DirectAccess 2012R2 NLB and DNS RRS feed

  • Question

  • After i configured DA in NLB, i am getting DNS error status that DNS server is not responding to DNS quires.  NLB VIP became 1st server NIC. I have 2 NIC NLB configuration and going port forwarding to NLB VIP from firewall.

    How to mitigate this problem?

  • Found what was the problem on my configuration.

    Since NLB VIP did not respond when traffic was going from other networks (Internet  included) i had to reconfigure NLB from unicast to multicast. Then thing started to work but i had DNS resolution error.

    Solution:
    A BUG! When you change NLB cluster type, ipv6 that is configured on it gets removed so you have to enter it again. That's the same IPV6 IP under Infrastructure servers - DNS that ends with :3333::1 for your .domain.local

  • Many thanks for this!

    I'd been racking my brain trying to fix this issue, and broke it every time I enabled NLB.

    This solved the problem instantly!
