How do you allow non-adminstrators the ability to edit com ports?

Question

I am trying to allow non-administrators on a domain to be able to edit the com ports because when a non administrator tries to do it the port just reverts back to its default in Windows 7. If this can be done via script through group policy that would be amazing but a solution would be awesome too. As in I only want them to have the permission necessary to edit the ports and nothing else. Nor do I want to give them admin rights in the group policy or give local admin rights because that would be security issue.

Answer 1

if you want to allow access to hardware, generally you are going to need to give some admin rights.



If this is about using com ports for printers, or com ports for Palm pilots.. or some specific use.. then perhaps there is software already out there,

perhaps you could create a hardware profile for the user

.. perhaps you could create a piped device, then give the users access to the pipe you created.



The specific needs - more description might help the more knowledgeable WinAdmins to help.



[EDIT - in response to added detail]

I'm a bit confused, but I'll try.. if you are working in a lab where the users/students have access to open motherboards, then you can work with hardware hacks, jumpers, and tweaking the drivers. The manufacturer of the mobo or parts may even have a devkit (developers kit) that allows you to directly program the device.

However, since you say you are using Win 7 and group policy, I think you are using full workstations. Win 7 ( and most of the more modern OSs) really go out of the way to prevent direct hardware access. If you give your users hardware-level access, then they can defeat nearly any software protections in place. ( with the knowledge and or tools)



There are also external port adapters, dongles, and other devices ( think like the old game cheat adapters - you put that inline with a controller, and moved a number of switches to change the way a game reacted)... that you can put in.



If you want to teach about port behaviours, I'd get some older DOS or Win 98 or workstations, use Linux (without SELinux) or get an Arduino kit for your users.

if you need something more.. restart the question with more specific info, please.

properly carried out, Puddleduck for protecting off the fags!!! it is totally stressful or maybe after years I nevertheless experience that i might like to eliminate darkness from. And if the next day they introduced that cigs have been ok to smoke then i might commence lower back immediately...yet i don't comprehend no count number if the tax from the sale of cigarettes can help keep the NHS ticking. If that became into the case then why might the government spend a great number of money to inspire human beings who smoke to supply up? might they actually need to unfastened that kind of gross revenues for reliable? i've got heard that the money they create jointly from the taxes on ciggies pass to anti-smoking campaigns and none of that money pass to the NHS or to handle human beings who smoke. There are additionally anti-smoking charities and that i'm confident they get a extensive bite of this money. Nicorette products may be gained unfastened from the NHS besides. So why might they pass into this great expenditure in ordinary terms to shoot themselves interior the foot by employing loosing a great sort of taxes from human beings who smoke?

I think you have answered your own question regarding security issues. It can be done, but it would then open the doors to misuse of computer systems. Some things are best left alone.
