How to remove a number from an AD domain?

Question

Active Directory

Good day to all!

The company decided to move servers from one subnet to another. To do this, they even allocated a server on which they deployed ESXI in order to create virtual servers for the move.

For migration, I chose Starwind V2V Converter software. Everything was fine, but when I turned on the virtual machine, I forgot to turn off network access... as a result, now the main server and the server on ESXI have a domain name that looks like this: "DOMEN.RU 2", but it should be without a deuce.

Where did this duo come from? How to remove it? What are the causes and consequences of this incident?
Why do machines on different subnets that are closed to each other (subnets) see each other?

This did not affect the operation of the main server in any way, because users sit on it as before. Yes, and on the virtual, too, it does not interfere with work, it just hurts my eyes + I can’t figure out this phenomenon.

I read about SID on the Internet, but I didn’t understand if it suits me.
