Hello all,
I had two Exchange 2016 servers in my infrastructure and I started to upgrade them to Exchange 2016 CU3.
One of the servers has been updated successfully, but the second one ran into a problem at 'Client Access Front End service' stage.
You can see the CMD output below.

The Exchange Server setup operation didn't complete. More details can be found in ExchangeSetup.log located in the
:\ExchangeSetupLogs folder.

At this stage I cannot do anything with the server, and /owa is not working anymore. It seems that I have a corrupt installation.
Do you have any ideas how can I solve the error and ran the installation task again?
