Tuesday, February 06, 2007 8:58 PM Reply | Quote 0 Sign in to vote Can you please post the exact error message from the SQL Server errorlog including the number and state of the error? Also, to get additional information, please connect the SQL Server Profiler and monitor the Audit Login and Audit Login Failed events in the Security category. Check to see what are the credentials that appear for the login attempt. You'll probably not be able to login anyway if your credentials are different from the ones you specified in SQL Server, b

SERVER - FIX ERROR - Cannot connect to . Login failed. The login is from an untrusted domain and cannot be used with Windows authentication. (Microsoft SQL Server, Error: 18452) September 6, 2012Pinal DaveSQL, SQL Server, SQL Tips and Tricks35 commentsJust a day ago, I was doing small attempt to connect to my local SQL http://blog.sqlauthority.com/2012/09/06/sql-server-fix-error-cannot-connect-to-login-failed-the-login-is-from-an-untrusted-domain-and-cannot-be-used-with-windows-authentication-microsoft-sql-server-error-18452/ Server using IP 127.0.0.1. The IP is of my local machine and SQL Server is installed on the local box as well. However, whenever I try to connect to the server it gave me following strange error.Cannot connect to http://blog.michelbarneveld.nl/michel/archive/2009/11/11/login-failed-microsoft-sql-server-error-18452.aspx 127.0.0.1. Login failed. The login is from an untrusted domain and cannot be used with Windows authentication. (Microsoft SQL Server, Error: 18452) The reason was indeed strange as I was trying to connect from local box to local box sql server and it said my login was from an untrusted domain. As my system is not part of any domain, this was really confusing to me. Another thing was that I have been always able to connect always using 127.0.0.1 to SQL Server and this was a bit strange to me. I started to think what did I change since it last time I connected to SQL Server. Suddenly I remembered that I had modified my computer's host file for sql server error some other purpose.Solution:I opened my host file and immediately added entry like 127.0.0.1 localhost. Once I added it I was able to reconnect to SQL Server as usual. The location of the host file is C:\Windows\System32\drivers\etc. You will find file with the name hosts in it, make sure to open it with notepad.If you are part of a domain and your organization is using active directory, make sure that your account is added properly to active directory as well have proper security permissions to execute the task.Reference : Pinal Dave (http://blog.SQLAuthority.com) Tags: SQL Error Messages1722Related Articles SQL SERVER - Corrupted Backup File and Unsuccessful Restore October 24, 2010Pinal Dave SQL SERVER - Msg: 2593 : There are ROWCOUNT rows in PAGECOUNT pages for object ‘OBJECT'.

Leave new Anonymous September 6, 2012 8:48 pmI was laughing because you put in the loop back IP as your IP. Probably you should do a IPCONFIG and put in that IP as your IP.Reply lil_kid September 11, 2012 5:35 amYou can keep laughing but there is nothing wrong with using loopback IP (for localhost) in the host file.Reply Rohit September 11, 2012 5:52 amHi PinalI do not think doing an entry into hostfile is a solution. 127.0.0.1

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 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 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
