Resolution

*Warning: Irreparable database damage can occur. This procedure should only be performed by
users familiar with SQL Server Management Studio. Databases should be backed up prior to
performing this procedure.*


To correct this issue we will need to correct or add these entries into the database manually.

First enable Maintenance Mode in ENM Configuration for ALL devices and then stop the Event Notification Module Services:
PL Alarm Sentry Host Service
PLActivePagerModule
PLOpcAELogger
 
Open SQL Server Management Studio and connect to the SQL instance containing the Event Notification Module Databases.
 
Browse to PLES_AEHistory Database and expand.
Find and open the table dbo.LG_OPC_SERVERS
Make note of the server listed in this table.  If all entries are NULL make note of this as well.


 
Browse to PLES_APM Database and expand.
Find and open the table dbo.AP_OPC_SERVERS
Make note of the server listed in this table.  If all entries are NULL make note of this as well.



If both tables only have null entries and, this is a standard install, then add the following information to both tables by clicking in the NULL cells and typing the entries below exactly as they appear.


 
If one table has a server entry but the other shows all NULL start with the table that has a valid SERVER_NAME.  Right click on the far left cell and select Copy.  Then go back to the table with only NULL available.  Right click on the far left cell and select Paste



 
To complete, restart the Event Notification Module Services listed above, wait 5 minutes for all entries to normalize and then disable Maintenance Mode for all devices in service.
