Can someone help me out in figuring out who changed the maintenance plan schedule? Ten days ago this job started running every 20min and need to know who set it up to prevent it from happening again. The log files only go 1 day. Please help.
Are you saying the scheduled job history only goes back 1 day or your SQL Server log only goes back 1 day. Hopefully you are only talking about the scheduled job. Review your SQL Server log and you should see the change in there. You might also take a look at who all has the rights to make such a change and approach them individually. The number of people that can make this type of change on a production box should be FEW.
