    Just wanted to let you know that you are the reason i passed my a+ and network+ exams. Your videos are some of the best study guides on the entire internet, and your cheat sheets that are available on you site are very helpful. Thanks a lot. Please continue making videos and helping all of us looking to continue in our passion of computers.

    Great Videos, sir! Just to add a note for Mac users(and probably Linux users, too): ifconfig in Terminal on the Mac doesn't show you the default gateway/router. Just "ping gateway" will show you the dns name and IP of the gateway and ping it until Ctrl-C.

    Thank you Professor Messer for the exclusive training videos. I am studying for Cisco CCNA and I find your videos very helpful in general. Any videos on Labs and SIMS troubleshoot? That is where I am having the most trouble.

    Curious. When running netstat -b (as administrator on my on personal laptop at home on a network that is in my name) i`m getting 'The requested operation requires elevation' code. Any idea why that might be? Thanks in advance!

    • @professormesser
      @professormesser  7 ปีที่แล้ว +4

      Even if you're part of the Administrator group, Windows will still not run as an elevated user unless you specifically ask for the special permissions. You can right-click on a CMD icon and request to run as Administrator, or Windows 10 may provide an option for Command Prompt (Admin). I usually press the Start button, type cmd, right-click, and Run as Administrator.

    Any ideas??

      You probably need to install the Microsoft Remote Server Administration Tools for your operating system. You can get the tools from the Microsoft web site.

    netstat -b for me comes up as "requested operation requires elevation". I am the only user on the computer however. Anything I can do to solve this?

    • @professormesser
      @professormesser  6 ปีที่แล้ว +5

      When starting CMD, right-click on the selection and choose "Run as Administrator."

      Just means that you need higher privileges on your current log on.

    Why is the -a used with nbtstat capitalized?

    • @MCKejml
      @MCKejml 6 ปีที่แล้ว

      It seems -A is used with an IP and -a with a hostname.

    what are the binaries that you mention in netstat -b, i don't see any binary numbers

    • @professormesser
      @professormesser  7 ปีที่แล้ว +3

      The "binary" is the name of the executable that created the network communication.

    Why would it show stars instead of times?

    • @professormesser
      @professormesser  8 ปีที่แล้ว +10

      You're seeing stars because the TTL exceeded messages are being filtered before they get to your computer. You're probably on a third-party network that is filtering those messages at the firewall.
