Microsoft SQL Server Error: 18456 Can anybody tell me what the error code means? sql-server connection error-code share|improve this question edited Jun 29 '15 at 13:28 ughai 8,37231238 asked Jan 4 '14 at 15:43 merazuu 3933615 5 A cursory search seems to indicate that the error code login failed for is a login failure, and is generally accompanied by more detailed information. –David Jan 4 '14 at 16:03 And that more detailed info should be in the sql server error log. The number itself deliberately doesn't tell you much, so crackers can't use it for clues on where their attempts are going wrong. –Tony Hopkinson Jan 4 '14 at 16:10 8 @David if you see a duplicate question in SO, then mark this as such. Just because the answer is easy to come by, doesn't mean it doesn't belong on SO. This is the first hit on Google after all :). –Josh Noe Feb 24 '14 at 19:52 add a comment| 7 Answers 7 active oldest votes up vote 103 down vote accepted if you're trying to connect using "SQL Server Authentication" then you may want to modify your server authentication ; Right click server and click properties go to security page under Server authentication, choose the SQL Server and Windows Authentication mode radio button click OK restart your server this might help you ! share|improve this answer answered Apr 30 '14 at 18:35 Aringan 1,173378 Exactly what I needed, thank you! –jlbr
