The weekend I thought to run some auto discoveries (because that's the clever thing to do) ran them the weekend. Checked Sunday afternoon (as some changes were being implemented on the afternoon and I was on call) and nothing was added. I thought that was a little weird so this morning I tried adding a couple of nodes manually as I then have control over what I see and both tests failed. So I had a look at the SNMP settings (I did a GPO to change all of the SNMP settings) as you can kinda see (I removed the IP addresses) the strings are the same (as well as the IP address') as the old server. I know my GPO has worked as the old solarwinds has not emailed about any nodes have stopped responding.
Which is why I am thinking, it might be the networking rules, but that can also be dismissed as I can ping to the two nodes from my new box.
Below is a screenshot from my two boxes. One is fine (the old solarwinds), but the other isn't (new). Would anyone have any ideas about this?:
