enforcement of smb signing is independent of whether the client is
joined to the DC or not. On Windows, it is controlled by a registry key
that applies to all SMB traffic. It is explained in detail here:

signing" in smb.conf. The default behaviour follows that of Microsoft's
recommendations, i.e. "mandatory" on a domain controller. You could try

increase your speed. Be sure you understand the security implications of
