Question: Alarms are being displayed on the alarm page with a user name of SYSTEM (in the UserName and FullName fields) and not the name of the logged in user. What is going wrong? 

Some alarms will have the user name of SYSTEM and not the logged in user name because these alarms have been generated by the system. All new alarms have the user name SYSTEM, because the operator did not generate the alarms - they were generated by the plant. The user name will only be changed to the logged in operator if that operator does some operation on the alarm. For example acknowledging or disabling the alarm.

The alarms are processed on the alarm server. (Operators are only clients logged into the server.) For example, when you have two operators logged into the same alarm server, and an alarm is generated, then who does the alarm belong to? As you can see in this case the alarms don't belong to either of the operators until an operator does some operation on the alarm.
