Fixing the Secure Channel Windows 2012 — the trust relationship between workstation and domain fails?
May 5, 2014 in answer
You need to reset the machine account password for the computer in question.
First, make sure the ports listed here are open on your network between the server and the Domain Controllers.
Then, run this command from an elevated (Right-click > Run As Administrator) Command Prompt:
Netdom reset computer /domain:domainname /userd:domainadmin /passwordd:password
Where computer is the computer having trouble with its trust relationship. The username you use should be a domain admin.
Also, make sure that there aren’t issues with the SPN. See here for a reference on that.
