D'oh! .
Eu deveria ter reiniciado meu cliente (s) antes do teste - isso teria ajudado. Acontece que isso não tem sido sobre domínios estrangeiros, apenas um problema temporário de verificação de assinatura do SMB.
Windows 8 1 : as reconexões de SMB falham com a "Assinatura inválida" atualização do servidor para o SMB 3.0 2 :
- The Windows 8 client maps a share on a server with the SMB 2.1 dialect, the server’s highest dialect.
Example using Powershell command: New-SmbMapping -LocalPath Y: -RemotePath \FileServer\Share
The server disconnects TCP and its software is upgraded to a version that supports SMB 3.0.
The client negotiates SMB 3.0 dialect, the newest server’s highest dialect, and attempts re-connecting to the same share.
The server fails to validate the signature the client sent in the IOCTL FSCTL_VALIDATE_NEGOTIATE_INFO. The server returns an error ACCESS_DENIED to the client.
[...]
A possible workaround is to have the Windows 8 client disconnect and delete that connection/session before it can re-establish a new connection. This requires un-mapping the drive (and wait for about 20 seconds for the client to cleanup data related to that connection entry) and then remap it again.
A client reboot the client will also achieve the same result but it is not required.
