trying to connect to the sql server. 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 is a login failure, and is generally accompanied by more detailed information. –David Jan 4 '14 at sqlstate 28000 error 18456 16:03 And that more detailed info should be in the sql server error log.

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! –jlbruno Jan 9 '15 at 15:20 3 Thanks.

Password might be incorrect. Account may be disabled. No? Try next point.

If yes then check ifSQL Authentiction is enabled. If yes then check if you can create a new SQL Account and test it out. If it doesn't work than maybe service wasn't restarted (see previous link).
