This is insiders build.

Only out of the box windows server was installed, nothing was added, drivers are out of the box, basically full clean install of windows.


Do you have an mDNS responder installed ( like Apple's Bonjour?)

No, nothing was installed, only windows.

 

Nothing is in drivers/etc.

 

Two computers are connected with a layer 2 switch.

Only 2 computers exist in this network, nothing was changed or added, clean windows install only.

Same happens with build 17763.55 (public).

 

I will try again today with public .107 release, also original .107 public ISO files and report back.

17763 in any form was never made available to Server Insiders. The last build that was offered to Insiders was Build 17744.  17763.1 was live very briefly on some external channels on 10/2 but almost immediately removed from all external channels. 17763.107 was not made available externally until today, 11/13.  How did you obtain the .107 build in time to provide feedback on 11/6?

    Before MS took down all the links,  Windows Server 2019 evaluation was available for download, this was 17763.1 "trial", same as full version but trial version.

    17763.107 was available for Windows 10 insiders as "windows10.0-kb4464455-x64.cab"

    http://download.windowsupdate.com/c/msdownload/update/software/updt/2018/11/windows10.0-kb4464455-x64_de985f6d38215b316470dbecabb453c762a217af.cab

     

     

    Anyone can use DISM in powershell to install and upgrade 17763.1 (ws2019 trial) to .107, this also applies to windows server as both windows 10 and server share almost the same code.

     

    So Windows server 2019 17763.1 (trial) + kb4464455 = 17763.107 (trial)

     

    If you do this you get Windows Server 2019 17763.107, which is for "insiders" to test things out.

     

    So this was the method i used to test new patches.

    I will again download the new updated trial version when links show up:
    https://www.microsoft.com/en-us/cloud-platform/windows-server-trial

    And test it again, fresh clean install and report back.

      This ".local" bug might also be a related problem for this:

        .local bug still present in 17763.253, Windows 10 Pro 17763.253 does the same.

         

        While pinging or trace routing a windows name in local network, ipv6 always returns .local

         

        Example:

        Pinging SEA.local [fe80::49ab:74ed:a10:32f7%3] with 32 bytes of data:
        Reply from fe80::49ab:74ed:a10:32f7%3: time<1ms

         

        If IPV6 is turned off and only IPV4 is used it always displays normal name "SEA" Example:
        Pinging SEA [192.168.0.4] with 32 bytes of data:
        Reply from 192.168.0.4: bytes=32 time<1ms TTL=128

        .local name only appears if ipv6 is in use, because of this bug some network shares might not work correctly as SMB uses local ipv6 addresses to resolve Windows name.

         

        *This does not happen in Windows Server 2016 (all latest updates). Windows Server 2016 always displays correct name via ipv6 local name in my example:


        Pinging SEA [fe80::49ab:74ed:a10:32f7%3] with 32 bytes of data:
        Reply from fe80::49ab:74ed:a10:32f7%3: time<1ms
