What to configure in the Remote Desktop Service after the introduction of a new domain controller?

Question

System administration

There are two Windows servers available - one Server1 (Windows Server 2008 R2) and the other Server2 (Windows Server 2012 Foundation).
The Server2 server appeared recently. Server1 has a remote desktop service, and all users connect to Server1 in order to work, for example, with 1C.
The other day there was a need to introduce a domain controller, because the number of workstations has increased dramatically. Selected Server2 for the domain controller role.
Tell me, please, what should be added / configured on Server1 after entering the domain controller? Do I need to configure something in Terminal Services on Server1?
Or is it enough just to enter Server1 into the domain and that's it?

Answer 1

1) Remote Desktop Licensing Server (you can raise it on the controller and assign it via GPO).
2) Will users remain local or will they be replaced by domain ones? In a domain, they can be combined into a group, and rights to resources can be given to a group, and not to specific users.
3) Firewall rules for domain networks on a domain computer will not apply to external networks.

Answer 2

It is enough to enter into the domain and in the terminal server settings specify the domain group that is allowed to remotely log in via RDP (at the moment you have the local group "Users. Remote Desktop." specified there).
Other policies to taste.
