Vista, Windows 7, 8, 8.1, and Windows2008 r2 use NTLMv2 by default.
Older implementations of Samba however, don't support this and will return a password failure.
Fortunately you can tell Vista and Windows 7 and 8 (and I presume Server 2008 as well) to use the v1 protocol if the v2 is not available.
For Windows 7/8/Vista Pro/Business:
1. Start -> run -> secpol.msc
2. Local Policies -> Security Options -> Network Security: LAN Manager Authentication
3. Change NTVLM2 responses only to LM and NTLM - use NTLMV2 session security if negotiated
If you are stuck with a Home edition of Windows, then there is no secpol.msc.
Instead use:
1. Start -> Run -> regedit
2. navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlLsa
3. for LmCompatibilityLevel, change the 3 to a 1
4. Rebooting might be necessary ...
