The Login Is From An Untrusted Domain And Cannot Be Used With Windows Authentication Citrix
a day ago, I was doing small attempt to connect to my local SQL Server sspi handshake failed with error code 0x8009030c using IP 127.0.0.1. The IP is of my local machine and SQL Server is installed on the local box as the user is not associated with trusted sql 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 https://support.microsoft.com/en-us/kb/555332 Windows authentication. (Microsoft SQL Server, Error: 18452) The reason was indeed strange as I was trying to connect from 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 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/ 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 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 - SQL Server 2005 Samples and Sample Databases (February 2007) February 24, 2007Pinal Dave SQL SERVER - Detected a DTC/KTM in-doubt Transaction with UOW July 9, 2016Pinal Dave SQL SERVER - Error Fix: Msg 300, VIEW SERVER STATE October 12, 2015Pinal Dave 35 comments.
