Notification Server 6.5 SP3 + R11
Recently encountered an old problem after running a console repair and a repair of the Notification Server. I was no longer able to drill down on the CMDB locaitons created for Asset Management under Manage > Asset and Inventory > Resources > Organizational Types > Location. The hierarchy of locations created was often 4-5 levels deep, going from North America > State > City > Office > Floor. In this particular case I was unable to drill down below the first level "North America"', to make use of the sub locations. When I would click on the + sign, it would just spin like it was trying to process the request and it would never come back with an error or timeout in any way. Initially we suspected there was an issue with the 6.5 console since we were able to drill down on the locations in the 6.0 console fine. After doing some additional research we discovered the KB article that was related to this, KB 35136.
For our configuration we needed to change the Render levels from the default of 1 to 5.
Keep this setting in mind if you ever need to run a repair of the Notification Server itself or the 6.5 console.
