Ie updated our 17.2 install too 17.3 and yesterday started the services and was happy to report everything worked.
However this morning I was unable to login to the server and was getting a username / password invalid error. I checked and all other users were getting the same.
I have stopped Appian (JBOSS --> Search Engines --> Services) and restarted server.
Now when I retry to start Appian, using start.bat -p passwoard -s all I'm not having much success. I can see the services looping during startup, and some do status change. However I get the following message :
notifications-email in DOWN state, REPLICA modeError running script: Failed to start the following engines: [execution00, execution01, execution02, notifications, notifications-email, process-design]
The following 9 services are running [analytics00, analytics01, analytics02, channels, content, download-stats, forums, groups, portal]
The following 6 services failed to start [execution00, execution01, execution02, notifications, notifications-email, process-design]
If I look in the Appian Log I can see the following message for the execution nodes :

pauls985 , Seems engines didn't shutdown properly last time.
Stop all the engines.(make sure all engines properly shutdown)
Run the checkpoint script again.
Start the engines and check the status.
If it didn't work, you need to repair your engines.
If you couldn't repair , I would suggest to perform upgrade again.
Hope it will help you..!!!
