2010-05-06 17:21:22.30 Logon Error: 18456, Severity: 14, State: 6. 2010-05-06 17:21:22.30 Logon Login failed for user . Reason: Attempting to use an NT account name with SQL Server Authentication. [CLIENT: ]

The authentication mode is "Mixed". And its MS SQL Server 2008.

What might be the issue? Do you think the user name was not configured properly?

Is there any link available for giving the right privileges and configuring the user account? So that I can check the rights and privileges for the acc I am using...

thanks
