Here is our setup: We have four SQL servers that are in replication with each other. We add a new user to Windows Active Directory and add them to a group that is in SQL Server that we have been using for ages. The new user, when trying to authenticate using Windows authenication returns that error in the subject line. But, any users that were http://stackoverflow.com/questions/11058803/sql-server-2008-error-18452-the-login-is-from-an-untrusted-domain-and-cannot-be previously in Active directory work fine. At one point I had gotten SQL Server "caught up" becauuse we had a group of users that could not log in because of this error. I did some changes to the SPNs and ended up making it so no one could log in. Then I realized how the SPNs were supposed to look and fixed it. Then I guess some magic happened and those users were able to authenticate. I thought it was fixed, but it is obviously not as we had to add one new user and they cannot authenticate. What is interesting is that the user can authenticate with three out of the four SQL Servers. It is only this one server that is working incorrectly. I set up two SPNs for the SQl Service on this sql server. They look like - MSSQLSvc/[servername].[domain].local:1433 MSSQLSvc/[servername]:1433 These are actually registered to the Service account that we use for the SQL Servers. What is interesting is that I can't find the SPNs for the servers that are working anywhere. Any help would be appreciated! Edit: Also, another point to note is that if I try to add the user directly as a login into SQL server. I right click Logins and click Add Login then click search. I then type in [Domain]\[Username] and click check names. It validat

I have an .accdb with linked tables and use a login and password instead of windows authentication because we have several remote users. I have no trouble using this login and password using SSMS or my Access .adp project. I have successfully created the DSN-less connection sql server error for my tables using the code from Doug Steele’s site http://www.accessmvp.com/djsteele/DSNLessLinks.html but I am having trouble with creating the cached connection from MS Office Blogs http://blogs.office.com/2011/04/08/power-tip-improve-the-security-of-database-connections/ . I continue to get the following error: Connection Failed: SQLState ;28000', Server Error 18452, The login is from an untrusted domain and cannot be used with Windows authentication. This is at the point where the code tries to pass a test query to SQL: Set rst = dbCurrent.OpenRecordset(strTable, dbOpenSnapshot) And then when I click ok, I get the SQL Server Login screen with Use trusted connection checked (which I don't want) and a login ID auto-filled that is not the ID that I supplied via code. So, number one, why is Access/SQL continually trying to connect using windows authentication when I don’t want it to. Is there a way to specify NOT to? Trusted_Connection = NO doesn’t seem to work. Secondly (less importantly, but curious), the login ID is auto-filled but is not what I have for a login in my code. Why is SQL Server picking up a different login ID? Note: If I uncheck Use trusted connection and fill in the correct login and password (which the VBA code is receiving correctly – I checked using debug.print to check my co

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
