HiI captured wait stats for 3 hrs and during the period I found that this wait stats "PREEMPTIVE_OS_AUTHENTICATIONOPS" number is v high.
Should I suspect this to any trouble with AD/DC? Or checking the avg ms/wait value of 1.2 is a good number?

I've read that a high wait here could indicate a problem with the domain controller, but I've never looked into it too deeply. What's your normal for this wait?
