The trust relationship between this workstation and the primary domain failed.

Question

We have a database server that is constantly falling off the domain. I've rejoined it to the domain several times, but after a little while, the trust relationship fails again. I've seen several articles like the one below. But, they all seem to be about just rejoining the domain without actually discovering and fixing the cause. How should I go about troubleshooting this?

Answer 1

There are multiple events referring to different domain controllers in the server system log. Here's an example:

Log Name: System
Source: NETLOGON
Date: 11/17/2021 12:03:16 PM
Event ID: 3210
Task Category: None
Level: Error
Keywords: Classic
User: N/A
Computer: dbserver.our.domain
Description:
This computer could not authenticate with \dc.our.domain, a Windows domain controller for domain DOM,
and therefore this computer might deny logon requests. This inability to authenticate might be caused by another
computer on the same network using the same name or the password for this computer account is not recognized. If
this message appears again, contact your system administrator.

Answer 2

1. Please try to disable any Antivirus or firewall you may have.
2. Please try to add this server to same VLAN or ip subnet.
3. Please check preferred DNS ip and it should be of AD DC.
4. Please try to rename this server if its possible and rejoin to domain.
5. Please check AD Replication health is good in your environment.
6. Please check if date and time are sync with AD and not screwed.
7. Please try to assign different ip for this server.
