Your cache should now be cleared. This will provide the header information of DNS server requests see screenshot below. For network diagnostics, you can run a ping command in CMD. A ping measures the latency of a connection for a target location. Another helpful command for network diagnostics is the traceroute command.

This is especially handy for troubleshooting connectivity issues. What the command is doing is verifying the route packets take to arrive at their destination. The different stops listed are also called hops. Along with the number of hops, you can see the query resolution time. This information can help you improve your DNS speed or identify problematic routers. Tip : Command Prompt keeps a history of recent commands. If you need to see a command entered earlier in a session, just hit the up arrow key to scroll through them.

This applies when the set and the lookup request contain at least one period, but do not end with a trailing period. The server didn't respond to a request after a certain amount of time and a certain number of retries. You can set the time-out period with the nslookup set timeout command. You can set the number of retries with the nslookup set retry command.

The DNS name server doesn't have resource records of the current query type for the computer, although the computer name is valid. The query type is specified with the nslookup set querytype command.

The connection to the DNS name server or finger server could not be made. This error commonly occurs with the ls and finger requests. The DNS name server found an internal inconsistency in its database and could not return a valid answer.
