70-291 DNS Question - Alternate Configuration RRS feed

  • Question

  • In my lab, I was testing the ipconfig /registerdns command on a computer with an Alternet IP (

    I noticed it would not register its IP on my DNS server ( until I made it an actual static IP.

    Is it fair to say that workstations with Alternate Configurations set because of no DHCP server are not able to register its self on a DNS server?

  • A couple of thoughts:

    1. Was the computer's alternate configuration pointing to the DNS server as the preferred DNS server?
    2. Was the computer able to communicate with the DNS server?
    3. Did you attempt to manually register from the client computer (ipconfig /registerdns)?
    4. Did you check the DNS logs (and event log) for entries relating to dynamic registration?

    I haven't heard of a limitation of dynamic registration when using alternate configurations (although that doesn't meant there isn't one).
