setup a trace in Profiler to collect failed logins with these columns
needed: database ID, host name, login name, NT username, ApplicationName.
Analzy the trace after some failed login may help. My box had failed logins
that later I found out a report queried ALL user databases instead SOME
databases.

hosted on our application servers.

occuring events. The databases we are seeing this behaviour on are db's that
see alot of activity. The system on a whole is pretty active as it is our
primary database server hosting about 50 or so databases. In terms of why
this is happening, we are very stumped. The login info specified in the code
of these sites are consistenly defined and have the correct login
information so it is not that we are supplying incorrect login information
to the server otherwise these sites would not work at all as they are
database dependant. So I was wondering, what can cause this? Is this a sign
of some a machine that is overworked? I would appreciate any help and input
you folks may have.
