I have 10 users & I am getting user group not individual user id's. Please help me.Reply Magne Rekdal January 17, 2014 12:32 pmPerhaps it was not a coincidence that these emails all came together.I have had an application run smoothly on 20+ sites for years, only to have this reported from two sites last week.The connection string was in both cases specified in an UDL file that the application refers to, and I used trusted login. The user's Windows account will (through an AD group) give access to both the file
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 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/ small attempt to connect to 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 http://blog.michelbarneveld.nl/michel/archive/2009/11/11/login-failed-microsoft-sql-server-error-18452.aspx 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 error 18452 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 and this was a bit strange to me. I started to think what did I change since server error 18452 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 - 2005 - Explanation of TRY…CATCH and ERROR Handling April 11, 2007Pinal Dave SQL SERVER - Fix: Error 2596 The repair statement was not processed.

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 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 i
