Hi, We have around 8000 users in one Domain and I am getting this error only on one system again and again. Trust Relationship Between Workstation and Domain Fails CLIENT SIDE What i use to do is remove the system from Domain and Add again. Once I get the login, after that when I restart, the same issue again. For temporary basis, what I do is remove the lan chord, go into the system with Cache Mode login of user and then reconnect cable to serve the purpose. SERVER SIDE I have removed and deleted the profile from the Active Directory that was created, still facing the same issue. Please provide a complete resolution and also prevention of this issue if possible. Thank You !!

This article may help: http://www.petenetlive.com/KB/Article/0000504.htm Regards Milos

Thanks Milos but i have already done that. If you might have read "SERVER SIDE I have removed and deleted the profile from the Active Directory that was created, still facing the same issue. Please provide a complete resolution and also prevention of this issue if possible. Thank You !!" However i have not tried to Reset the account. Will do that however like the article says it doesnt usually help. Any other alternatives ??Regards, Pratik Mehta

Hi, I fully understand that you have tried to rejoin the domain, but we may still need to rejoin the domain one more time. You can join the domain from the client if at the same time you can provide an administrator username and password on the domain. Or You can delete the existing computer account in Server Manager, recreate the computer account, synchronize the domain, and then on the client rejoin the domain. If the issue persists, let us use Netdom.exe command to reset the member security channel. netdom reset 'machinename' /domain:'domainname For more information, please refer to this. http://support.microsoft.com/kb/216393Kim Zhou TechNet Community Support

You mean shall I rename the Computer and then ask him to join the Domain again ? I have done the first 2 steps you mentioned however please let me know what is the netdom reset command. Should I use it on Client or Server and where exactly on the AD-DNS server or where?Regards, Pratik Mehta

Hi, Netdom is a command-line tool that is built into Windows Server 2008 and Windows Server 2008 R2. It is available if you have the Active Directory Domain Services (AD DS) server role installed. It is also available if you install the Active Directory Domain Services Tools that are part of the Remote Server Administration Tools (RSAT). For more information, please refer to this. http://technet.microsoft.com/en-us/library/cc772217(v=ws.10).aspxKim Zhou TechNet Community Support

I would suggest to check the computer time against DC. There is a possibility that the computer time is off for more than 5 min which would create trust problems as well. Monitor the computer for a bit without being connected to the network and see if it starts loosing the time. http://www.implbits.com/About/Blog/tabid/78/post/don-t-rejoin-to-fix-the-trust-relationship-between-this-workstation-and-the-primary-domain-failed/Default.aspx Just change your computer password using netdom.exe! 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

I havent performed these but came to know that there were two systems with the same Host Name. I want to know that even if on purpose how that was possible that two hostnames of the computers were same in one domain, one forest.Regards, Pratik Mehta
