  • Can’t login to mac from Vista

    Posted on September 9th, 2009 Alan No comments

    For sometime I’ve had problems connecting from my Vista laptop to my MacBook Pro.  I’ve only been  able  to connect  the other way.  Finally a solution.

    This thread recommends the following:

    On the start menu in the search field type “gpedit.msc”, hit enter. This will open the group policy editor.

    Go to “Computer Configruation” –> “Windows Settings” –> “Security Settings” –> “Local Policies” –> “Security Options”

    In the pane on the right side of the screen, select “Network Security: LAN Manager Authentication level.” By default this read “Send NTLMv2 response only.”
    Change “Send NTLMv2 respone only” to “Send LM & NTLM — use NTLMv2 session security if negotiated”

    restart the client

    If you use a famillial vista try this.  You must modify the BDR

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
    DWORD named : LmCompatibilityLevel must set to 1
