ADFS Server Error 352 after installing KB4088787

I have a 2 server ADFS Farm with a Windows Internal Database on Windows Server 2016 hosted in azure. Yesterday after ADFS01 updated 2018-03 cumulative update for Windows Server 2016 the Service stopped working and showed the behavior as shown in https://hochwald.net/kb4077525-caused-issues-adfs-servers and it even took down ADFS02 which had already installed that update the week before. I tried restoring the server using azure backup from the day before yet the error persisted.

 

In the end I restored to a point in time were even 2018-02 cumulative update was not installed and everything worked although I also had to restore ADFS02 to the same point in time to get it to work, too.

 

Ironically, the update I installed was the one that should have fixed an ADFS error caused by 2018-02, which didn't occur in my environment to begin with.

 

Since I am using update management in azure how am I supposed to get to a current build without destroying ADFS? Should I wait for the next CU?

 

I am afraid of reapplying the updates since I fear they will break my servers again
