When attempting to log into Mgt Studio using windows authentication I am getting the error: Error 18452 (not associated with a https://support.microsoft.com/en-us/kb/555332 trusted sql server connection) . I added my domain\userName in sql with no problems and added the account to the sysadmin server role. However, I noticed my credentials on my pc are not listed as domain\userName but rather ComputerName\UserName. I think this is what is causing the problem but I am https://social.msdn.microsoft.com/Forums/sqlserver/en-US/48ee6a1b-9aad-48a6-90e4-b8f4b93d0107/error-18452-not-associated-with-a-trusted-sql-server-connection?forum=sqlsecurity not sure.

SQL Server 2000: Go to Start > Programs > Microsoft SQL Server > Enterprise Manager Right-click the Server name, select Properties > Security Under Authentication, select SQL Server and Windows The server must be stopped and re-started before this will take effect SQL Server 2005: Go to Start > Programs > Microsoft SQL Server 2005 > SQL Server Management Studio Right-click the Server name, select Properties > Security Under Server Authentication, select SQL Server and Windows Authentication Mode The server must be stopped and re-started before this will take effect..." http://www-1.ibm.com/support/docview.wss?uid=swg21119906 It has solved my probl

First installed Windows 2008 R2, then added and configured the DNS and Active Directoryroles. Installed Sql Server 2008 R2. Started the install of SharePoint 2010. Untill this point everything went error 18452 very smooth.But during the installation you have to give the database name where the SharePoint databases will be created. And since I didn't like the hostname,I wanteda dns entry for it with a better name. Should be simple, right? Started the dns server management consoleand added the entry sql.mb.local pointing to my fixed ip.Used the new name in the SharePoint installation screen and got login failures. Hmm, what is going on sql server error here? Is Sql service running? Did I used the wrong ip? Those all checked out fine. So I started the SQL Server Management Studio. I could connect using the hostname and ip addresses but not through the dns name. If I did that I got a nice little box saying: "Login Failed. The login is from an untrusted domain and cannot be used with Windows authentication. (Microsoft SQL Server, Error: 18452)" Searched for the errors on internet and found some blog postings about enabling Mixed Mode authentication, instead of Windows only authentication. But I was sure it must also work with just Windows authentication. Next step was to look in the eventviewer and there was an event 17806in the Application Log saying "SSPI handshake failed with error code 0x8009030c while establishing a connection with integrated security; the connection has been closed." and in the Security Log there was an event 4625 saying "An Error occured during Logon". I also tried it with a CNAME record as alias for the host name and that worked perfectly. I also checked if there were SPN's registered to the sql service account. None were registered. Also checked for MSSQLSvc spn in the domain, also none found. But by this time I was convinced it

All machines are in the same domain. All user accounts in use are domain accounts. SQL runs one instance of each SQL Server 2005, 2008, 2008R2, 2012 and 2014. Since tonight (DC rebooted to install automatic Windows security updates), accessing the SQL 2005, 2008 and 2008R2 instances through Windows authentication does not work properly anymore: When accessing one of these instances from one of the clients using Windows authentication the following error occurs (it's the 2008R2 message, the 2005/2008 messages are similar): Login failed. The login is from an untrusted domain and cannot be used with Windows authentication. (Microsoft SQL Server, Error: 18452) Obviously, the message text does not apply, since there is only one domain. Now the surprising thing is: As soon as user is logged in on SQL (starting an RDP sesson or even simply running runas /user:MYDOMAIN\someuser cmd and keeping the window open), this user can access all SQL Server instances from all clients without any problems until the process running with that user's credentials is closed. This means that I can just workaround this problem by executing the above runas command for all users on SQL once (and keeping the windows open), but, obviously, something is severely broken. I suspect tonight's security updates on DC have something to do with it (since that's the only thing that changed), but I'd rather avoid uninstalling and rebo
