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 alia
