There are a least two timeouts that I've found that can affect domain logons

	-- Roaming profile logon timeout: When a user with a roaming profile attempts to logon to a Samba domain Windows will display the Welcome screen for 30 seconds before enabling the user's desktop. This bug does not affect Active Directory logons. Setting the GPO below to 0 seconds will work around this timeout.

        \\Computer Configuration\Administrative Templates\System\Set maximum wait time for the network if a user has a roaming user profile or remote home directory
        Set to: 0

	-- Synchronous Logon script timeout: When the local Computer GPO is set to "Run logon scripts synchronously" Windows 7 displays the Welcome screen for 30 seconds before enabling the user's desktop. NOTE: this bug may only be extant in Windows 7 Professional, not Enterprise or may have been addressed in service pack. Creating the following REG_DWORD registry key will work around this bug:

        Set to: 00000001

There is also the solid color background bug (again, it may have since been addressed in a service pack): Change the background color to any .jpg image.

Don't know.  The %a switch hasn't worked in our shop for some time.  Windows 7 will tag the profile folder listed with a .V2 extension or will expect a .V2 extension.

Default User profiles do work with Windows 7 and Samba.  See the article for Windows 7 default profile details:

We create a local group policy that we copy from the server via logon script at logon time.  Works great for bot WinXP and Windows 7.
