Show stop conditions
- The share contains sensitive work data and permissions are unclear
- The network is public or untrusted
Likely causes
- The computer name or share path is incorrect
- The host is offline or on another network
- Network discovery, file sharing, or firewall rules block access
- Name resolution fails even though the host IP is reachable
Quick checks, in order
Confirm the exact share path
Use the format \ComputerName\ShareName and verify spelling.
Test whether the host is online
Check that both devices are on the intended network.
Try the host IP for diagnosis
If IP works but name does not, focus on name resolution.
Review sharing and firewall settings on the host
Change only the correct private network profile or approved organization policy.
Can the host be reached another way?
DNS, NetBIOS, or local name resolution is the likely area.
Connectivity, firewall, VLAN, or host power is more likely.
The share name or permissions are the next checks.
Stop and get qualified help when
- The share contains sensitive work data and permissions are unclear
- The network is public or untrusted
Official support and model manuals
Use the full model number from the rating label. The manufacturer manual is the deciding reference when codes differ by region or product family.
Frequently asked questions
What does 0x80070035 mean?
Windows could not find or reach the requested network path.
Does turning off the firewall prove the cause?
It can create risk and is not a good first test. Verify the correct sharing rules and network profile instead.
