'Controller Web' Windows services keep shutting down, when using Windows Server 2019 (unsupported for Controller 10.3.1 or 10.4.0)

Troubleshooting


Problem

Customer installs Controller on a Windows 2019 Server.
  • IMPORTANT: Windows 2019 is not officially supported for Controller 10.3.1/10.4.0. See link at end of this Technote for more details.
I.T. administrator starts the relevant Controller Web windows services:
  • IBM Cognos Controller Web
  • IBM Cognos Controller Web UI
Initially the service seems to work OK. However, after approximately 1 minute, the IBM Cognos Controller Web windows service shuts down.

Symptom

The IBM Cognos Controller Web windows service stops approximately 1 minute after starting.
More Details:
After starting the IBM Cognos Controller Web windows service:
  • The following process is executed:  prunsrv.exe
  • This causes the following process to start:     Javaw.exe
After about one minute:
  • the prunsrv.exe process closes
  • This leaves just the Javaw.exe open/running.
This will cause the  IBM Cognos Controller Web to look like it is not started.
  • However, Controller Web itself still works (because it is contained within the Javaw.exe process).
For the record, if everything is working correctly (normally) then it should look like this:
Task manager prunsrv
This shows 2 prunsrv.exe processes opened/running:
  • One for fcmweb
  • another for frontend and the javaw.exe
