SQL Server Log File Not Accessible, Dbcc Not Really Useful, How to Analyze?

I'm trying to track down why a db query got screwed in SQL Server. rndbcc log(mydb,2) is not filterable by date(?). And the ldf file I can't access directly without going through 2 layers of bureaucracyrnAny suggestion? How to tackle with it?

not sure, I know when stored proc was called, from my webserver log, now trying to track it down on db logs.

I got the solution by applying SELECT * FROM fn_dblog(null, null)n
