Note: This article applies to the K2000 appliance version 3.2 and older. Version 3.3 and newer of the K2000 appliance uses a newer version of Samba, which supports NTLMv2 authentication.
The issue of Windows Vista or Windows 7 connecting to the K2000 appliance shares that require password can be resolved by following the directions below. Apparently Samba 3.0 has repaired this but in the mean time this should work.
1. Open the Run command and type "secpol.msc".
2. Press "continue" when prompted by Vista.
3. Click on "Local Policies" --> "Security Options"
4. Navigate to the policy "Network Security: LAN Manager authentication level" and open it.
5. By default Windows Vista sets the policy to "NTVLM2 responses only". Change this to "LM and NTLM – use NTLMV2 session security if negotiated".
Once you’ve done this Windows Vista will be able to access the network shares by mapping a drive using the alternate user link.
