I was unable to add a new login for a local windows user on a local sql server just because of case. The Sql Server management studio process would always give my user login like this : AMITY\Dave. In fact, the right case is Amity\Dave.By executing sp_grantlogin "Amity\Dave" it worked fine.Bad GUI tools don't ease the use at all.DavidReply Alice April 30, 2009 12:51 amHi Pinal,I got this err when I tried to manually change the Window group name after the physical server got renamed.After renaming the server, I use sp_dropserver and sp_addserver to bring SQL in sync with the new server name. Then I restart SQL Server. Everything seems to work fine.

The SQL instance is intended as back-end support for Sharepoint WSS 3.0 Extranet traffic. The SQL instance is behind our firewall in one domain while the WSS Extranet is in a DMZ within another domain. I've successfully done this before with SQL 2000 and WSS 2.x.The problem I'm having currently is that when I try to add our Extranet support login to the SQL Instance I get the following error: Create failed for Login 'domain\login-name'Windows NT user or group 'domain\login-name' not found. Check the name again. (Microsoft SQL Server, Error: 15401)o The SQL Server can ping the DMZ Domain Controller (and can be pinged from the DMZ Domain Controller.o I can add the target DMZ windows account to the SQL Servero I can add logins from other (and local) domainso The collation sequence on the SQL Instance is: SQL_Latin1_General_CP1_CI_ASo I've checked for duplicates in the master..syslogins (clean)I've looked around on the web and found others having this issue but no definitive answer.
