CMPivot and SMB1

Ned Pyle has ensured there is a Event-log that details any attempts to communicate with SMB1 (incase this still is enabled on your endpoint). It exists both for SMBServer and SMBClient

See his great post for specifics regarding the event;

As of Configuration Manager (or MECM) 1910 you can utilize CMPivot to query all Event-logs (previously only a subset where available is only the Get-WinEventLog cmdl:et was used) – including SMBClient/Audit.

Sample query – summarized the number of events 30 days backwards per client

WinEvent('Microsoft-Windows-SmbClient/Audit', 30d) 
| where ID == 32002
| summarize count() by Device

Sample query – device, date and message

WinEvent('Microsoft-Windows-SmbClient/Audit', 30d) 
| where ID == 32002
| project device, datetime, Message

In addition you can create a collection of the clients you found;

Or if it needs to be pretty;

WinEvent('Microsoft-Windows-SmbClient/Audit', 30d) 
| where ID == 32002
| summarize count() by Device 
| render barchart with (kind=stacked, title='SMB1 Events', ytitle='Events')

Troubleshoot Office crashes – quick guide

Wrote these notes on how so many Office issues were solved. Sadly – this still applies – and a recent thread from Twitter reminded me that it might be useful.


Temporarily set the printer to ‘PDFCreator’ as default printer

Verify if the issue is resolved


Start the application in safemode or without addins


winword.exe /a

excel.exe /s

outlook.exe /safe

If the application doesn’t crash if the Office application is started without addins, verify what addins the user has installed.

Narrow down the issue and attempt to identify which addin is causing the crash

You can review installed addins by selecting;

File -> Options

Review the Addins-option

Temporarily disable addins by using the Manage -> Go.. at the bottom

Some addins may require that you temporarily start the application as Administrator.


Close all Office applications

Registry issues

Try to temporarily rename the settings for a specific application in registry

Open regedit.exe

Locate the;


Locate the crashing application;

Word, Excel, PowerPoint

Sample Path;


Rename the registry key for your application – using Word as a sample;


Retry to start the application

Repeat the same steps for the specific application


Locate the specific version;

12.0 -> 2007

15.0 -> 2013

16.0 -> 2016

If the issue is not resolved, rename the version registry key – using 12.0 as a sample;


If the issue is not resolved by temporarily renaming registry keys it is recommended to restore all registry-keys to their original name


You can temporarily rename application specific folders for Office-applications. Suggestion is to rename the below folders to _temp and verify if the issue is resolved
