Is the DNS server functioning correctly?

 Check the DNS server settings to make sure the server is functioning
correctly as a DNS server.

If applicable, ask your network administrator to ensure that the DNS
server can be used.
What to check on the network as a whole
Does your network include a router or similar device that serves

as a gateway?
 If applicable, ask your network administrator for the network gateway
address and enter it on the camera (p.17, 97).

Make sure the gateway address setting is correctly entered on all
network devices, including the camera.
23: Duplicate IP address
What to check on the camera
Is another device on the camera network using the same IP

address as the camera?

Change the camera's IP address to avoid using the same address as
another device on the network. Otherwise, change the IP address of
the device that has a redundant address.

In network environments with a DHCP server, if the camera's IP
address setting is [Manual setting], change it to [Auto assign] (p.17).
