Hi.
I'm at my wits end.
My network infrastructure is okay, and almost all network services running on my computer are accessible to computers beyond. (Remote Desktop, Apache, etc.) Internet connection is fine too. I am using it to write this post! But no one from outside can access my network shares over SMB. Worse, I cannot access my shares from within my own computer. I tried navigating to the following in File Explorer:
  • \\COMPUTER-NAME: List of shares appear. But I cannot open any of them. Error 0x80070035. (Well, really, my computer isn't called "COMPUTER-NAME", but I am sure you understand why I am not writing its real name.)
  • \\192.168.1.70: Does not connect at all.
  • \\localhost: Does not connect at all.
  • \\127.0.0.1: Does not connect at all.
Things that I have tried so far:
  • Uninstalled COMODO Internet Security
  • Disabled and re-enabled SMB
  • Restarted the computer as well as the "lanmanworkstation" and "lanmanserver" a thousands of times in many different occasions.
  • Released and renewed my DHCP-assigned IP address
  • Tried Windows 10's Network Reset feature
  • Uninstalled every single adapter using Device Manager and let Windows reinstall them. The first time I did this, the problem went away! But then, the problem returned and repeating this step didn't help anymore.
  • Tried "netsh int ipv4 reset c:\reset.log" suggestion from a Microsoft support person. It has no effect and "c:\reset.log" is not created. And anyway, I don't think this is the problem.
  • Set the adapter to force enable NetBT
My computer is running Windows 10, version 1803 build 345.
 
Oh, yeah. Done that too. Also did a Repair-WindowsImage -Online -RestoreHealth. Didn't help. I ended up using Windows Setup to fix the problem.
 
I had a similar problem: I could not access a PC in the local network that I did in the past but others could.

I had to do a repair upgrade to fix the problem.
