Phenomenon: from NAS separate one CIFS file system sharing, client windows10 the error message "the mapped network drive cannot be created due to the following error: the specified network name is no longer available".

Troubleshooting, generally first check whether the function is installed or not, that is CIFS on the control panel-- program-- start off

When it was not installed, it was solved after installation. This time it was installed on the client.

Let's take a look at the services. Are some services started? For example computer browser wait, there is no problem.

Finally, we can only see that the protocol version does not correspond.

Solution:

1, install the network packet capture tool on the client, such wireshark.

1, when mounting, the packet capture analysis found that there was a problem and the protocol version was incorrect.

2, find a way,

Powershell run the following command:

Get-SmbServerConfiguration

Get-SmbServerConfiguration | Select EnableSMB2Protocol

sc.exe qc lanmanworkstation    //查看用的smb几

Last run: SC .exe config lanmanworkstation depend= bowser/mrxsmb10/mrxsmb20/nsi

SC .exe config mrxsmb20 start= auto

then restart, complete, Mount successfully.

Summary: it is stored SMB the protocol does not match the protocol of the client. SMB the protocol can be automatically matched.
