How to solve the event ID 27235 on VMM (System Center Virtual Machine Manager).


In my customer the environment was working just fine, and on a Wednesday morning the following error started to display when creating some objects in VMM. After some troubleshooting, the issue was that the Server was up-to-date with the latest Rollup Update but not the VMM Console.


That being said, the solution is easy, make sure that you update the VMM Console and the error will go away. It is crucial to update all the infrastructure of VMM (Console, Server and agents) to the same version to keep consistency among VMM components.
