Hi,
Recently, I've seen a lot of following sql server
log messages.
-----------------------------------------------------------
"Login succeeded for user 'sql_user_name'. Connection:Non-
Trusted.
-----------------------------------------------------------
This messages repeatedly appear multiple times even within
a second.
Does this mean some non-trusted user successfully
connected to our server?

I've serched the Internet a while for this problem,
and I found out that it might happen when
the Security Auditing is Enabled.
(Microsoft Knowledge Base Article - Q288426)
And the article said that this problem supposed
to be fixed with the latest servece pack.

We have the Microsoft SQL Server 2000 Standard Edition
with Service Pack 2, but still have this problem.
Does anybody has the same messages?
Any advice would be helpful.

Thank you,
