Hi

I have just replace my old XP PC for a shinny new Vista box, when I try to
connect to a shared folder on the Vista machine from my Mac in the same way
i used to use for XP, I get an invalid username/password error.

Is there something I must change on the Vista machine to make it
authenticate like my old XP Pc did?

Thanks

Steven

I'm assuming that your Mac is using OS X and that you have Windows File
Sharing set up correctly. Make sure you add your Vista username and
password to the users on the Mac. Then see the following:

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
negotiated".

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

1. Run the registry editor and open this key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa

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

3. Set the value to 1

4. Reboot

Thanks for the reply, I did find the solution in a video tutorial
here:-http://www.vistax64.com/tutorials/83931-workgroup-password.html not

Thank you again for taking the time to respond.
