The computer entering AD is physically moved to other office, without AD. How to login?

Question

Active Directory

When you try to log in as a domain user, windows 10 taken to another office (in this office is a regular peer-to-peer network without AD) swears that a server that can service the request has not been found.
Between the subnets where AD and this Windows is, there is a vpn, that is, I can apply on LAN. (there is, of course, an option to raise the l2 tunnel by setting the same subnets, but not comme il faut).
From the local administrator of a computer the password is lost. I can boot from the Windows installation disk, break the local account, but maybe there is a more correct way? There are accesses to routers and to the AD controller.

Answer 1

Well, if you can apply locally, and ping the server back from the server.
Write the address of the domain controller manually in dns, or on the router if it allows, or on the computer in the hosts on the edge.
And the first dns nameserver in dhcp substitute the address of your hell.
Most likely it will work.
Raise the tunnel between networks will not work.

Answer 2

Unplug the network cable

Answer 3

The easiest is to disconnect the network cable, login to the system and connect the ethernet back. Did the computer move permanently or temporarily?

Answer 4

Change Local Account Password Using Microsoft DART

Answer 5

reset the password of the local administrator - images in the internet
computer transferred to the office of another company if not - just specify (and ensure the operation) of the DNS controller.
