Hi all. I’m having a problem with Network Performance Monitor 9.1 SLX. All nodes have disappeared from the Node tree. They are still in the data base and if I go into the custom property editor they are all still there. And they are on the web page and manageable there but not in System Manager. I have recently (two weeks ago) reloaded everything and put the data base on a SQL server but it had all been working for about a week and we came in Monday and it was all gone. Any ideas would be welcome.
