I recently purchased a HP desktop with Vista Home Premium and tried the Vista Home Premium method that zodieman provided below. After closely following the provided instructions I ran into a problem… Within the REGEDIT program, then trying to navigating, I was only able to go as far as (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa) within the Lsa directory I could not find the LMCompatibilityLevel option to edit. How & Where do I find this line to edit the value? I also searched a recently purchase SONY VIAO only to find the same occurance of no LMCompatibilityLevel. Can anyone help me please!

[QUOTE][u]Quote by: zodieman[/u][p]Yes, Vista defaults to NTLMV2 auth which gives stock Macs and Xserves running SMB headaches. You can downgrade the Vista auth requirements by altering the security policy. Depending on the version of Vista you’re running you can do the following:

If you use using Windows Vista Home Premium you will need to make a small edit to the registry to downgrade to plain NTLM authentication.
Click the Windows menu and type “regedit” in the search field. Press return to launch Regedit. Navigate to :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\LMCompatibilityLevel
And change value of the of default entry from 3 to 1. Click OK to save and you should be able to connect to your Mac clients and Servers.

If you are running Windows Vista Business or Ultimate you may use the “secpol.msc” applet (click the Windows menu and type it in the search field).
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 view network drives based on Samba servers and should fix any issues around using Samba as a Primary Domain Controller.
