Tell me, is it possible to combine the roles of AD, Files Server, IIS?

Question

System administration

There is only one physical server, the server 2016 license is also one

Answer 1

Can. But you don't need it :) Especially if there is a high-traffic file cleaning service and there is a proxy with authentication through the domain. Especially if IIS, which is so loved by "hackers". As far as I remember the terms of the license, three virtual machines can be raised there. Put the role of Hyper-V and raise AD separately, separately with IIS, at least.
