Ruling out SCOM as the cause of SCHANNEL events


Ruling out SCOM notifications as the cause of SCHANNEL events



Still getting SCHANNEL error events and want to rule out SCOM

Management pack SQL events

SCHANNEL ciphers debugged


What command Channels are setup for notifications?



Validate Subscriptions aren't the cause for email/text

Exchange 2013 and above typically use S/MIME to digitally sign/encrypt messages


Email communication can cause System 36871 events

Do the events correlate with emailed alerts?
