How to force Win server 2008r2 under the local administrator to come into the domain?

Question

Domain name market

The manual gave the task to install and configure the blockhost server on the server to deploy the blockhost on the station. The blockhost itself requires work under the local administrator and the function of logging into the domain by entering credentials is needed.
The bottom line is that on pure Win serv 2008r2 it does not allow you to enter the domain under the local administrator, the server is in the domain. Error "Login failed: username and password not recognized".

Answer 1

How do you plan to enter the domain under the local administrator, if there is no such user in the domain? Select this computer, not the domain, and go under locale.
