Windows uses a 9x9 instead of 8x8 board for beginner mode.

On Windows XP (and newer), calling NetUserChangePassword with a NULL
domainname parameter creates a user home directory, iff the machine is
not member of a domain.  As we don't want to clutter up the folder
containing the home directories, specify \\127.0.0.1 as domainname to
access the local samdb.

This prevents conflicts with WINED3DRS_ZWRITEENABLE.

For a domain member, the domain info contains meaningful implementation.
It makes no sense to check for the standalone case only.
