Ruling out SCOM notifications as the cause of SCHANNEL events

 

 

Still getting SCHANNEL error events and want to rule out SCOM

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 https://support.microsoft.com/en-us/help/305088/schannel-error-message-36871-when-receiving-an-ehlo-smtp-command

Do the events correlate with emailed alerts?

Associating MPX files to Notepad++ for MP Fragment Authoring

holyschnikes

Sometimes it’s shocking when you make a simple change that helps you do something easier.

For the UNIX guys in the house, using VIM, GVIM, VIMRC, all helped back in the day to make sure you closed your loops, true tests, etc.

If you use Notepad++ like I do, let alone if you’re creating MP fragments, it helps for the easy color coding.

SO, do you always open the .mpx file and then click on Language, XML?

Time to add the file type to the Style Configurator in Notepad++

In Notepad++

Click on Settings

Click on Style Configurator

Highlight XML in the language column

Add .mpx to the ‘User ext. :’ section

Click ‘Save and Close’

notepadaddmpx

Open up your next MP fragment

Spend your time updating your XML not clicking to format the file!

Save clicks!
