I upgrade my Mac to Leopard yesterday and I couldn't logon on to my Windows 2003 server that was running SFM. I could log on to the server running Extremez-ip. I had a feeling it was due to the way Leopard was sending the password, and indeed it was.

I went to Computer Management, right clicked on Shared Folders, and chose, Configure Service for Macintosh.

Set the Enable authentication box to, Apple Encrypted or Microsoft and it will work fine.
