Fiddled with Windows Server 2008 r2 user profiles... is this reversible?

Question

System administration

I decided to delete the profiles of several server users in the PU, namely in "Setting additional user profile properties", where the profile type and size are indicated. I deleted the profiles of three users, and when one of them was deleted, a warning window popped up, I don’t literally remember something like: “deletion is impossible”, but by clicking “ok” the profile disappeared from the list.
I rebooted the server, I went into Remote Utilities (I poked around remotely through it), and there was a black screen and nothing more ... The remote task manager only shows in processes:
smss.exe
System
System Idle Process
Services are running, there are no active users in the system, including administrator number. Empty. It is there but not included.
The question is that physically I will be at the server tomorrow evening, but now what should I do? What did I screw up???
PS. I can't even reboot the server remotely... it doesn't respond.

Answer 1

It seems that the user about whom the warning popped up was the Administrator (or Administrator, if the English version). And you successfully smashed his profile :) I don't know how, usually Windows doesn't allow you to shoot the user's profile under which you work.
Now only to the console and from it to go.

Answer 2

You crashed the administrator's profile. If it was a domain administrator, then you need to go local. Otherwise restore from backup
