File Transfer fails with Samba Mount Failed
Description

Samba Mount Failed with the error "An error occurred conecting to the share: Samba Mount Failed for user username=UserA domain=DomainA". This occurs when SMB v1 has been disabled on the target systems.
Cause

DPAv3 only supports SMB1
Resolution

WORKAROUND 1

Set affinity to LocalServer which supports SMB 2

WORKAROUND 2

Enable SMB1 on the targets systems

This can be checked using Powershell
Get-SmbServerConfiguration | Select EnableSMB1Protocol, EnableSMB2Protocol

To enable SMBv1 on the SMB server, run the following cmdlet:
Set-SmbServerConfiguration -EnableSMB1Protocol $true
RESOLUTION

Upgrade to 2.5.919 and use a DPA v4, which adds support for SMBv2 / SMBv3 for PSM File Transfer

If you are currently licensed for a virtual DPA you can download the virtual DPAv4 from here
If you currently have hardware DPA 3.x appliances and you want to swap these for hardware DPA 4.x appliances, you will need to contact your Sales or Account Rep to discuss this.
When downloading files, the exact/full filename along with the file extension must be specified. e.g document1.docx.
