Updated NOSC Daily Tasks Summary

Latest round adds simplification of SCOM agent workflow errors, adding the offending computer with the SCOMAdmin DailySummary alert details.

Offending alert examples from multiple customers

MSSQL on Windows: SQL Server has failed to allocate sufficient memory to run

Alert generation was temporarily suspended due to too many alerts (event ID 5399)

PowerShell was dropped

Expression Filter Module Failed Initialization (group regex errors)

The November pack updates add TicketID field to the SCOMAdmin, Daily Summary, Logical Disk report, and Alert updates reports. This is invaluable when integrating service management (ITSM) system events/alerts/incidents into your monitoring. Lastly, visibility into created incidents is key to business issues (see the AlertUpdates workflows).

STIGs for SCOM FIPS compliance on Windows

What does your mind link to with the FIPS acronym? FIPS makes me think of the movie Greyhound where Tom Hanks says LT Flipper, instead of Fippler, all that said being ZERO to do with resolving ‘STIGs for SCOM FIPS compliance on Windows’

The biggest hurdle to ‘STIGs for SCOM FIPS compliance on Windows’, is obtaining the files. The current bundled SCOM ISO’s since 2012 SP1 do NOT contain the gacutil, and cryptography DLL files, to resolve STIG V-220942 (win10), V-226335 (Server 2012/2012R2), V-73701 (Server 2016), V-93511 (Server 2019), V-254480 (Server 2022). As much as we want to resolve FIPS ‘STIGS for SCOM FIPS compliance for Windows Server’, gotta start with the finding relevant files. My thanks to Nathan Gau, Tyson Paul, and Aakash Basavaraj, for their involvement and clarification.

Install DLL for STIGs for SCOM FIPS compliance on Windows

Time to mitigate!

Let’s begin to fix the SCOM Web Console role servers (possibly SQL SSRS and PowerBI Report Server included) for resolving multiple ‘STIGs for SCOM FIPS compliance for Windows Server’. Blog post applies to multiple STIG(s) including STIGs V-220942, V-226335, V-73701, V-93511, V-254480

Download files

Whether from blog download link, or if you have the old ISO’s to obtain the DLL, and server ISO for gacutil , or myvisualstudio.com link

Download SCOM ISO from my.visualstudio.com/Downloads?q=operations

If you downloaded from my.visualstudio.com, extract from ISO.

Copy files to IIS role servers (SCOM web console, SSRS, or PowerBI report Servers) to setup files for FIPS compliance.

Download the DLL to the SCOM default folder –

Best practice is SCOM Default folder on non-system disk @

D:\Program Files\System Center\Operations Manager\Server

Update the registry on relevant servers

Registry key update is required to mitigate ‘STIGs for SCOM FIPS compliance on Windows’.

STIG states to create Enabled Key with a value of 1 in HKLM:\SYSTEM\CurrentControlSet\Control\Lsa\FIPSAlgorithmPolicy\

Verification via RegEdit (registry editor)

Display of regedit for the FIPS enabled key

PowerShell Verification:

$RegPath = “HKLM:\SYSTEM\CurrentControlSet\Control\Lsa\FipsAlgorithmPolicy”

[string]$FIPSEnabled = (Get-ItemProperty -Path $RegPath -Name Enabled).Enabled

if ( $FIPSEnabled -eq 0 ) {write-host “FIPS disabled” }

Example Output

PS C:\> $RegPath = “HKLM:\SYSTEM\CurrentControlSet\Control\Lsa\FipsAlgorithmPolicy”

PS C:\> [string]$FIPSEnabled = (Get-ItemProperty -Path $RegPath -Name Enabled).Enabled

PS C:\> $FIPSEnabled

PS C:\> if ( $FIPSEnabled -eq 0 ) {write-host “FIPS disabled” }

FIPS disabled

PowerShell to set the registry key:

Blog link

$registryPath = “HKCU:\Software\ScriptingGuys\Scripts”

$Name = “Version”

$value = “1”

New-ItemProperty -Path $registryPath -Name $name -Value $value `

-PropertyType DWORD -Force | Out-Null

Reboot web console servers to verify web console functionality!

This concludes resolving ‘STIGs for SCOM FIPS compliance for Windows Server’

V-237434 SCOM Web Console SSL Settings

No Soup for you! You have STIG findings :-( — No Soup for you! You have STIG findings 🙁

Much like the character from Seinfeld, finding out that the ‘V-237434 SCOM Web Console SSL Settings’ is NOT STIG Compliant (STIG’d), is just as tramatic as being hungry, and told ‘No soup for you!” With all the many STIG findings, here’s a quick and dirty way to resolve the finding.

Vendor documentation

STIG V-237434

SCOM Web Console Authentication on learn.microsoft.com

Kevin Holman SCOM QuickStart guides for SCOM 2019, SCOM 2022

V-237434 SCOM Web Console SSL Settings

STIG V-237434 requires trusted CA SSL certificates. Previous July blog posts are related to the effort to secure the SCOM web console. The redirect post forces HTTPS, complimenting this STIG finding. As the STIG states, remediation verification that IIS web site binding is HTTPS, and remove HTTP.

Remediate SCOM servers with Web Console role

Assumption = SmartCards are used for authentication, this part is applicable, otherwise skip.

RDP to server, connect to IISManager

Expand IIS Server > Expand Sites > Expand Default Web Site

Click on SSL Settings

If the menu is greyed out, follow the SCOM WebConsole settings blog to setup the SSL certificate. Once complete, proceed below.

Click on SSL Settings > Check box to ‘Require SSL’

If menu is NOT greyed out, click radio button to ‘Accept’ client certificates

Click Apply

IIS Manager, Default Web Site, SSL Settings default when NOT running SSL certificate and bindings

Click on Default Website on left hand pane

In the Actions Pane (right hand side), click on Restart to restart the IIS website

Restart IIS website from IIS manager actions pane

IIS Website bindings

Next pieces is to verify the SSL HTTPS binding is setup correctly. In case you got disconnected, or rebooted the server

RDP to server, connect to IISManager

Expand IIS Server > Expand Sites > Expand Default Web Site

In the Actions pane on the top right, click on Bindings

IISManager, Default Web Site, Actions Pane, Bindings to setup HTTPS and remove HTTPS

Kevin Holman’s QuickStart blog(s) for SCOM 2019, SCOM2022 setup default HTTP binding (i.e. NO SSL cert configured)

Default website, Bindings selection showing HTTP if SCOM quick start followed — Default website, Bindings selection showing HTTP if following SCOM quick start

If HTTP ONLY, click the Add button

Change dropdown for Type to https

Enter Host Name

Click Select to choose the SSL cert

Click OK

Adding HTTPS Binding with server name, SSL cert drop down and selected

Verify SSL certificate added

If you have the binding above, change your STIG CKL finding and document as NOT a finding, for V-237434 SCOM Web Console SSL Settings!

Have fun

Do you feel like a mechanic having to jump start the agent configuration like a dead car battery? Assuming the Agent is already installed, you can configure the SCOM agent via PowerShell. Even better when you can PowerShell remote to multiple systems. I hope the PowerShell commands below help you master PowerShell to configure the SCOM side of the MMA agent (house).

ConfigMgr SMS role alerts

Microsoft Endpoint Configuration Manager

It’s that time to figure out the ConfigMgr SMS role alerts – If you are monitoring your SCCM/MECM environment, then you get role failure alerts. Many times, the Operations Helpdesk, NOSC, NOC, SOC, etc. will get alerts when various roles fail on the Configuration Manager platform. The common ask is why, what do you see, etc. Much like Exchange, ConfigMgr internalizes the checks that are seen in the console as registry keys or events documenting said degraded component/feature. Helping the MECM administrator understand the failure is key to decoding how to notify administrator, and when the helpdesk needs to act on ‘ConfigMgr SMS role alerts’.

Example – MECM/SCCM looks at replication probe action state $Config/RoleName$

Example MECM Service Monitor for role alerts

The role check is based on a variable of the RoleName in a registry key that the application updates.

This is the origin of ConfigMgr SMS role alerts

HKLM:SOFTWARE\Microsoft\SMS\Operations Management\SMS Server Role\$Config/RoleName$\Availability State

Decoder ring:

1 is critical state

2,3,4 are warning states

If more details are needed, download SCCM/MECM Management Pack for SCOM here

Use Tyson’s SCOM Helper pack to unseal, and inspect XML.

Once you know the origin of the ConfigMgr SMS role alerts, you can begin tuning the MECM alerts to your environment. Understanding role alerts will help both teams understand MECM application health. First, use MECM application health to trend alerts/outages. Second, leverage maintenance mode schedules, or MM scripts to NOT monitor for common administration tasks. From my experience, the alerts are the result of MECM Admins maintaining the application – common actions like building application/package lists, cleanup actions, site maintenance, backups, etc. Lastly, set up a subscription to notify after the tuning discussion. See my blog on building a subscription for more details.
