How to remove the domain registration at the entrance?

Question

Windows Server

1. There is windows server 2008 R2
2. There is windows 7
Connection goes through active directory. There is a shs domain (created in windows server 2008 R2), we create a user for a computer under windows 7 and when you log in to a computer under windows 7 under the teacher user, he assigns the "shs \" domain to it. Here's how to remove the addition of this domain so that the user is still under the domain?
It looks like this:
shs\teacher
Enter the password
Here you need to remove this shs so that only the teacher remains, but the user is in the domain

Answer 1

Not possible by design
However, you can pervert and write an authorization package msgina but this solution is so-so
I wrote such a thing for logging in via rfid if I want to throw it off

Answer 2

You can do it on the local user's computer, log in under the name .\local_user. But all the services used will still ask for a domain user, and it will have to be specified, so there is no getting away from this.
PS And it seems that Windows removes the domain name from the username, writes the current domain below ... Just write the name, and go!
