Windows 10 unable to connect to shared folder

Question

Hi,

We experienced an issue two days ago, our client windows 10 is trying to connect to a shared folder on windows server 2019

but we received the below error
error code 0x80070035 the network path not found

the client is able to ping the server and the firewall is off

I checked the SMB connectivity event viewer on the client-side

Failed to establish a network connection.

Error: {Device Timeout}
The specified I/O operation on %hs was not completed before the time-out period expired.

Server name: 192.168.5.2
Server address: 192.168.5.2:445
Instance name: \Device\LanmanRedirector
Connection type: Wsk

Guidance:
This indicates a problem with the underlying network or transport, such as with TCP/IP, and not with SMB. A firewall that blocks TCP port 445, or TCP port 5445 when using an iWARP RDMA adapter, can also cause this issue.

Thanks,

Can you please run test-netconnection to the hostname (FQDN and NetBios) of the Windows 2019 Server. Its almost always something really silly.

Test-NetConnection -ComputerName "YourSeverName_orIP_Here" -Port 445 -InformationLevel "Detailed"
