How do I enable SMBv1?

Control Panel > Programs > Turn Windows features on or off > check SMB 1.0/CIFS File Sharing Support. But note: SMBv1 has security vulnerabilities.

How do I check which SMB version is in use?

Open PowerShell and run: Get-SmbConnection to see active connections and their SMB dialect version.

Windows Network Error 0x80070035 — Network Path Not Found

Warningnetwork

Overview

Windows error 0x80070035 means the network path was not found when trying to access shared folders, printers, or network resources on another computer.

Key Details

Error 0x80070035: 'The network path was not found' when accessing \\computername\share
Common after Windows 10/11 updates disabled SMBv1 for security
Network discovery and file sharing may be disabled on the target machine
Windows Firewall may be blocking File and Printer Sharing
Computer name resolution (DNS/NetBIOS/WINS) may be failing

Common Causes

SMBv1 disabled and target device only supports SMBv1 (older NAS, printers)
Network discovery turned off on one or both computers
Windows Firewall blocking File and Printer Sharing ports (TCP 445, 139)
Computer name cannot be resolved — NetBIOS/DNS failure
Different network profiles (Public vs Private) on the computers

Steps

1Ping the target by IP: ping 192.168.x.x — if this works, it is a name resolution issue
2Try accessing by IP instead of name: \\192.168.1.100\sharename
3Enable network discovery: Settings > Network > Advanced sharing settings > Turn on network discovery
4Ensure both PCs are on Private network profile, not Public
5Check Windows Firewall: allow 'File and Printer Sharing' for Private networks
