      I asked them how I'm supposed to troubleshoot when they take away my layer 3 troubleshooting tools such as tracert (to show the hops = layer 3, right? )

      That's correct, that's layer 3 (routing.) But what's expected to be the case is layer 4 (ports).

            Wouldn't test-netconnection destination:port work as well for this, assuming @WrCombs is on windows?

                  Good video.

                  The only addition I'd like to make is that you want to do ping first. Not primarily to see if its working or not, but to test DNS / hostname resolution.

                  If you ping abcxyz123.com and you can see that it's gets the IP address, you know that there you don't have a problem with the hostname resolution.

                  Next step after testing with (ping, telnet, wget etc) is to get serious and test tcpdump/wireshark. Basically recording network traffic to analyze what happens.

                  BTW, on windows telnet is not enabled/installed by default.
