Symptoms

Windows clients using SMB 3.1.1 lose access to SMB Shares after updating to Windows 10, version 1903.

Cause

This issue is due to two negotiation contexts found in SMB 3.1.1 that FluidFS version 6.0.300135 and lower does not support.

Resolution


Identifying the error

The error can be identified from the following error messages:

  • The client sees the following error message while accessing the SMB share:  
    Windows cannot access "\\servername" check the spelling.... Error code 0x80004005 Unspecified error
     
  • The following error message appears in the Windows event viewer: 
    The server does not support any dialect that the client is trying to negotiate, such as the client has SMB2/SMB3 disabled and the server has SMB1 disabled.
     
  • If using Universal Naming Convention (UNC) path: 
    0x80070043 Network name cannot be found
  • Error message in Network traces: 
    STATUS_INVALID_PARAMETER
     

Note: The SMB clients must disconnect all the SMB server shares in order to negotiate the appropriate dialect according to the parameter value.

 
FluidFS version MR640 addresses this problem. Contact support and reference This article.


The alternate workaround is available by following the steps below to disable SMBv3 and use SMB v2 instead.
This can be accomplished using the Dell Storage Manager or using CLI.

  2. Go to Client Accessibility
  3. Select the Protocols tab
