Do I need a domain and ActiveDirectory?

Question

Computer networks

I will consult you, friends.
It is given: the elementary corporate grid, only about 20 users in three rooms in one building, the majority sits on wifi. There is Windows Server 2008 R2, on which 1C is running, users go there via RDP, including outside. The previous administration took the issue of security _a little_relaxed_, which is not right at all.
Now my task is to legalize all software, minimizing costs as much as possible (but without sacrificing security). And now I'm at a crossroads.
Option 1 - license all working computers on Win 10 Home for €135, land 1C on Linux, let them work in it via VNC, close admin accounts on working computers.
Option 2 - take Windows Server for €3500, license all users for Win 10 Pro for €279, put all users into ActiveDirectory, continue working as it was before.
In your opinion, does such a company need a second option?

Answer 1

I'm afraid now the economic aspect will prevail over the technical one.
Think about:
-What management tasks will AD solve for you?
- Isn't it worth it to put lightweight Linux on users' workplaces to completely reduce the cost of the project?
-Do you have the courage not to retrain staff for a different model of work?
- Will the staff have enough capacity to change the format of activities and the environment?
How are the budgets?

Answer 2

You need Microsoft Windows Server Essentials

Answer 3

RDP-shnyh users can be put on thin clients, the price of terminal feces is at least 2 times less than buying a full desktop axis.
if the server is good, then you can put almost everyone there ...
using a screw server + Ponix
and at the expense of 1c on Linux, then Centos6 + 1c8.3 + PostgreSQL is successfully spinning.
I think you can save a lot.
Microsoft Windows Server Essentials is good if the company is stable in development - there are restrictions on users and expansion, unlike the standard version, be careful!
