I'm not sure when this started, but I noticed earlier in the Health Monitor that the Failed Logins Per Hour alert was tripped, and reviewing the log shows that a printer object (?) is listed as the User. I was working on this particular printer earlier today (flaky Jet Direct card, but that's another story) but I don't see how any of my actions could produce this effect. Printer has been working fine all day since, but the log shows it trying to "log in" every 3 minutes....?
