Resolution

Warning: SolarWinds strongly recommends that you create a backup of your database. This procedure can create permanent changes on your database. 

 

1. Check the ResourceProperties table in your Orion database. There should not be any records with ResourceID = 0.

You can use the following query to find any:

SELECT * FROM ResourceProperties WHERE ResourceID ='0'

2. Delete any rows/records with ResourceID = 0.  This can be accomplished via the following query **Note:  Please make sure you have a backup of your database before you perform any delete statements on the database**

DELETE FROM ResourceProperties WHERE ResourceID='0'
