Step 1: Test connectivity with RN150

1. In the RN150 Interfaces section, select the TCP connectivity check option.
2. Enter the IP address and SMB port of the target device (typically port 445).
3. If the test result is “Success”, SMB traffic is reaching the server.
4. If the test fails, review network access restrictions (firewall rules, routing, or local server policies) to allow SMB traffic between the RN150 and the remote server.

Step 2: Confirm SMB status on the server

If connectivity is successful, verify that SMB is enabled on the target server.

1. Open PowerShell on the server.
2. Run the following commands:

Get-SmbServerConfiguration | Select EnableSMB1Protocol

Get-SmbServerConfiguration | Select EnableSMB2Protocol

Get-SmbServerConfiguration | Select EnableSMB3Protocol

Each command returns True (enabled) or False (disabled) for SMB1, SMB2, and SMB3.

Step 3: Enable SMB if required

If any SMB version you need is disabled, enable it using PowerShell:

• Enable SMB1

Set-SmbServerConfiguration -EnableSMB1Protocol $true

• Enable SMB2

Set-SmbServerConfiguration -EnableSMB2Protocol $true

• Enable SMB3

Set-SmbServerConfiguration -EnableSMB3Protocol $true

TIP: By default, SMB 3 is the preferred version, but all versions (1, 2, and 3) are supported. The session will utilize the highest protocol version available on the server, ensuring compatibility with clients and applications.

For additional guidance, see Microsoft’s official documentation: Microsoft Documentation: Detect, Enable, and Disable SMB v1, v2, and v3.
