Malicious user erase a table

Please. I need to find the way to identify a user of the database that erase
a table. Since I can do it ?Hi,
Try to read the Trasnaction log using Loagexplorer (www.lumigent.com) .
Otherway is to enable the profiler.
Thanks

your security is set up right, that should narrow it down considerably.

only chance would be to get a log reading program that allows you read the
transaction log.

are malicious?
When did this occur? If it happened like less than an hour ago, then perhaps
they are still logged into EM or QA. Go into Enterprise Manager and look
under Managment\Current Activity\Process Info. This lists all current
connections to the server (including login name), and clicking on each
process will show the last SQL batch command they executed.

e
transaction log is *the* tool which gave you any hope of finding who emptied
your table.

configuration is pretty wack. Restore from backup and take away the rights
to "delete tables" from users who don't need it (more often than not in a
production environment this will be almost *all* of your users).
