How do I delete the Wbem Inventory information from all the agents?
Run the following commands on the SQL server directly after taking a complete backup of the MDB database:
delete from inv_wbeminventory_tree;
delete from inv_wbeminventory_item;
This will delete all the information related to WBEM inventory from the database.
Note: Please make sure that you take a complete backup of the MDB before doing this operation.
