Attempt to install DNS Server failed with error code 0x80070643. Fatal error during installation RRS feed

  • Question

  • I have been trying to install DNS role on my server, it has become a frustration and pain point, I keep getting this error. Any way I have already downloaded HotFix Windows6.0-KB975654-x64 for my server, and followed instrcutions to install a patch to remove restrictions for network adapters, I have a 2 port Intel server adapter as well as a 4 port Intel server adapter, Iorigiannly had all 6 teamed, but I took a chance and removed one from the team and assigned it a static so I could attempt installing DNS role after patch with a 5 port team and a standalone port, both have static IPs. but I keep getting the same error.

    If anyone has an idea I am more than happy to provide logs, or anything necessary to get this role installed, and working

  • In my case I had changed the default dynamic port range to only 255 ports. I changed the setting back to 16383 ports and was able to install DNS without any error.

    You can refer to for more information about default ports.

  • Thank you very much Deval!!, I have been pulling out my hair trying to figure out why DNS won't install.... then reading this post I remembered I had to to change the RPC dynamic range down to 255 like yourself, changing it back to defaults work like a charm, wish I can give you more points!

  • This was indeed a solution for me also! Any idea why this fails when using a smaller range?

    I changed the range after the installation and DNS still works fine. So this is only a requirement at installation time?

  • Followed your advise as I had configured only 500 dynamic ports for RPC (as per security's recommdation).  All other TCP/IP settings on the DCs were static and AD DS was fully functional (minus getting the DNS role on the rest of my DCs).

    Tried everything I could think of but the DNS role would simply not install.  Increased the ports to 2000 and DNS loaded without any issues.

  • i had the same problem and did the following command and removed the IP of DNS server

      this command will set the port no for DNS

    • netsh int ipv4 set dynamicport tcp start=10000 num=1000
    • netsh int ipv4 set dynamicport udp start=10000 num=1000
    • netsh int ipv6 set dynamicport tcp start=10000 num=1000
    • netsh int ipv4 set dynamicport udp start=10000 num=1000
