Is this possible? SQL Server 2000 Write times

No timezone discrepancy, they did it in our labs here at our institution. I
didn't think so, but had to ask. What logs would i search and what would I
look for?

I would not expect that sort of delay. 9:00am/9:59am, could there be a
time zone discrepancy? Can you use your website logs to determine when
the user made their submission?Shawn Ferguson wrote:

That would be a question for your web server folks. Your web server
should maintain logs of the visits to the web site.|||> No timezone discrepancy, they did it in our labs here at our institution.
That doesn't mean that some computer along the way doesn't have an incorrect
timezone and/or system time specified!

Is this a new SQL BUG

For the last two days, I have been checking my SQL Server error logs and this is what I find common on all the SQL Servers, with Audit Login options ON: Login failed for 'A', Login failed for 'B', Login Failed for 'C'..all the way to the last login.
For each login defined in the SQL Server, I'm finding that the error message is getting generated 18 times. My guess is that someone is trying to run some kind of code.

Any experience?Make sure you don't have any easily guessable accounts, and DEFINITELY, - change your SA password. This is not a bug (unless you don't have the latest security patch from M$, in which case it is and has been fixed). Whatch out, someone is after your server.
