Problem: After rebooting a domain member Microsoft Server or Windows 7/8/10 PC, I receive an error, “The security database on the server does not have a computer account for this workstation trust relationship” when trying to logon.

Cause: This is usually caused by having a mixed Active Directory Server environment with legacy 2003 domains. The member Microsoft Server 2008/2012/2016/2019 servers and Microsoft Windows 7/8/10 PCs have mixed Active Directory domains.

Solution: How to Fix: The Security Database on the Server Does Not Have a Computer Account for This Workstation Trust Relationship:

• Unplug the network cables on the Server/PC that you are unable to log into.
• Login on to the Server/PC that is inaccessible with an account that has Administrator privileges.  This should be an account you have previously used to login with.
• Plug the Server/PC network cable back in while logged on.
• Change the domain name from FQDN (xyz123.local ) to the short name (xyz123).
  • Press Windows key + X and select System
  • Scroll to bottom and select, “Rename This PC (Advanced)
  • The System Properties screen will open, Click “Change”
  • A Reboot will be required after changing.
