECILIYAN". I have connected internet one port of that hub. So any one can access to Internet in that group. Now I want to make my PC as the Administrator of this user group. And I should be able to control other PCs by blocking USB Pen drives & Internet Access & other things. Please let me know how to do it. Is there any third party tool or registry editing or any way to control that things Thank you.
