Windows PC on Network shows up but I can no longer connect to it.

I have a Windows 7 desktop PC that's connected to my network.  When I open File Explorer, I can see it on the network.  Until a few weeks ago, I was always able to connect to it using Remote Desktop.  Then all of a sudden, it stopped working.  I have 2 Windows 11 laptops, both fairly new.

I have another Windows 10 desktop on the network and I can not only connect via Remote Desktop, but I can also clck on it in File Explorer.

I can't figure out what changed or how to fix it.

Thank you in advance for any help you can provide.  This is what I'm seeing in File Explorer.  I can connect with no problems to DELL_NAS.  I can't connect to DESKTOP-PC.

  • hi Jim_S61​ The fact that DESKTOP-PC still appears under Network means network discovery is working, but that doesn't necessarily mean RDP or file sharing is working.

    A few quick tests:

     On the Windows 7 PC, confirm Remote Desktop is still enabled under System → Remote settings.

     From a Windows 11 laptop, try RDP using the PC's IP address instead of its name.

     Test the connection with:

      `Test-NetConnection <IP-address> -Port 3389`

     For file sharing, try `\\<IP-address>` in File Explorer.

    If the IP address works but `DESKTOP-PC` doesn't, the problem is likely name resolution. If the IP connection also fails, check the Windows 7 firewall and Remote Desktop service.

    One other thing to keep in mind: newer Windows 11 releases have tightened SMB security, so an old Windows 7 SMB configuration can sometimes be visible on the network but no longer accessible.

    The IP-address test is probably the quickest way to narrow this down.

      Thanks.  I will try what you suggest and see what happens.  I'll come back and let you know what happened.
