Problem: The Internet Agent has requested a lookup from the Domain Name Server and did not get a response.
Action: Check the resolv.cfg file for correct configuration.
The resolv.cfg file should be in the following format:
domain your_domain_name
nameserver ip_address
nameserver ip_address
nameserver ip_address
The domain name is first, followed by up to three nameserver IP addresses. The following is a sample resolv.cfg file:
domain sgunix.org
nameserver 172.16.5.18
Possible Cause: The IP address to your DNS has changed.
Action: Update the resolv.cfg file.
Possible Cause: TCP/IP is configured incorrectly.
Possible Cause: There is a problem with your network interface card.
Possible Cause: There is a problem with your network cabling.
Possible Cause: The DNS server is down.
Possible Cause: IP filtering has been added to the routers so the Internet Agent cannot see the DNS server.
Action: Ping the nameserver IP address to see if it is reachable from the gateway station.
Action: Ping the LAN segment router IP address.
Action: Make sure the named Internet Agent program is running on the nameserver server.
Possible Cause: Outbound ports are disabled. TCP/IP can use port 1024 through 2099 or some other range of outbound ports for sending.
Action: Check with your Internet service provider for the outbound ports it uses.
