DNS Troubleshooting

Restricted or Managed DNS (Domain Name Servers) may cause slow connections when routing over the internet. Troubleshooting DNS is necessary If you are experiencing slow loading times, or if DNS is failing in the network Diagnostics. Troubleshooting Network Diagnostics

Managed Networks

Note: The network's IT Department may need to be contacted to allow network changes on a recorder.

If the ping does not come back successfully do not change the DNS to it. We recommend contacting the location's IT Department with our Network Requirements Document.
