    Win10 1803 Loss of Direct Ethernet Link between 2 PC's.


    Hi,
    Subsequent to 1803 upgrade I have lost the direct ethernet link I had established between my two Win 10 Desktop PC's. Have tried everything to restore it but to no avail. If it is not possible to do so (and I suspect that may be the case), is there any way I can add my 2 PC's to the Media Streaming Options Local Network menu (see attachment for clarification). I'm guessing that because my ethernet link was independent of the home group, the two PC's did not get a mention there. I have found a video showing a possible restoration of inter-pc linking but it is dependent upon both computers being shown in the menu. Would really appreciate any assistance. Many thanks - Bob Deb.

    Homegroup is removed from Windows now. If you have two PC's connected by a cable from PC to PC they both need a static IP in the same range and subnet as there is no dhcp server. Open a cmd prompt type

    Ipconfig /all

    Do it on both PC's post results

    The issue with Windows version 1803, is that for some reason it is not discoverable by default. (go figure, must be a bug)

    Here is how to make it all working again:
    1. Open Sevices
    2. Set Function Discovery Provider Host startup type to Automatic (delayed start) on both computers.
    3. Set Function Discovery Resource Publication startup type to Automatic (delayed start) on both computers
    4. For now, manually start both the above services on both computers
    5. Make sure both your computers connections are set to Private Network
    6. Make sure both computers has Network Sharing enabled in Control Panel\All Control Panel Items\Network and Sharing Center\Advanced sharing settings under Private Network section
    7. Make sure both computers has File and Printer Sharing enabled in Control Panel\All Control Panel Items\Network and Sharing Center\Advanced sharing settings under Private Network section
    8. In File Explorer, under Network, you should now see both your computers
    9. On both devices go to Windows Media Player and click on the Stream button down arrow
    10. Select More Streaming options and turn on the service if disabled, in other case you should now see the usual interface


    Doing all the above, I get this:
    Click image for larger version. 

Name:	streaming_service.png 
Views:	2 
Size:	41.0 KB 
ID:	190551
    Clicking on either, ASUS-U46SV: U46SVMedia: OR ASUS-UX305CA-PU: UX305Media: fires up, Windows Media Player and I can see all media available and successfully stream data over from one device to the other.


    Hope this helps, and please let me know if you need any further assistance.

    A question for clarification: does the statement "Subsequent to 1803 upgrade I have lost the direct ethernet link I had established between my two Win 10 Desktop PC's" imply that the "direct ethernet link" is using a Cross-over cable and nothing else between the 2 computers, no Router, no Switch?

    Clarifications & More Thoughts on the Problem


    Thanks for your prompt responses, which provided me with food for thought to look further into the problem but it remains unsolved. In response to Samuria and Berton, the inter PC connection is a direct crossover category 5 ethernet cable between the ethernet ports of each PC. Attachments 'ipconfigs' & 'Network Adapter Status' relate to your responses, the latter indicating that there appears to be an exchange of data between the 2 PC'sover the link.
    In response to slicendice, everything went fine up until item 5 'Make sure both your PC's are set to Private Network. As outlined in the attachment 'Stuck on Public 01' the ethernet link is set firmly in the public domain. I found an on line site detailing the method of changing it to private however it appears not to be relevant to my link configuration. In 'Stuck on Public 02 I have included details of the file explorer - network - associated Users folder, the properties of which seem to confirm that file sharing is just not on under the current config.
    I'm hopeful that the attachments are legible when downloaded and may offer some clue as to which way to go. It appears that making the link network Private is the first priority, after which success may not be far away. I would appreciate any assistance that anyone may be able to offer in achieving that goal. Once again many thanks - Bob Deb

    @Bob Deb

    Try this on both computers:
    1. Open PowerShell or PowerShell ISE with elevated privileges (Administrator)
    2. Type Get-NetConnectionProfile
    3. Take note of the index number of the Ethernet connection
    4. Type Set-NetConnectionProfile -InterfaceIndex XXX -NetworkCategory Private where XXX = the index number of your network interface

    Results Using Powershell ISE


    Hi,
    Using Powershell ISE as you directed I was able to change the ethernet network from Public to Private on both PC's. Still no file sharing with this configuration, the Share "button" (for want of a better description) still remains masked out in the properties of both PC's Users folders. In addition, the ethernet connection defaults back to Public on PC reboot. I'm beginning to think that Microsoft may have won the day on this one. I have been using Google Drive file sharing as an alternative since the ethernet link failed, but it falls a long way short of what used to be. I am often transferring batches of up to 100 jpg images, each one in the order of 1MB or so and the upload/download/unzipping is proving to be a cumbersome and time consuming procedure. I can only hope that Microsoft doesn't render flash drives inoperable in future annual Spring (Autumn for us) Win 10 updates. Many, many thanks to those who offered advice, it has increased my knowledge enormously. As an old ex electromechanical man nudging 75 years of age I welcome any opportunity to delve into the ethereal world of software. On this occasion however, I'm prepared to throw in the towel and declare Microsoft the winner. Many thanks again - Bob Deb.

    That is almost certainly the case except it has been years since pcs needed a crossover cable. Any ethernet cable will do on a modern pc.

    @Bob Deb

    You already have the ethernet link up and running. You should be able to share a folder on for example from PC-3440AN and it should appear in the network view on PC-VM3000 when expanding the PC-3440AN tree.

    Then it's just as easy as making sure the computer has at least read access rights, and you can copy the files over.

    Isn't it odd that you can safely connect a non windows tablet or phone via usb3 and that device can be seen as a drive, but if you try to connect two pcs via usb3, you cannot do that AND worse still, you can fry the usb port(s) and/or mobo(s), or even worse - cause a fire!

    You can buy special cables that allow direct usb3 to usb3 cable connection.
