    Default ping computer1

    Hi all,
    While studying using MS-PRESS 2nd edition, I came across the following command in a troubleshooting lab, in step 10 on page 5-14:

    ping computer1

    According to the book, it should say: Pinging computer1.domain1.local.

    Unfortunately, this isn't happening.

    I'm getting: Pinging computer1

    and I don't want to go too far ahead if I'm missing something.

    P.S. I've completed all of the previous practices/labs.

    Thanks.

    Need to know a bit more. I haven't read through all of the 70-291 press book, so I'm not sure how your network is set up.

    Are you running VMs, or do you have a physical lab set up? Is computer1 on the domain1.local domain? Does pinging computer1 resolve to an IP address?

    Edit: I know these are really basic questions, and you're probably all :rolleyes: with me, but I'm just knocking the easy stuff out

    I appreciate the response and would not roll my eyes anyway.

    I'm running 2 computers that are connected via ethernet cable.

    Yes, Computer 1 is on the domain1.local domain.
    Yes, pinging Computer1 resolves to an an IP address.

    If you are receiving a response of Computer1 instead of Computer1.domain1.local, that means you have something incorrectly setup with DNS.

    Do an ipconfig /all and post the results.

    Yes, the above statement is correct. If you are getting ping computer1 and not the fully qualified domain name, you are pinging the computer most likely via Netbios broadcast and not DNS.

    See if this works:

    -Disable Ethernet Adapter "MyISP".

    -Then set your Ethernet Adapter "Local Area Connection" DNS server to be your domain controller.

    This is just to isolate the issue, mind you. I'm sure eventually you're gonna want that outside line to your ISP up and working again, but for right now lets see what this accomplishes.

    It seems like you don't have DNS set. You'll want to configure that so that it will be able to resolve the computer name by DNS instead of netbios broadcasts. It also looks like your DC isn't pointing to itself for DNS which is something else you would want to fix.

    Agreed. You haven't configured DNS on either network adapter. Make sure that both your DC and your member server point to your DC for DNS.

    Have any of you actually got the MS press book please?

    While I appreciate your support, my point is that I've done everything the book has asked me to do so far but something isn't right.

    The member server is set to obtain DNS server address automatically.

    Actually, I do have MS Press books, but not for the exam you are working on. While you have followed the directions in the lab exactly as they have them laid out, doesn't mean they are right. The books are full of errors, and you might have encountered one. Do a google search for your books errata and see what you can come up with.

    When you did a dump of the ipconfig /all, it didn't included DNS entries for the network adapter in question. Since you configured static ip address, you must also include static DNS server entries. These should point to your DC/DNS server. On your DC, it should also point to itself for DNS, by either using 127.0.0.1 or the statically assigned ip address.

    MS Press book or no MS Press book in the end it still comes down to how to fix the problem. I took a look over that particular chapter and noted a number of references back to chapter 4. I suggest you go and re-read chapter 4 and go through the labs in there again so that you will have a firmer grasp on DNS and NetBIOS and how it all works.
