Migrating from Mixed Mode AD FS to a Full Windows Server 2016 AD FS Farm

Chiyo OdikaADFS, WINDOWS SERVERLeave a Comment

I recently designed a solution to provide AD FS high availability for a client, using Azure IaaS and PaaS. This necessitated deploying Windows Server 2016 AD FS servers to a Windows Server 2012 R2 farm in order to align with desired DR testing plan, and accommodate downtime schedules. This article will review the specific steps for making the cutover from a mixed mode AD FS environment to a full Windows Server 2016 AD FS farm. It will not go into detail about installing the AD FS roles.  At the time of writing this article, adding Windows Server 2016 AD FS servers to a Windows Server 2012 R2 farm in a so-called “mixed-mode” scenario is fully supported, and you can subsequently … Read More

SCOM 2016 APM Linked to IIS Application Pool Failures.

Chiyo OdikaOpsMgr, SCOM1 Comment

****UPDATES: See update notes at bottom of the page. I recently encountered an issue where a client running a couple of SharePoint (SP) 2013 Farms was starting to see service failures across the board which adversely affected the availability of their sites. Prior to these failures, this client had recently upgraded their SCOM 2012 R2 environments to SCOM 2016, but there’s no definitive indication of causality as it relates to the SCOM upgrade. This article will provide an in-depth review of the issue, and a tested workaround. I’ll also update it with any new information that the Microsoft product group brings to light.   The Issue: Firstly we determined that the affected sites were based on legacy IIS application pools … Read More

SCOM 2016 Certificate Errors. Event ID 20049

Chiyo OdikaSCOM, WINDOWS SERVERLeave a Comment

In this article, I’ll review SCOM Certificate Event ID 20049. This error event can be seen during an attempt to initiate mutual authentication across untrusted boundaries such as in a gateway or workgroup boundary scenario. In SCOM, certificates will need to be used for mutual authentication between the management servers and any gateway servers/ agents when Kerberos-based mutual authentication is not possible. If there’s an issue with the certificate, mutual authentication will fail, and one of the errors you could likely encounter is as shown below: The event detail reads:  “The specified certificate could not be loaded because the key Usage specified does not meet OpsMgr requirements. The certificate must have the following usage types: Digital Signature, Key Encipherment.” This … Read More

OMS AD Assessment No data Found errors

Chiyo OdikaAZURE, Microsoft Operations Management Suite, OMSLeave a Comment

The Active Directory (AD) Assessment management pack is one of the many solutions available to users in OMS. This solution assesses the risk and health of your server environments on a regular interval and provides a prioritized list of recommendations specific to your deployed server infrastructure. If upon adding this solution to your OMS workspace, you encounter “No data found” errors, it’s a likely indication that you do not have the OMS agent installed on any domain controllers managed in your workspace. You can further verify this by using the following OMS search query and reviewing the results.

The search result detail for managed computers will indicate whether or not they meet the requirements for assessment by the solution. … Read More

SCOM 2016 – Creating Maintenance Mode Schedules

Chiyo OdikaOpsMgr, SCOMLeave a Comment

Firstly, this shall be short, but sweet. I won’t delve too deep. There’s already an entire bible, okay maybe half, on the subject. Find the authoritative Maintenance mode guide from Microsoft.   Maintenance mode in SCOM enables you to avoid any alerts or errors that might occur when a monitored object, such as a computer, database, cluster, etc. is taken offline for maintenance. Maintenance mode suspends the following features: (SOURCE: TechNet) Rules and monitors Notifications Automatic responses State changes New alerts SCOM 2016 extends the on-demand placement of monitored objects into maintenance mode that existed in previous versions of SCOM, and provides you with the ability to define schedules aligned with your service or maintenance windows, and automatically place monitored … Read More
