All TR6 workstations require the Total Response - Launcher Service (a standard Windows Service) to run in order to login:
All TR6 Servers require an additional service, Total Response - Login Service (also a standard Windows Service):
The TR Server service communicates with the SQL Server database continously, providing updates about the login and status of the TR workstations.
Issue
If the TR Server loses the ability to reconnect or update the database, the Service may quit.
This could occur in the event of temporary network issue or significant performance degradation of the SQL Server.
Solution
Windows can act as a watchdog to auto-restart a service. Issue the following commands in a Administrator PowerShell:
sc failure "TotalResponseLoginManager" actions= restart/5000/restart/10000/restart/30000 reset=86400
sc failure "TotalResponseLauncher" actions= restart/5000/restart/10000/restart/30000 reset=86400
The first crash will restart after 5 seconds, second 10 seconds, third 30 seconds. Intervals can be changed. It is no substitute for identifying the root cause on the SQL Server.
