problem accesing a shared folder in a MAC from Vista

Discussion in 'Windows Vista Networking' started by Ignacio Machin \( .NET/ C# MVP \), Jul 19, 2007.

  1. Hi,

    My wife has a MAC notebook and when I tried yesterday to access a shared
    folder I was presented with the login dialog, I put the correct
    username/password but Vista kept saying it was incorrect (apparentely it
    include the name of my PC in from of the username I was using)

    I know the username/password is correct cause when I tried the same from a
    VPC I have running in my Vista machine I had no problem accesing the shared
    folder in MAC.

    Can anybody clarify why Vista is incapable of doing something as simple as
    accessing a shared folder in a remote computer?
    And of course, how to solve it :)

    Thank in advance,

    I assume that you have set up Windows sharing correctly on the Mac. If
    not, you need to do this.

    To enable Windows Vista to connect to Mac OS X with Windows File Sharing
    enabled, you will need to change the following policy in Windows Vista:

    Start>Run>secpol.msc [enter]

    Click on "Local Policies" --> "Security Options"

    Navigate to the policy "Network Security: LAN Manager authentication
    level" and double-click it to get its Properties. By default Windows
    Vista sets the policy to "NTVLM2 responses only". Use the drop-down
    arrow to change this to "LM and NTLM – use NTLMV2 session security if

    In Vista Home Premium, you won't have this tool so per Steve Winograd, do:

    1. Run the registry editor and open this key:


    1. If it doesn't already exist, create a DWORD value named

    3. Set the value to 1

    4. Reboot

    Don't forget to create identical user accounts/passwords on both machines.
