simple explanation.
a outside company wants to dial into my clients 2012 server and install some software.
we had a case where we did this before for a different client and they messed it all up.
so now we want them to have access to the server and install what they want, but things like exchange and AD and so forth we want them to have NO PERMISSION WHAT SO EVER.
it sounds possible but I don't think im looking in the right place. Any help?
