Network home permissions -- SMB connection on Win2003 Server

Has anyone had any problems with permissions with SMB network home folders on a Windows 2003 server?

With 10.4, our users can connect and edit all of the files in their home folder. They also have no access to any other home folders other than they can see the folder name.

With 10.5, their root home folder is locked and they have read-only access to the same folder with the same permissions as 10.4. Other mac-created folders such as Dekstop, Documents, Music, Library, etc. list them as "custom access" but the users do have permission to create and edit files in these folders. Folders created by windows (My Music, My Pictures) are locked and have read-only access like the root home.

This issue is making it so the users cannot login. They get the "Your are unable to log in to the user account "xxxxxx" at this time - Logging in to the account failed because an error occurred"

These computers are working file for home folders that connect via AFP to a mac server. It's just SMB to Windows.

Any help would be appreciated.

Thank you,
JB
