What thread are you responding to here? I don't see any others in the thread yet I see other messages from Ale.<br>

I agree that verifying basic connectivity using telnet command is a valid troubleshooting step.<br>
telnet <DNS host> 53<br>
If that doesn't work nothing else is likely to succeed.<br>
<br>
Use of "nslookup" is deprecated for basic resolution - one should use "host" instead.<br>
<br>
Using dig is better than nslookup for DNS troubleshooting.<br>
dig @<DNS host> <options/target domain><br>

I was attempting to test the dns configuration via nslookup and it couldn't connect to the dns server. I was doing elementary troubleshooting which involves checking to see if the port was open and the easiest way to test that is via telnet, as far as I know.<br>
