Using the ConfigMgr AdminService to Retrieve BitLocker Recovery Keys and Triggering Key Rotation

The Key to Success is Knowledge Recently Garth Jones accused me of knowing something that I knew nothing about and I was very offended by that. So much so, that when Bryan Dam came to me demanding to know the keys to BitLocker keys in ConfigMgr, I decided I should figure it out. So I did. Here’s what I know now: Keying in on the Issue When trying to automate processes around ConfigMgr, there are Ways to do things then there are Supported Ways to do things.

CMPivot Reference

The following examples were compiled from the CMPivot Home screen examples and the PowerShell equivalent commands were extracted from the CMPivot PowerShell script that is copied down locally to C:\Windows\CCM\ScriptStore.

When VDI and ConfigMgr Co-Management Collide

Before we begin, here are some notes about persistent and non-persistent VDI that will likely give you nightmares: Intune doesn’t support non-persistent VDI Azure Active Directory only supports Hybrid Azure AD Join for non-persistent VDI ConfigMgr recommends limiting client functionality on non-persistent VDI but there is no mention about the impact of Co-Management on these devices.

Using ConfigMgr Run Scripts and Microsoft Quick Assist to Repair a Broken Domain Trust Relationship

Recently one of our sites began having some issues with domain joined devices losing their trust relationship with Active Directory. While some users were able to log in with cached credentials, we had no easy way to get admin credentials to repair the domain trust.

Windows 10 Feature Updates – Testing the /MigNEO Disable Parameter

Over the past few weeks I’ve been testing re-writing my Windows 10 Feature Update repo to make it easier to implement - if you haven’t tried it, go check it out. Just follow the readme in the repo https://github.com/AdamGrossTX/Windows10FeatureUpdates. During the re-write I was reminded that there were a few command line parameters that I hadn’t experimented with. One of them is /MigNEO which only has a Disable option.

Troubleshooting ConfigMgr Enhanced HTTP and Azure Directory Group Sync

Today I got to help my buddy Adam Juelich with getting ConfigMgr Azure Directory Group Sync working. It’s an awesome new feature that allows you to sync ConfigMgr collection memberships to your Azure tenant. Adam had followed all of the steps and ensured that prerequisites were all configured properly but sync would never work. Over a Teams meeting we double checked everything and walked through Ronny Dejong’s (He covers pretty much all of troubleshooting steps needed for this!
