Happy Friday to all.
Currently looking at our worst event offenders on our domain. Currently seeing a ton of Event ID 18456 this is related to a SQL account failing to login to the DB. Across about 5 servers I'm seeing about 4-5 logged a second. :/ Weird thing is (at least to me) that the events show a domain login not being able to access master (default DB for SQL). I tried giving datareader and datawriter roles but these events are still being logged. Do I need to make this account dbo or do I have another option? Currently running SQL 2012 SP1.
Thanks in advance,
Zach
