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 not sure. Can anyone lend a hand? I'd appreciate any sqlserver error 18452 help, Thanks.

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 problem, so I hope it could be helpful for you too.

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 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/ my local SQL 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 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 error 18452 local box to local box 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 server error 18452 I had modified my computer's host file for 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 - ERROR: Autogrow of file ‘MyDB_log' in database ‘MyDB' was cancelled by user or timed out after 30121 milliseconds September 14, 2015Pinal Dave SQL SERVER - SQL Server 2005 Samples and Sample Databases (February 2007) February 24, 2007Pinal Dave SQL SERVER - What is New in SQL Server Agent for Microsoft SQL Server 2005 February 26, 2007Pinal Dave 35 comments. 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 5:5
