The user is not associated with a trusted SQL Server connection. You should create new DSN with changed Authentication Mode from Windows Authentication Mode to SQL Server Authentication. Then specify login and pass for connection. This login should be added on SQL too. share|improve this answer answered Mar 12 '15 at 23:25 cypizek 1684 the problem is like that: when i connect with sa in the client computer, i can connect!! but when i connect with a simple user who use Windows Authentification, connection is failed!!

Perhaps they are using a special account that is local to the OS, but is not a domain account also see the link below ;) http://blog.sqlauthority.com/2007/04/14/sql-server-fix-error-18452-login-failed-for-user-null-the-user-is-not-associated-with-a-trusted-sql-server-connection/ 0 Pimiento OP Sukh May 24, 2011 at 12:20 UTC No, user using the domain account. It works sometime and sometimes it didn't work . If you log off and log back in , it solves the problem. but its not permanent fix. Somehow useraccount get accepted as Local account but its domain account 0 Habanero OP David1618 May 24, 2011 at 1:12 UTC Type specifying the domain and user explicitly and see if you can get to 100% successful logins. ex.: username/domainname I had a heckuva time with my SQL 2008 machine not at all liking domain accounts. This might possibly have been because I login with a normal user account (I like to call them 'Mortal' accounts) to the workstation but when I connect to the SQL server it is with a different, admin (I like to call them "God" accounts) account. After awhile I gave up and just used a SQL local account.
