You can increase the number of nodes that load in each batch by editing \Inetpub\Solarwinds\Orion\Nodes\Controls\NodeTree.ascx. Around line 234, there's a place where it says RowsRange="25". Try increasing that number and see what works.
Can you double check that file name and location again? I am running version 9 and don't find a file by this name in that location.
I am running Orion 9.0 SP1 and I can confirm that file name and location are correct. Make sure you go to that path on the appropriate drive letter for your installation. This simple change has made it much easier to manage nodes via the website!
Hmmm. I have no path Inetpub\Solarwinds\Orion\Nodes\Controls\NodeTree.ascx.
I have the following: Inetpub\Solarwinds\Orion\Controls. But, I also do not see the NodeTree.ascx file in this location.
I find NodeTree.ascx in the following location:
Inetpub\Solarwinds\Orion\NetperfMon\Resources\NodeSummary. The file does not have 234 lines.
What's up?
