I have NPM along with UDT and NTA. It seems that each of these individually has a function that allows for DNS Queries or Reverse DNS lookup.
The scenario is that I have a closed system. That is, there is no connection to the internet for security reasons. However, I have a DC and BDC that are running DNS these are the servers also running Solarwinds with FoE. What happens is we have a number of devices that are showing up in the NTA that automatically tries to resolve hostnames to IP addresses. Even when I disable this functionality (and the "reverse lookup" functionality on the main Admin Settings section) I still get a boat load of DNS queries from Solarwinds.
The DNS Root Hints file has a list of "last resort" servers to send queries to by default so it looks like after a couple of fails, the queries are sent to Japan or somewhere else for final resolution. Well, Security Team caught on to this and saw my servers sending a bunch of **** to Japan and had a cow.
How do I stop this madness? I don't need Solarwinds to query DNS and there are too many hosts (more than 1500) to put in a host file locally plus that wouldn't solve the issue with NTA anyway.
I am at a loss and three days in Solarwinds basically has punted the tech support case. Literally, the engineer said he was too busy and would get back to me.
Any help or direction would be greatly appreciated.
