My friend has a small business, he has a few employees already.
What he is looking for is to have a solution to manage information/doc/email and access controls.
My first thought is to get a windows server 2012 r2 working as a domain controller, set up user group, users. The next stage is to set up a windows file server to be joined into the domain, set up file access permission for various users ...
Can anyone here please share some suggestion/video/references so I can simply follow instructions step-by-step?
