Having trouble sharing files between Vista and Mac OSX?

One of the new default Vista security policy settings needs to be adjusted

For Vista Ultimate:

Start,Run secpol.msc [enter]

Click on Local Policies then Security Options

Navigate to
Network Security: LAN Manager authentication level
double-click to display Properties.

The default Windows Vista policy is NTVLM2 responses only.
Use the drop-down arrow to change this to

LM and NTLM – use NTLMV2 session security if negotiated

For Vista Home Premium:

Open a cmd prompt “as administrator” and ack the prompt

Type regedit [enter]
Navigate to

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa

If it doesn’t already exist, create a DWORD value named LmCompatibilityLevel

Set the value to 1 and reboot

  1. You replied to my post on Microsoft’s Windows Vista Community boards, pointing to this article. I have "Vista Business" which it turns out, functions as Vista Ultimate for the purpose of altering the authentication process.
    I’ve managed to connect to my Mac OSX machine now. Thank you.
    I’m still really stumped as to why Microsoft would ship Vista with the ability to connect to a Mac turned off. My mind, it boggles.
