Technical Information

By default, Windows Vista and Windows 7 use NTLMV2 for authentication when attempting to map network drives to Samba network shares. This problem can be resolved by making a change in the Windows Vista or Windows 7 registry. The necessary change switches Windows's authentication policy from "NTLMV2 responses only" to "LM and NTLM - use NTLMV2 session security if negotiated."
