The trust relationship between this workstation and the primary domain failed

December 20th, 2014 Comments off


We power off some servers windows 2008 for more then one month and as we powerd on its started giving error while login in to the domain .”The trust relationship between this workstation and the primary domain failed ”

I got the articles and tested and used one which worked for me

Steps :-1 login local with administrator and password (.\Administrator)

Step :-2 run CMD with Run as Administrator

netdom.exe resetpwd /s:<server> /ud:<user> /pd:*

<server> = a domain controller in the joined domain

< user> = DOMAIN\User format with rights to change the computer password

For Example :- My Domain name :- Username gkhanadmin

>netdom.exe resetpwd / /ud:gkhan\gkhanadmin /pd:*

Step :-3 Reboot the machine

So I added this article for me to remmember for the next time .
