Solve the problem that "the security database on the server does not have a computer account with this workstation trust relationship"

When 2003AD was migrated to 08AD, when 08AD snatched the host role and restarted it, when the domain administrator logged on, the system prompts "the security database on the server does not have a computer account trusted by this workstation "!!

I thought about the reason. Because it was a short time, I changed the name of the target host to the name of the source host without waiting for the source host to be renamed. It is equivalent to the problem caused by entering the domain with the same name.

Solution: log on to the target host as a local administrator and click computer properties to remove the suffix of the primary DNS of the computer. After the restart, the Domain Administrator logs on successfully.

Let's talk about how to forget the server password. The system is windows server 2008R2. For details, see the BLOG of yangguan endeavor.
