Hi,

I've already enabled SMB multi channel on Windows server 2019 and how to ensure that SMB is fine and working on that server?

After enabling SMB multi-channel on your Windows Server 2019, you can verify that SMB is working properly by performing the following steps:

Check SMB version: Verify that the SMB version you enabled is running by running the command "Get-SmbServerConfiguration" in PowerShell. This command will display the SMB version currently configured on your server.

Check SMB share: Verify that SMB shares are accessible by trying to access them from another computer on the network. You can do this by using the UNC path to the SMB share, for example: \servername\sharename.

Check SMB performance: Test the performance of SMB by transferring files to and from the server. You can use tools like Robocopy, PowerShell or File Explorer to test the transfer speed and latency.

Check SMB status: Check the status of the SMB service by running the command "Get-Service -Name "LanmanServer"" in PowerShell. This command will display the status of the LanmanServer service, which is responsible for the SMB protocol.

Check SMB event logs: Review the Windows event logs for any SMB related errors or warnings. Look for events related to SMB, such as "SMB Server" or "SMB Client", and investigate any issues that are reported.
