Kenneth Fisher diagnoses a misleading error:

In general, the errors SQL gives are highly useful. Of course every now and again you get one that’s just confounding. The other day I saw the following error in the log:

Login failed for user ”. Reason: An attempt to login using SQL authentication failed. Server is configured for Windows authentication only. [CLIENT: ]

But Kenneth shows that the server is configured for SQL authentication as well as Windows authentication.  Click through to see what gives.
