Join SolarWinds VP of product management Brandon Shopp to discover how the new SolarWinds® Server Configuration Monitor is designed to help you.

- Expand advanced
- Increase Polling Timeout to something like 300s or 450s
- I would also suggest increasing the Polling Frequency to every 15 minutes rather than every 5 minutes.
