Login failed for user 'sa'. Reason: Not associated with a trusted SQL Server connection. SQL 2000
From Wiki
I am seeing a ton of searches reaching Lessthandot from Yahoo and Google with this search “Login failed for user 'sa'. Reason: Not associated with a trusted SQL Server connection.” So this is what causes the problem: your SQL Server has been setup with windows authentication only. In order to make it mixed mode authentication right click on the server name in enterprise manager select properties and click on the security tab. Select SQL server and Windows (see picture…) and that will fix it
For the SQL server 2005 version go here: Login failed for user 'sa'. Reason: Not associated with a trusted SQL Server connection. SQL 2005
