Enable or verifiy that Login auditing is enabled. In Server Properties
select 'Failed logins only'.

The information will be recorded in the SQL Server error log.

You can also create an alert looking for error number 18456 and get notified
by e-mail.

I want to be able to track when somebody tried to log in with an invalid
userid or password. How do I do this?

TIA - Jeff.

Alternatively, you can set up a SQL Trace to audit event class 20 for "Audit
failed logins". This would give you a bit more info. For instance, you can
include the data column 'ApplicationName" to capture the name of the app from
which the failed login attempt is made.
