If you try to connect to a non-windows SMB share from Windows 8 you receive an error 1208 after attempting to authenticate.
This behaviour may be due to the "Secure Negotiate" feature added to SMB 3.0 for Windows Server 2012 and for Windows 8, which relies on the correct signing of error responses by all SMB 2 servers (including those supporting only protocol versions 2.0 and 2.1). Some third-party file servers do not respond with a signed error response causing the connection to fail.
From an Administrative powershell console:
Set-SmbClientConfiguration -RequireSecuritySignature $true
Press 'Y' to accept.
