Monitoring Invalid Logins

I have a feeling someone is running a brute force password program against my
SQL Server. How can i see how many invalid attempts there was? And from which
IP Address? sp_monitor does not give me much information.
Thank you!
You can try a network sniffing utility like Network Monitor.

|||You can log failed logon attempts to the SQL Server log. Right-click the
server in Enterprise Manager and choose properties. Go to the security tab
and check the appropriate option under Audit level. Failure is I think the
default anyway. You can check the SQL Server logs, under the management
folder for the results.
From there you can see how many attempts there were, and against which
account, but that's about all the information you get. If you want more
information, you can set up a SQL Profiler trace, using the Audit Login
Failed Event.

Monitoring & Starting Distribution Agent thru program

Do any one know how to detect a distribution agent failure thru program. Is
there any way to start it programmatically.
Any help would be great
Kumaresh,
how are you setting off the distribution agent? If it is through programming
the activeX control, you could then have a look at the replication errors
collection. This example applies to merge, but AFAIK it's much the same for
transactional.

Alternatively you could look at MSdistribution_history and MSrepl_errors
tables (or the job's history directly)

|||Thanks for your valuable comments.
I have set the replication through the SQL Server Enterprise Manager.
But the client complains that they saw the replication failure only after
one day.
And then after they had to set the replication again.
Hence i thought of running a schedular program which checks for replication
and start it if it had a failure.
I also will be very happy if u could suggest or post some guide lines to
proceed
thanks once again

to let the client know, you could use the alert: 'Replication: agent
failure' and have an email sent from there.
Actually, what I do is send notification directly from the replication job
belonging to the distribution agent with a specific message - in my case I
only have SMTP, so I use an additional step in the distribution agent's job
which is reached only on failure of the main step but if you have MAPI
integrated, then you can just add the On Failure notification like in any
other job. HTH,

|||Thanks Paul, That was very near to the solution expected.
But i also wanted to know is there any way by which i can handle it by myself,
leaving the client undisturbed. Say for example running a scheduled program
or some thing similar to that. so that i start the relpication without the
intervention of the client
Any suggestions would be great

this will give you any replication errors in the last 24 hours for a
specific replication job. It hope it's OK for your purposes.
SELECT DISTINCT
MSdistribution_agents.name,
MSdistribution_history.runstatus, MSdistribution_history.error_id,
MSdistribution_history.start_time,
MSdistribution_history.comments
FROM MSdistribution_agents INNER JOIN
MSdistribution_history ON MSdistribution_agents.id =
MSdistribution_history.agent_id INNER JOIN
MSrepl_errors ON MSdistribution_history.error_id =
MSrepl_errors.id
WHERE (MSdistribution_agents.name =
N'PC-TEMPLATE-Northwind-PC-TEMPLATE-2') AND
(MSdistribution_history.start_time BETWEEN DATEADD(dd, - 1, GETDATE()) AND
GETDATE())
Rgds,
Paul Ibison
|||Thanks Plan
Here is the way am proceeding. First am gonna write a trigger on
MSdistribution_history table to check for errors
If any error occurs, then a COM object is called to delete MSREPL7 table
created in oracle database
Is this a reliable solution to proceed with.
Also how can a distribution agent be restarted within a trigger
Any help would be great

you won't be able to make a trigger on this system table, but you could
schedule a job to run once a minute to poll the table.

|||Thanks paul,
I also want to know if i could start the replication from T-Sql
Any reference articles would be very helpful
