We've been having multiple errors with on our performance report.
User Name:	"COMPUTER NAME"$
User ID:	"DOMAIN"\"COMPUTER NAME"$
Service Name:	krbtgt/Domain.local
Pre-Authentication Type:	0x0
Failure Code:	0x19
Client Address:	"COMPUTER IP"
I had seen something that said you might get these errors when the domain isn't all caps. It is all caps under "User ID" but not "Service Name" as described above. Is that why I am getting that error and if so why did it just start this week? We had a server crash this weekend that we think was from someone trying to hack the administrator account, is that maybe why?
